  1. ETA2824 Service - The Radioactive Watch! Yes this watch is Radioactive ... so to speak :P It contains H3 Tritium Tubes to illuminate the dial at night. This watch belongs to my brother, and he has owned it for many years. I have to say that Marathon Watches are great "bang for buck", as this watch has served him well over those years, and he rarely takes it off his wrist. Unfortunately, on one of the rare occasions that he did (to wash his hands after work) he dropped it on the ground, and it stopped dead ... right at his quitting time 3:30pm. He was very angry with himself, and asked if I could found out what damage had been done by the drop, and repair it ... of course I was happy to help my bro :) While he was with me, I pulled the Caseback off and could instantly see the problem. The Hairspring was jammed up and the Balance was seized. I told him there also could be broken pivots, and I'd have to dig further to assess the total damage; but not to panic, as all parts for this movement are readily available (at the moment) ... so he left the watch with me. So I removed the movement from the case, pulled the Hands, and the Dial off to inspect the Calendar Works ... everything looked good. Next I removed the Oscillating Weight, and checked that the bearing hadn't been damaged by the impact ... it was fine too. Next I pulled the Automatic Work off the movement, so I could gain access to the main body of the watch. Here's a reference photo of the Automatic Work for ya Next I undid the screw of the Balance Cock and began to gently lift it ... and hey presto, and Hairspring dropped back into place, and the movement started tickin away ... these are a solid movement indeed! I carefully watched the movement ticking away, noting to see that the Pallet was working properly, and that the Train Gears ran smoothly ... all seemed fine, and the problem with this movement was resolved. I could have just stopped there, but this movement hadn't seen a service in over 8 years, and was already out of the case and 1/4 stripped, so I deiced to burn the midnight oil and do a complete service on the watch. And yes, that is a real radiation dosimeter, as I wanted to be sure nothing from those glass vials had leaked into the movement I was handling ... I'm glad to say it was clean B) Continuing with the strip down. All mainspring tension was removed from the unit. Notice with this movement too, that the click is on the Crown Wheel; instead of the Ratchet Wheel. Balance and Pallet was removed Crown Wheel, Ratchet Wheel and Barrel Bridge was removed. This is a reference photo of the Click Spring sitting on the Barrel Bridge. Under the Barrel Bridge there is a small Balance Hack to be removed as well. Next I flipped the movement and removed the Calendar Work. Then the Keyless Work Back the to other side and Train Gear was removed. Here is a reference of the Gear Train. Lastly the Automatic Work was stripped. Back from a bath, and all parts clean and ready for inspection and assembly. All pivots where intact and unburred, no damaged teeth or pallet stones, and no wrapped gears ... GOOD NEWS!! Ready to be put back together! :woohoo-jumping-smiley-emoticon: Nice clean and shiny Gear Train, Train Bridge and Barrel back in place and oiled Back on with the Barrel Bridge, Ratchet Wheel, Crown Wheel and Click Keyless Work clean, oiled and working smooooooth Automatic Work back together as well The rest of the re-assembly wasn't photographed ... sorry guys, it was VERY late, or should I say EARLY, in the wee hours of the morning, and I just got carried away with the build :huh: But it all went smoothly and as per the reference photos early. After the Dial was attached, the hands where next. Let me tell ya, these are NOT easy to fit correctly! With those glass tubes of H3, there is NO room for error fitting them. You literally have a couple of thousands of an inch to play with ... here's the photos to scare ya :o. This type of watch will really test your hand setting abilities. Here's she is all back in the case with the Automatic Work and Oscillating Weight fitted, purring like a kitten! Job Complete!! And as you can see, it now is showing my quittin time of 4:11am OUCH!! :hot: Hope you enjoyed this post as much as I enjoyed working on this movement. It was really nice to finally work on a watch that hasn't been molested, with nice clean screwheads, and no rust to deal with.
