  1. Hello everyone, I found myself in a really embarrassing situation. A member of our distant family had an accident many years ago and has since lost his sight. Until now, he used a watch with braille. Well, they broke, and as the first reason, since it's a quartz watch, I evaluated that it was the battery, it was replaced, but it still didn't work. So I said to myself that I will take them apart, clean them as much as I can and I will see. And here the problem arose. I lost a small screw during assembly. I mean a really small one and I have no idea how to buy such a screw or if it can be bought at all. The movement in question is eta 955.112 and it is divided into two-hand and three-hand movement. I have the two-hand movement, the one without the second hand, and the lost screw goes in place of the second hand. Its purpose is to hold the hands in place as people with visual impairments have to feel them. Could someone please advise me on what kind of log goes into it and where I could buy it? It is a very unpleasant situation for me because the guy has been through a lot and I would not like to return an even more broken watch to him. I was still thinking about having them repaired by a watchmaker, but when I inquired, it would be quite expensive, I would rather solve it with the screw if possible. Thank you in advance for your advice
  2. Looking for some help, my friend had an issue with his watch having water enter the movement. It has stopped working and I fear the movement could be fried. Just in case this worst case scenario plays out I was looking at new movements. The movement is an ETA (Tag) 955.112. I looked on CousinsUK and they say it is a discontinued movement. They only have the version without the seconds hand for sale. Does anyone know the correct movement to replace the ETA 955.112 with? I did see one site state that the ETA F06.111 was the replacement, but I'm not sure I trust the source enough to order one without checking here first. Also it looks like the crystal gasket may be to blame, can anyone point me in the right direction for a replacement? It is a Tag Kirium, but the part numbers have been worn off that case back. I guess this would also imply that the 955.114 could also replace the 955.112??
  3. I'm looking for any instructions for this watch to reset everything after a battery change. It's some complex series of presses on the 3 pushers and 1 crown but I can't remember the sequence and I've lost the instruction sheet that I had. Any help would be appreciated
  4. I have here one of my late father's watches, a Rectangular faced watch measuring 3/4" wide x 1" tall. It is made with bracelet and a clasp but it does not look like a deployant or deployment clasp. To get the watch case back off I had to open the bracelet and I can't remember the sequence to get it back together. I got it running but the band probably needs dissassembly from the watch and an ultrasonci cleaning. Would someone know the name of this style of clasp? I've no had much luck with google. Thanks in advance, I thin that since joining this forum a few months ago I have now sucessfully changed the batteries in 11 watches and only a couple to go, before every watch in our house is working again. The next thing I want to learn (after learning about this bracelet / clasp LOL) is how to clean a watch properly. You guys are very resourceful. THANK YOU Mark
  5. Hello everyone, Today my partner in crime is the little guy below. History unknown. I purchased it when I was living in Japan. The battery left inside for a long time I think and was in leaked situation. I took it to a watch maker and he told me that he cannot get any readings so it may be a bad coil or something else and refused to deal with it. I took it apart to show you and ask your advice. I don't know how to troubleshoot a quartz movements (sounds like I know mechanical ones ) so where I should begin to diagnose? Inserted a battery, no sign of any life. Mechanical parts moving without any issues, also the date changes flawlessly. There is one thing though, I marked on the photo below, when I was cleaning inner part, I found some black, plastic crumbled parts probably deteriorated because the battery chemicals and the rest of it was under that brass screw (still some stuck there), probably it is a non-conductive material to prevent some shorting! The movement number on the dial is: For future newbies like myself, to remove the backing, you need to press the tiny triangle locking pins (2 of them is enough to let the back go off) shown below:
  6. Hello all, I required a movement to fit in a very small space and opted for the Hattori VX01. I am embarrassed to admit that I unsure how to keep the battery (379) in place. The metal arms either side don't look to me as if they are supposed to be levered up onto the battery, especially as one has the end angled down towards the movement. If anyone has worked with the VX01 or a similar movement I would very much appreciate the benefit of your knowledge.
  7. I am in the process of building a custom tester based on the Accutron 600 test set. I choose the 600 because I have a pristine 700 and dont mind hacking the 600. I like the test set because of the huge 25ua meter! I am designing a variable battery source using a miniature digital volt meter mounted on a 3D printed module that plugs into the hole in the 600 test set (where the leads are stored). This is not a "does everything" tester either. It will let me test for low and high battery voltages, and also test pulse current. The picture shows the current state of the module--basically got the 3D print done. The electronics will be trivial.
  8. I have an omega watch, the inside of the case is signed as is the movement, however I cannot find another one like it anywhere online. Has a Harley Ronda 3775 movement (signed Omega). Before I try and sell this I just want to make sure it's real. Seems strange to put a in decent quartz movement, have it signed inside the case and on the movement and be a fake, but since I can't find another like it I want to make sure. Any help is greatly appreciated!