  2. Seiko 5J22A Complete Service Hunting through my cupboards I found my old Seiko Kentic "Auto Relay" that I purchased sometime in the 90s, when this was the latest cutting edge Quartz Watch on the market offered by Seiko. It's been sitting for over a decade without use, and I decided to really push myself and, with the Lord's assistance, completely strip and service this watch. So I tracked down the Tech Specs, and if you are thinking of embarking on servicing the 5J22 YOU WILL NEED THEM!! :) So here they are: 5J22A.pdf I will be using the part names from this document for this walkthrough, so download and print it out for you own sanity. The parts in this movement are incredibly small, so much so that my camera had trouble focusing on them ... so part names will help you as much as the visuals aids for this service. Once again, I've had no one to guide me on this, so this is the way "I" stripped the movement down, the correct factory procedure may, and probably does, differ from my way ... so I give a warning here: CONTINUE AT YOUR OWN RISK. Disassembly Unscrew the back cover and store the rubber gasket away safely. With a 2.0mm Screwdriver, pry the Location Ring out with the slots provided in the plastic ring. Remove the Oscillating Weight with a 1.20mm Screwdriver ... and this will be the driver you use on all further screws. To remove the Stem, you need to have the Stem push all the way home, to move the Yoke into the correct position so you can depress the lever (Location shown in picture after I removed the movement to make it easier to see the spot where you push) The movement should now come out of the case along with the internal Bezel Ring. Remove the Hands Remove the 7 screws for the Circuit Block Cover A, and the Rechargeable Battery Clamp (Sorry referred to an older pic to so you the location of screws) Remove the Insulator for Rechargeable Battery, and then the Battery itself. Remove Circuit Block Cover A Remove Circuit Block Cover D Reference picture of Circuit Block Cover D Remove Circuit Block Cover B Reference picture of Circuit Block Cover B Remove Oscillating Weight Bridge Reference picture of Oscillating Weight Bridge Remove Circuit Block Cover C Reference picture of Circuit Block Cover C Remove Circuit Block NOTE: The pin with the yellow arrow pointing to it holds onto the Circuit Block very firmly. Be CAREFULLY and GENTLE, as the Circuit Block can be easily damaged. This is the angle of attack that I recommend. Coming in on an angle just in front of the Crystal Unit, and gently push upwards ... and I mean GENTLY. Patience wins the day! Remove the Intermediate Wheel for the Generating Rotor Remove the Generating Coil Block (grasp with tweezers where indicated with yellow arrow) Remove the Second Coil Block (grasp with tweezers where indicated with yellow arrow) Remove the Hour and Minute Coil Block (grasp with tweezers where indicated with yellow arrow) Remove the Train Wheel Bridge Remove the Second Wheel and Pinion, the Third and Fourth Wheel Remove the Intermediate Second Wheel TIP: Next is this first of three sets of Stators and Rotors that make up this Quartz Movement. Be sure to place all the Stators and Rotors into a piece of Rodico for safe keeping. As shown below: THESE PARTS ARE MAGNETIC AND WILL ATTRACT PARTICLES, SO DO NOT PUT INTO THE BASKET FOR CLEANING Remove the Second Stator and Second Rotor Remove the Minute Wheel and Pinion, Intermediate Minute Wheel, and Setting Wheel Remove the Center Wheel and Pinion Remove the Generating Stator and Generating Rotor Remove the Setting Lever Spring Remove the Yoke and Setting Lever Note: Release tension on the Yoke Spring FIRST Remove the Clutch Wheel and the First Intermediate Wheel for Calendar Corrector Remove the Hour and Minute Stator and Hour and Minute Rotor This side of the Main Plate is now finished ... time to flip it over and start on the Calendar Works Remove the two screws indicated and remove the Hour Wheel Guard Spring, and the Date Dial Guard Remove the Intermediate Date Driving Wheel Remove the Intermediate Hour Wheel, and Hour Wheel Remove the Date Dial Remove the Day-Date Corrector Wheel, Second Intermediate Wheel for Calendar Corrector, Date Driving Wheel and Spring Note the position of tension of the Date Driving Wheel Spring (bottom of page 9 in the Tech Specs) Remove the Circuit Block Spacer ... and the disassembly is complete! I started work on this rather late at night and took my time and studied each part before removing, making sure to document everything carefully. So I'll clean the parts and begin reassembly fresh tomorrow. I can see this one is really going to push my abilities, and I'm looking forward to tackling it and uploading the reassembly steps.
  3. Hello dear watchmakers! I am now working on a SU movement, Slava 2427. It is a manual-wind movement with day-date complication I am trying to assemble the watch back together after service but I am stuck on the day disc. The day disc is fitted OK in my view, teeth underneath the disc interacts with the click and the disc advances naturally as other motion works move clockwise. However, the problem is that the days written on the disc are not in the right position and do not fit inside the day window of the dial. What could I have done wrong?? Thank you!
  4. Good evening everyone. I am new to this forum and i can see we have some outstanding experts on the site. brand new to watch repair and looking to get some advice. I purchased an Omega seamaster quarts 1342 watch (not currently working and not tested) as it was a bargain and understand that 329 is the equivalent of the original mercury battery used when the watch was manufactured? I am hoping the battery change will mean it is functional but in the event it does not work, how easy/costly is it to repair. (I’ve heard parts can turn this bargain into a money pit) would anyone in this community willing to have a go at fixing it after i try battery change? paid service of course. any help advice would be much appreciated thank you
  5. Hello fellow watch freaks. It's been a while since I've posted a service walkthrough, but I had an accident that destroyed my left shoulder and needed surgery. It's been a rough 6 months for me, with a LOT of soul searching throughout my recovery period. But I'm back on the bench ... at least at home anyway; work is a different matter, and my close friends on this forum know about that ... nuff said. This watch is owned by one of my older brother's friends. My older brother is one of the most selfless people I know, and has always been there for me. So when he asked me to do this for him it became TOP priority. It was the first item his friend purchased after he left school and began work: so there's a lot of good memories tied to this watch. As you can see it's an older quartz Seamaster with an 1337 Movement. On first inspection you can see water damage to the Dial @ 3 o'clock. So I wasn't expecting to see a happy movement inside. But when I got the Caseback off things didn't look too bad at all. Just a bit of corrosion from a cheap nasty Chinese battery. The movement still looked nice and shiny and the Stem only had a touch of rust up near the Crown. So this watch looks like one we can save :) Disassembly OK, lets begin. Fist remove the Hands and Dial from the movement. Again, absolutely no moisture damage under the Dial ... this made me VERY happy indeed. So on to the Movement Holder it goes. Remove the Battery Clamp and Insulator Ring. Then remove the 4 screws that hold the Circuit Cover. Note that there is an insulator under the cover. It is very delicate, so great care should be taken when handling it. Once the cover is removed the circuit is exposed; but before removing it, unscrew the 2 screws holding the Coil Protector and remove it. Then unscrew the Coil, and remove the Circuit and Coil. Place both the Circuit and Coil in a safe place to avoid damage, as this parts are obsolete, and if damaged you'll have to scour the internet for a donor movement ... good luck with that!! Next remove the Train Bridge Here is a reference photo of the train. As you can see, the Rotor is a very different looking animal to the modern ETA rotors. Carefully remove all the wheels, and store the Rotor in a safe place AWAY from the rest of the parts to be cleaned ... as this has to be hand cleaned due to it being magnetic. Please Note: There is a very small washer that fits between the minute wheel and the extended pivot of the Second Wheel. Be sure to identify it, and make sure it's put in the small parts container for cleaning. Here's the complete train removed from the movement for reference. Flip the movement over in the holder and remove the 3 screws of the cover that holds the Calendar Ring. As you can see that Motion Work and Calendar Work are fairly complex on this movement. Make sure you take good reference photos and study them carefully so they are not confused with wheels of the train. Remove the Calendar Ring. Remove the Motion Work and Calendar Work. Here's the complete Motion Work and Calendar Work removed from the movement for reference. The Crown and Clutch should now be able to be removed. Flip the movement over once again to tackle the Keyless Work Unscrew and remove the Setting Lever Spring. Lastly unscrew and remove the Setting Lever, Intermediate Wheel and Yoke. The Omega 1337 Movement is now completely disassembled and ready for cleaning. I will post the assembly soon.
  6. Hello.I have been working on a vintage movement. It is German movement, PUW 1561. It is automatic and has date with quickset function by pulling and pushing back the crown. Before I disassembled it, the quickset did not work instead the date changed as hands passed 00:00. However, as I am trying to put the watch back, the date won't change either by quickset or just manually. The date disk won't move no matter how long I move the hands. I think I have assembled the date function part wrong but I have no idea how the parts should fit it. I read a post about servicing this same movement but it did not work for me. (http://watchguy.co.uk/service-arowe-puw-1561/) Could anyone help me how to put the date parts back in?? I attached a photo of the movement I am working on.
  7. I'm having a watch serviced for the first time, its a vintage (1974) Seiko 5 Actus, because its running two mins fast, i don't know its past history. Will a service include regulations or is that a separate service?
  8. I have one of these in for service, cant figure out why the hour hand does not go round when time is set. The hour hand sets OK although sometimes it clicks every hour and other times it runs smooth. The minutes and seconds function fine even when setting the time. http://www.old-omegas.com/1337en.html Maybe a problem with the magnetic wheel on the date set? I looked under the microscope and it looks like the 2 part magnetic wheel on the date side is only rotating on the bottom half and not transferring the force to the top half to the hour wheel. Any ideas on how to remedy it and get her going again?? Omega 1332.pdf
  9. ST96 Restoration Walkthrough I got a new project to start on: restoration of my brother's watch he got for his 9th birthday. This is not an expensive watch in dollar terms; but the memories and history are priceless, and one I really want to restore to excellent condition. It stopped running decades ago, but he has still kept this watch for nearly 40 years, how many of us can say the same about their first watch?! My brother has placed a lot of trusted in me to restore this watch, and I want to repay that trust by restoring this watch to the best of my ability. Note his name (blocked out) and date it was given to him are engraved on the back plate. After opening the back I was pleasantly surprised to see it was a 17 Jewel movement ... so for it's day it was a proper watch; and not a cheap throw-away item you buy at a service station. This would have been purchased at a professional jewelers back in 1975. Unfortunately, the first issue was discovered. The locating ring is missing, and the only thing holding the movement in place is the stem ... not good. So the disassembly begins. Once removed from the case, the hands and dial were removed to get to the movement. Then the first of the motion work is to be removed. Remove the Hour Wheel Then the Minute Wheel pinion and it's Guard Plate. Next remove the intermediate pinion for the Minute Wheel. Also notice the over oiling of this movement, someone got very enthusiastic with their oiler! Again oil everywhere! Here's is the Minute Wheel glued to the Guard Plate with oil. Pull the Cannon Pinion and remove the Endstone. Release the spring tension from the Mainspring. Remove the Ratchet Wheel and Crown Wheel Look at the flood of oil over the bridge! Second issue with this movement. The thread for the Crown Wheel Screw is stripped. It looks like someone has been inside this watch, many years ago, to try and see why it stopped running, and unscrewed this anti-clockwise; not knowing that it's a reverse threaded screw, and stripped the thread :( Continuing with the dismantling ... remove the Click and Click Spring. Note the orientation of the spring. Remove the Barrel Bridge Remove the Balance, Pallet Fork Cock, and the Fork. Remove the Centre Wheel and Third Wheel. Remove the Escape Wheel and the Mainspring Barrel. Remove the Endstone from the Centre Wheel Bridge, and then remove the bridge itself. Remove the Centre Wheel Whatever lubricates were used on this movement it has crystalized into a nasty mess. I tried to capture it on this photo, but it didn't really comes out as I'd hoped .... but notice all the white specs. To finish off, remove the Keyless Work. Start with removing the Setting Lever Spring. Next unscrew the Setting Lever, remove tension from the Yoke Spring, and then remove the Yoke. Note: more evidence of over oiling it present here. Note the orientation of the Yoke Spring. Lastly, remove the Endstone from the Main Plate, and you are complete. After fully dismantling the movement, I opened up the Mainspring Barrel and found what the original issue must have been ... a broken Mainspring. This is the third issue that needs to be addressed to restore this movement. Probably broken by a young boy over winding his watch :) Note: The break in the spring, and how it doesn't attach to the Barrel Arbor any more. So with a missing Locating Ring, stripped Crown Wheel thread in the Barrel Bridge, and a broken Mainspring: I need some spares!! .... off to the Fleabay .... Being a movement in an obscure brand of boys watch, I wasn't exactly hopefully in finding spares readily available ... but praise the Lord Jesus Christ, they were there in abundance! It seems India has cornered the market on ST96 Movements :P They had it least 10 to choose from. I ended up choosing a "Rare" Tressa model in "Excellent" condition, that was a "MUST SEE" I placed an offer for AU$28 on this rare collectable (including shipping) and won it **chuckle** Regardless of the hype, it is guaranteed to work for 12months, and is the movement I require to secure the parts I need. Including that all important Locating Ring. With free shipping comes a long wait for delivery to Australia ... 12-22 days. So while I'm waiting for the watch parts to arrive, I'll clean up the case and bracelet. ... to be continued
  10. ETA 955 Service Walkthrough "The Workhorse of Highend Quartz" The ETA 955 and 956 Quartz Movements are the most commonly found movement in high-end quartz watches with three hands and a date feature. You will find them in Omega, Tag, and many other brands on the market. For this walkthrough I will be using an 955.412 Movement as my example; but the 956 is so similar to the 955, that this walkthrough will suffice for both. Please note that the numbers after the decimal place only relates to the factory in which the movement was made, so yours could read 955.112, or another factory number ... regardless, the parts are identical and interchangeable. As with all movements, quartz or mechanical, they have a service interval that should be adhered to for longevity of the movement. With quartz movements when the lubrication becomes dried out, or the movement becomes dirty, they will draw more and more current from the battery in order to maintain accurate time keeping. The ETA 955/6, when in optimum condition should draw around 800nA ~ 1.5uA, if the movement is drawing more power than this, a service is required. If a service is not performed, the battery life with decrease markedly, and can go as far as drawing more power from the battery than it was designed for, and damage the battery and cause it to leak and corrode your valuable time piece. Service Manual for the 955/6 Movement CT_956412_FDE_493024_06.pdf.PDF Disassembly Remove the two Date Wheel Keepers. I always start with the one holding the Date Jumper Spring in place. Sometimes the Date Jumper Spring can ping out of place, so be careful when removing the keeper plate above it. Here is a reference photo in case it moves before you see how it's properly seated. Next remove the Keepers and Date Wheel. Then remove the Date Jumper Spring, Motion and Calendar Work. This will leave only the Keyless Work; remove the Yoke and the Sliding Pinion only. We need to flip the movement over, and disassemble the IC Board before we can remove the rest of the Keyless Work. With the movement flipped over, remove the 3 screws holding the Coil Protector. Note for re-assembly the Gold Screw in the centre. Now that the Coil Protector is removed, GREAT care must be taken not to damage the exposed fine windings of the Coil. Then to remove the IC Board, simply remove the 2 remaining screws that hold it. Do this slowly and carefully, as you do not want to slip off the screw and damage this delicate circuit. The same level of care needs to be taken when removing the IC Board from the Main Plate. Take your time and carefully lift it off and store it immediately out of harms way. Next remove the black Insulator Block, and Battery Insulator. This will expose the Setting Lever Spring Clip, which will enable you to remove the rest of the Keyless Work. To remove the Setting Lever Spring Clip, place both points of your tweezers on the locations where I've placed the stars and gently push down on the spring. Then with a piece of Pegwood, push the spring in the direction of the arrow until it moves to the larger opening slot. This will now allow the Setting Lever to be removed, along with the rest of the Keyless Work. Next remove the Stop Lever and Switch, and remove the one screw holding the Train Bridge in place. Then carefully remove the Gear Train and the Rotor. The movement is now completely stripped and ready for inspection and cleaning. There are some parts that you do not place in the parts cleaner, they are as follows: Date Ring Rotor IC Board The rest should be demagnetized prior to cleaning to avoid any metal particles in your cleaning solution from sticking to your parts. When cleaning I also including the Insulator Block, and Battery Insulator in the basket, normal watch cleaning solutions do not harm these items and it is essential they are completely clean to provide the best insulation possible. The Rotor should be cleaned by use of Rodico. As you can see from the picture below, it's surprising the dirt and old oil this will remove ... and it is sufficient cleaning for the Rotor. I hope this has been a help to you, and I will post the assembly procedure later today, if time permits.
  11. Since I was working on the Landeron 48 with wrong dial, from which I used the case and a Landeron 151 and correct dial to make a new watch, I saw this Landeron 248 sitting in the drawer at my desk and devided to finally tackle the issue it had: a slipping mainspring. I documented the disassembly of the movement vith 3 videos, the first of which is here below: Hope you enjoy
  12. I have an Omega Speedmaster 1861 which is gaining 55-60 seconds per day. How can you tell if the watch needs a service or just regulating? I have checked the watch for magnetism and it is not magnetised. The watch was originally purchased in 2010. I only wear the watch a few times per month. I have made a short video of the watch on a Timegrapher . Any suggestions / comments would be most appreciated.
  13. Kienzle Markant Pocketwatch Service One of my Mum's friends dropped off a pocket watch for me to service. It was her father's watch, and she used it all through her nursing career: so it held quite some sentimental value to her. She told my Mum that it did run; but only for a few minutes and then stopped, unless the crown was moved. It's a German made Kienzie Markant. I popped the back off and the movement and saw that it was VERY dry, but in good condition. First thing I notice was the stamping .... Zero (0) Jewels - Unadjusted. So this thing is no RR Standard Hamilton; but none the less a nice little project, and one that will make my Mum's friend happy :) The front was also removable via a case blade, and since the Main Plate was riveted to the case is required to be removed in order to service this movement. With the hands removed, the dial was next. It is secured by two screws on the face. Motion Work is a very basic setup. So I removed the Cannon Pinion and moved to the back of the movement. While inspecting this movement carefully, as this is my first attempt at a pocket watch, I noticed a few things that I'd never seen before... Firstly, the timing adjustment is done by a sort of jack screw arrangement. (Note: The two large screws for securing the Balance, and a smaller "Jacking Screw" to adjust the timing.) Secondly, the Fork arrangement was also something new to me. Posts instead of Pallets to engage the escapement. Here's another view the Fork removed. So I removed the tension from the Mainspring, and removed the Balance and Fork. I was a little nervous removing the Bridge, as it's a 3/4 Bridge and I couldn't see the layout of this movement, and since this is a very new style of movement to me I wanted to take reference photos. Well my nervousness was justified, and EVERYTHING lifted out with the Bridge!! ACk!! :startle: Again, something new to me was the layout of the Keyless Work. It's a rather clever rocking pinion system. Rock one way and the Mainspring is wound, rock the other and you engage the Motion Work. Thankfully the Click Screw was marked as a left-hand thread ... Note the extra stripes either side of the Driver Slot. Movement is fully stripped and ready for a bath :) Here's that nasty 3/4 Bridge that stopped me taking reference photos of the Gear Train Layout. Once all the parts were clean, it's time to get this thing back together .... Gulp! :lolu: My Heavenly Father has gifted me with skill and cunning when working with watches, and I thank and praise him for it!! To assemble the Gear Train, I placed them upside down on the 3/4 Bridge, and then lowered the Main Plate on top of them. This made the alignment of the train and pivots a breeze. I then flipped it back over, and with a few gentle wiggles and very slight pressure on the Bridge, everything was in place. I replaced the Second Wheel, and the Spring Keeper. Refitted the Motion Work and Cannon Pinion. Then the Fork and Balance. Adjusted, fitted the Dial and Hands, and Re-Cased. The Kienzie Markant is now running smoothly and continuously. It was great fun to work on, and I hope you enjoyed the walkthrough. PS. when held to the ear, the ticking sounds like an old grandfather clock :P Gotta love dem pocket watches!!

  14. Also merely to gather more and more experience, I bought two ETA 2472 over the time for little money on ebay. I think they were less than 20 EUR each. I already worked on one which did not work, since one of the escapement wheel pivots was sheared off. I demagnetized the movement which I hadn't worked on earlier and put on the timegrapher. The result is excellent, especially since the beat error is zero. I did not adjust anything yet. For the first movement I ordered a replacement escapement wheel on ebay. Unfortunately the seller didn't pack it properly. This is the result: A bent wheel. I was able to fix it with this trueing caliper which I also got for very little money on ebay. This is the result of the movement with the repaired escapement wheel. BTW the seller of the bent wheel refunded me and apologized. He asked me to keep the bent part. The movement which I will work on now has a problem in the date mechanism. The date just doesn't move after midnight. I assume it's a problem of lubrication. Let's see. I will now disassemble the movement. I will use the order that ETA suggests on the 2824, @bobm12, this thread is only for you Cheers Alexander
  15. Has anyone had the experience of doing a full service on this movement with a tutorial or video?
  16. ETA Caliber 2540 Complete Service Walkthrough Looking for more movements that would expand my training scope. I found this one on the Fleabay: an ETA 2540. It's a "New Old Stock (NOS)" replacement movement, therefore it's not cased, and came with no hands. As there are many ladies watches, especially vintage ones, that are very small, this was my next obvious choice of movement to work on. As you can see next to my thumb nail, it's quite a small and compact movement indeed. Disassembly First remove the Hour Wheel, and leave the tension spring in place. Remove the Minute Wheel, Canon Pinion with Drive Wheel, and the Winding Pinion. The Canon Pinion on this movement isn't the standard fiction fit, it is a "Circlip" type fitting with the Driving Wheel. Therefore no pinion puller is required on this movement. Below is a reference photo. The motion work is now removed, so it's time to turn the movement over. With the Movement turned over, release all tension from the Mainspring. Remove the Balance. Remove the Pallet Cock and Fork. Remove the Crown Wheel and Ratchet. Remove the Click and Click Spring, then the Barrel Bridge. Here is a reference Photo of the Click Spring. Remove the Train Bridge. Remove the Second Wheel, Third Wheel, Intermediate Wheel, Escape Wheel and lastly the Barrel. Finally turn the movement back over, and complete the disassembly by removing the Keyless Work. Remove the Setting Lever Spring. Remove the Yoke Spring and then the Yoke. Then remove the flip the movement over and unscrew the Setting Lever Screw. Pull the Stem out and the Clutch Wheel and Winding Pinion will fall out. Here is a reference photo of the Yoke Spring. Disassembly is now complete.
  17. Service of a Seiko 6106 Movement Sorry I have been slack posting movements I've serviced at home, but work has been busy, and the movements I've been servicing are not that different than what I've already posted ... just more of the same. Well, I got another one of my Mum's friends who asked if I could repair their watch that was given to him on his wedding day by his wife: who has now sadly passed away :( Of course I said YES!! And it turned out to be a lovely old Seiko; but a little worse for wear :unsure: The hands had fallen off, and the plexiglass was so scratched you could hardly read the dial. After opening up the caseback, there was evidence of corrosion starting to set in ... but thankfully it was caught in time. Here's what the intact movement looks like. Once the automatic works were removed, it was obvious this poor old thing has never seen a service since it was purchased in 1974. Very dirty, and very dry. This movement has a complex keyless works which included a pusher for rapid date change, so before I started removing the dial side, I pulled the Balance and Pallet Fork ... just to be sure to be sure :) Notice how dirty the movement is from this angle as well. Ok, on to the dial side, to remove the calendar work and the Keyless work. Calendar work is pretty much like all Seiko's ... minus that annoying phillipshead screw, thank the Lord! Here's a picture of the Keyless work, with the incorporated pusher system for date change. More of a close-up of the pusher arm There is also a large spring for the pusher mechanism Once that was all disassembled, it was back to the Train Gears and Mainspring. Notice this movement also has a hack that stops the Train Gears; instead of the Balance ... all very interesting :) And for my good mate Bob ... here's the picie of the Automatic work mate :P Look how dirty and nasty the Eccentric Bearing is ... Ewwwww! Here she is coming back together after a long bath in the suds Lookin much better! I polished the case, and spent about 15mins with Ploywatch trying to polishing all the scratches out of the glass ... but it was just too far gone :( Still at least you can read the Dial now :P Off to the Timegrapher and in typical Seiko fashion, once cleaned it purrs :D Hope you enjoyed this post, and I'll try to post more often guys.
  18. Seiko 7S26A Complete Service Background I have a good friend, a brother in Christ Jesus, who I've known for many years. He knows I've embarked on retraining myself for a new career in Watchmaking, and seen my first two restored watches. He told me that his old faithful Seiko 5, which he's worn everyday for 12 years, has recently had issues. Occasionally it will advance rapidly in time (up to an hour in a few seconds) and then just keep ticking away normally. I told him I'd be happy to take a look at it, and put it on my ACEtimer Timegrapher. The pattern on the screen looked like a B-52 drop in Nam (stupid me forgot to take a photo), and I told him that his watch definitely needed an inspection and service. So started my research on what the problem might be. After reading a "Practical Watchmaking", and the many forums that I've read, I was pretty sure it was the Pallet Fork ... either very dirty or damaged stones, or a broken/damaged fork pivot. So onward to the service... Disassembly One unusual aspect of this watch is the crown ... or lack there of, more to the point. I suppose since this is an automatic watch, they thought it didn't need to be wound. This watch also has a display back, so extra special care not to mark any of the plates, or damage screw heads! The first issue you'll face when working on a 7S26A Movement, is how to get the stem out! It isn't obvious at all, and there is a little trick. The crown needs to be pushed all the way in to expose the push plate (it is hidden in the other crown positions). I took this photo once the movement was out to best illustrate where to push. Remove the Hands, Dial and Oscillating Weight (2.0mm Screwdriver). Gently lever up one end of the circlip and carefully work your way around. You then should be able to raise the circlip up the length of the shaft without it pinging off. Remove the Day Wheel and the four screws holding the Date Dial Guard. (Use a 1.40mm Screwdriver, and this driver is good of all the screws from now on; bar one.) NOTE ORANGE ARROW: Seiko Special Tool needed for the 0.98mm Philipshead Screw (Part Number: S-921) I had to journey down to my nearest Seiko Distributor and grab one ... cost was AU$24.00 Here's a closer look at the troublesome screw. Remove Date Jumper, and note that the Date Drivewheel lips over the top of the plate. Remove all the motion work, and pull the Cannon Pinion Remove the tension from the Mainspring. Remove the Ratchet Wheel and the Second Reduction Wheel and Pinion. (remember the Reduction Wheel has a reverse thread) Unscrew the Balance Cock and remove the Balance. Also unscrew the Pellet Cock and remove the Pellet Fork. BINGO! Found the problem with my friends watch. The top pivot on the fork is broken. Easy fix with a replacement fork :) Remove the Barrel/Train Wheel Bridge Remove the Click, then the Barrel. Remove the Fourth Wheel, Third Wheel and Escapement. Unscrew the Centre Wheel Bridge and remove the Centre Wheel Now to the Keyless Work. Remove the Setting Lever Spring Remove the Yoke and the Setting Lever Pull the Stem out, and the Clutch and Intermediate Wheel will fall away. Lastly, pull the black plastic location ring off. ... and now it's bath time!!! I hope this has been of help to you guys. I'll post the Assembly steps in this thread tomorrow morning.
  19. Miyota Automatic Service - "Three Screws to Rule Them All" Now for something completely different, a Japanese Automatic from Miyota. This is a budget driver's watch from a fashion brand called Scorpion, and I had no idea what I'd find when I removed the caseback :huh: Whatever! I just wanna work on watch movements, increase my knowledge, and the repertoire of movements I've had experience with. It's also a blessing to post these to help people with reference photos and walkthrough of various movements. When put on the timegrapher, it was quickly obvious that this movement was not running well at all. Extremely low amplitude, high beat error, and a graph that looks like the pepper in your mash potatoes :P Well, it happened to be a Miyota Automatic Movement ... I have no idea of the caliber, as there are no stampings on any of the plate ... beside the brand name. Once removed from the case, I pulled the Hands... ...and then the Dial. After that, I flipped it over and removed the oscillating weight to get a better look at the movement itself. Notice anything scary about this already?? There are only 3 screws holding the complete movement together!! :o Ack!! Visions of the Seiko 5J22A Kinetic "Auto Relay" , with it's 9 pivot gear train plate flashed before my eyes!! This was NOT going to be fun putting back together :P But I do so love a challenge. As per usual, I removed the tension from the Mainspring, and removed the Balance and Fork. Note: The red arrow is pointing to a very thin spring which you pull back to disengage the Click. Here's a closer reference photo of it after I'd pulled the plate off So as the title says ... Three Screws to Rule Them All .... Bam! The whole movement has to be located into ONE plate, that's only held by three screws ... this is not Rolex quality gentlemen ^_^ After tipping the movement up-side-down and telling the complete movement fall onto the desk (just kidding), you are left with only the Centre Wheel. Once the Centre Wheel Bridge was removed, the fault with the movement running so badly came to light ... RUST on the lower piviot! Rust also on the Pinion Over to the Calendar and Keyless Work ... looking way over complicated for a simple Date Wheel, as all the springs are there for a day complications as well; minus just the Day Wheel :( ... Gotta love cheap movements. Reference photos of the Keyless Work. One last thing to note with this movement. The setting lever is riveted into the Main Plate, so it's not able to be removed. Well this little gem is in the Watch Cleaner, and I've got a few weekend chores to do, so I'll put it back together tonight and post the results later. Hope you enjoyed this write-up, and got a few giggles out of it as well :)
  20. Hi fellow watch friends, back again with another service for ya :) This one is a woman's bracelet watch that were popular 20-30 years ago ... your Mum probably had/has one of these. Now when I say this movement is small, I mean it's small ... I don't think I used a driver over 0.8mm on it. And being small doesn't mean they are more difficult, but you need good optics to make working on them enjoyable. ...yes, that's my thumb! I've worked on a few of these now, and they commonly are held in the Caseback as seen below. So be careful when removing them so as you don't damage the Dial or Hands. Once I had removed the movement from the Caseback, I saw my very first indication that this job wasn't going to be a quick service. Notice that Ratchet Screw? Here's a close-up of it. I see this way too much servicing watches, and it's become my pet hate. King Kong has worked on it before me, and has tighten every screw up to 50 foot/pound ... Arrghhh!! :growl: Needless to say, when it came to removing nearly all the screws, it was a battle; but the battle was lost with the Ratchet Screw and I was unable to undo it (even after applying some heat) and it seared off ... so 1x Barrel Abor and 1x Ratchet Screw to be ordered. My mentor and trainer is a 78 year old master watch maker, and the VERY first thing he impressed on me is not to over tighten screws. "We are not torqueing down head bolts on a V8, these threads are less an a millimeter across ... use a light touch son.", is what he told me. I'm sure some old hands here can also add their words on wisdom on this matter. Ok, end of rant :P Back to the service... Firstly, I removed the Hands and Dial, and as per normal with this style of watch, there was moisture ingress. These types of watches aren't very well sealed from the elements (no Caseback Seal, no Stem Seal), so you'll nearly always encounter some rust removal in the servicing. This looked fairly light corrosion, and I was hoping it hadn't gone further into the movement. Here's one of the reasons this watch stopped. Heavy corrosion around the lower Barrel Arbor pivot. Next, as always, I removed any tension from the Mainspring, and removed the Balance and Pallets. Next I removed the Ratchet (shearing the screw in the process), Crown Wheel, and then removed the Barrel Bridge. As you can see, very old, dry, and dirty grease. Main Plate looked in good shape, which saves a LOT of work ... if this thing is covered in rust you've got your work cut out for you. Pulled the Cannon Pinion, and happily it wasn't ceased, but also is still a good fiction fit. Here's a reference photo of the Gear Train setup once the Bridge is removed. Again all looks good and no damage to any of the pivots or jewels. Stem, Clutch, and Setting wheel are filthy and typical of a non-sealed movement of this age. On to the Keyless Work, and unfortunately rust had gotten in here too. The Yoke Spring was the worst of it, but with a little time and effort, it cleaned up fine. Setting Lever needed a little work too :unsure: So the parts are in the cleaner, having a bath for the first time in 20+ years. And I've emailed the good people at Old Swiss Watch to get a new Arbor and Ratchet Screw. I'll have the assembly post up as soon as the parts arrive, and get this little movement tickin like new! Thanks for reading my post, and I hope this helps and was informative. :)
  21. I have an Omega Speedmaster Cal. 1861 purchased in 2007. I haven't yet had it serviced and I am starting to feel some guilt. However, the watch is keeping +2 over 24 hours so I am very happy with that and it gets about a months wrist time a year. I am concerned because I don't want to interrupt what is essentially a good thing right now - I know this can't go on forever. Anyway, Omega repairers say every 5 years and as long as 10 years for a co-axiel like the SMP or PO. Anyway can I get your thoughts on it.
  22. So, I'm new and love disassembling things. I have an 18/0s ladies waltham watch I'm about to tear into to. So at what point do I just clean the assembled watch? This is a very small watch. I just don't want to be spinning my wheels trying to take apart and reassemble something even the pros don't do.
  23. ETA F05-111 Service Walkthrough "The Workhorse Of Midrange Quartz" Moving on from the ETA 955.412 service, another common quartz movement, this time found in mid-range quartz watches, is the F05 111. It doesn't have the build quality of the 955/6 model; but it's still a very robust movement, and able to be serviced. In saying that, this movement is rarely serviced by a professional watchmaker due to the low cost of a replacement movement. Personally, I think it's sad we live in such a throw-away society, and are slowly loosing the skills and confidence to performance maintenance at home. So if you've got the tools and confidence to service this movement at home, do it, and save yourself $$$. Service Manual for the F05 111 Movement ETAF05.111.pdf We will first start with the Motion Work and Calendar Work. Remove the three screws holding the Cover Plate. You will see that this also has the Date Jumper Spring incorporated into it. Next remove the Hour Wheel, and the Date Indicator Driving Wheel. Note too that there is no quick date change on this movement. Remove the Minute Train Bridge, Minute Wheel, Canon Pinion and the Sliding Pinion And that's it for this basic movement on the dial side. Flip the movement over and we'll begin on the drive side Remove the three screws marked below and lift out the Electronic Module Cover. Next remove the two remaining screws that hold the Gear Train Bridge. As you can see with plastic wheels, this is not up to the same quality and finish as the 955/6 movement. Remove the Second Wheel, Intermediate Wheel, and the Rotor I would not recommend removing the Third Wheel at this time as the IC Board circuits are directly above it, and there is no point risking damage to it. To remove the IC Board, gentle lever up the where the location pin goes through the board just at the end of the Quartz Crystal housing. This pin is often firmly pegged to the board and must be lifted up first. This will loosen the board away from the Main Plate. Then gentle lift out the IC Board by sticking a piece of Rodico to the mark position below and lifting out. This will avoid any damage to the circuit or Coil. Now that the IC Board has been removed, access for removal of the Third Wheel is risk free. You can also remove the Insulating Block at this time. This is also the time to remove the Battery Insulator, but this being just a spare movement I own, it's been used elsewhere ... sorry :unsure: The Keyless Work is now exposed, and is a very basic setup, being held only with 1 shouldered screw. The movement is now completely stripped and ready for cleaning. All the parts can go in for cleaning EXCEPT the following Date Ring Rotor IC Board PLEASE NOTE: Due to most of the wheels being plastic, be careful when you come to the heating/drying stage if you are using an Elma/Pearl Parts Cleaner. Make sure the basket is high up in the drying cylinder and ONLY RUN FOR 11 MINUTES MAXIUM ... too much heat isn't good for those little plastic wheels. I hope this has been fun and edifying to read. I'll post the assembly procedures latter tonight after dinner ... my tummy is talking to me :)
  24. Cyma R-425 Service "Things that go bump in the night" Here's something a little different, that I hope you all find enjoyable to follow. A Bump Automatic by Cyma ... the R-425 Movement. This watch was purchased by my Uncle in Sierra Leone back in the 60's, in his wilder younger years. The automatic winding feature of this movement using a "Bump" system, which these days is a very rare method of winding the mainspring As you may have noticed in the first picture of the Dial, the numbers on the Date Wheel have been removed. Once I pulled off the Dial I could see that the number have peeled off the Date Wheel and adhered to the back of the Dial. I have no idea how this happened :wacko: One possible explanation is that the previous person who serviced this watch cleaned the Date Wheel with something that over time loosened the paint and glued it to the back of the Dial ... who knows :blink: As you can see, whatever they used completely stripped the painted ... absolutely nothing remained on the Date Wheel. Anyhooooo, on with the disassembly ... The plate that secures the Date Wheel on this movement is a full plate, held by 2 screws. Once removed we can see the Keyless Work and the Calendar Work. All very standard looking with no surprises. Here's a closer reference photo of the Keyless work. Once the Calendar and Keyless Work was removed I flipped the movement over and removed the Bump Weight. The Automatic Gear Train Bridge was the next to be removed. Once the bridge was removed the Automatic Work is revealed. Notice the fine spring system for the Ratchet Arm of the Automatic Work ... this same spring system is used throughout I removed the plate that holds the Auto Work revealing the next layer containing the Barrel Bridge and Gear Train Bridge. The Gear Train is your typical looking train except for the having the Second Wheel come up through the plate and running to a long fine pinion. Very interesting and you rarely see this type of complexity in your average movement these days. The shock system for the Balance is one I'm not familiar with and would appreciate some input from the old hands on how to clean and oil this correctly. And yes, the Balance is 18ct Gold ... very purrety B) Here are all the parts after cleaning ... LOTS of plates in this movement, they fill half the parts tray :P Stay tuned for the assembly!! And I may have a solution for the Date Wheel ... :ph34r:
  25. Ok, I think I will open a can of worms, but here goes: How do you oil the pallet jewels? I know there are several ways to do it. I would be very thankful if some reasoning or pros/cons would be presented. And also, how could one check if they are properly oiled. I think the correct oiling of the pallet jewels is one of the critical things in watch servicing. Thank you, Bogdan p.s. I saw Mark's way... don't think it's the only one. I also expect him to have something to say in this topic :) if he finds the time