  9. Hi all, newbie here. I guess I've ended up a bit of a watch fan with a bunch of watches in my current collection (pic below), plus a few others I've sold. I haven't done that much modding of my watches, just battery changes and realigning hands on a few occasions. But I did put together a Series One watch from buildyourownwatch.com a few years (which I've actually sold since). At some point I would like to get more into building my own design, but baby steps first Anyway, my Helgray Field Officer II watch has been a trusty daily beater for some time, with a quartz Ronda 515 movement. The battery ran out a few weeks ago, so I ordered a replacement, put it in - watch didn't restart? Tried with a different battery, nada. Both were new batteries in original packaging with expiry dates years in the future. After looking around I found a few others online saying they'd had similar experiences when replacing the battery on a Ronda 515 movement. Seems like the movement is prone to dying at battery replacement time. So after a bit of hunting around at specs and seeing what I could easily get a hold of locally, I decided to give an ETA F06.111 movement a go as a replacement (https://shopb2b.eta.ch/f06-111-f06.1111597973808.html). It's shows up on the ETA website as discontinued and replaced by F06.115, but I couldn't find that locally and there didn't seem to be much difference between them. There was a 0.5mm difference in stem to dial height from the F06.111 to Ronda 515, but hand sizes etc. were all the same, and the key deciding factor was a much better battery life - 68 months using a Renata 371, as opposed to 45 months for the 515. Good news - it all worked. Switched over the hands to the new movement - even with tweezers and a hand press, I still find fitting hands the fiddliest of all! The hands maybe did get a little beat up from pinging out of my tweezers so often. The second hand isn't perfectly aligned but maybe I'll have another go some other time on that. Seems to me there's a market for a simple watch hand-friendly clamp, with a fine x-y axis adjustment to line it up to the dial and press mechanism to fit hands accurately and softly. Also needed to switch the crown onto the new stem and cut it to fit. Once the stem is in the new movement, the crown does sit at a slight angle if you look closely from the side, due to the 0.5mm difference in stem to dial height between the movements, but the actual date/time mechanism etc all works fine. I have a Renata 395 battery on the way, which the ETA movement can take and ups the battery life to 94 months! A few pics, and the Field Officer back in the working collection
  10. Greetings all. I think I may have made a mistake in buying a GP watch that has the 641-875 quartz movement in it. It's a nice looking watch, with a very solid case, but I didn't find out about the caliber number until after I bought it. The seller did not have an image of the movement. Since I usually like GP movements, I thought it was worth a little gamble on getting it running, even if I had to clean it. After the auction ended I found out about these GP quartz movements that are impossible to get parts for, and that the dead ones usually need a circuit that is made of unobtainium. Since the watch had an old battery (Union Carbide brand) in it I figured that I might get lucky and get it running with a fresh battery. I wasn't counting on that happening since the guy who sold it was a watch guy. It would be hard to believe that he didn't at least try a new battery in there. Anyway, it didn't get it running. Does anyone know about these rather interesting old quartz movements? I believe it is from the late seventies perhaps? Is there any use in seeing if one of those quartz movement "spinners" could free things up? Unfortunately, it's not like GP provides technical info the way a company like ETA does, so if I take it apart I'll have to take a lot of images as I do. Anyway, any help on this is appreciated. Thanks ahead of time. Stay healthy, all. Cheers.
  11. Hi, I recently purchased a Seiko GMT Perpetual off eBay. The watch has a 8f56 Movement which is the high accuracy quartz movement. The watch was purchased with a low battery (indicated by the second hand ticking every 5 seconds). I've since replaced the battery and reset the perpetual calendar, the watch was working for about 3 hours and then just stopped. I've since tried to reset the perpetual calendar again and it doesn't do anything just completely dead. I recently went to a local watch repair shop and they said it would need a entirely new movement and would set me back £250 for it. It would however be done by Seiko not themselves. Any help is much appreciated.
  12. Cheers mates! Arkobugg are doing things he haven’t done before… This movement are dead, and I need a new one, how do I do this?? Where can I find one that fit??
  13. Hey everyone, I cant find out how to get this drown off and I've tried everything. The Miyota JS25 movement says PUSH and points to a hole which I've learned means this is where you press to reease the crown but I still can't get the crown out no matter which position the crown is in. I first tried with the crown all the way out then with it halfway in, then all the way in and haven't been able to get it out, please help.
  14. Hello, I recently reacquired a watch I had swapped off to a friend years ago, a Seiko 7t62-0am0 Asymmetry (I believe was the name). The watch is a quartz movement and is a chronograph. When I initially bought the watch (new) it was worn gently. When I traded off the piece it was to a dear friend who tucked it away in a box and essentially forgot about it until recently. I got the piece back a few weeks ago, had a battery installed at an AD and it worked normally. After arriving home, I put on the watch and it was functioning normally, except it stopped after about 30 or so minutes. I took it off thinking it was a faulty battery or connection, but when I looked at it the next day in the display case it was again working. After repeatedly wearing the watch and removing the watch when it would stop, I have come to believe that my body heat is causing some metal part to expand, thereby making the watch stop. Could this be the case? If so, what exactly is the issue (i.e., which part is the culprit)? *the photo is a stock photo of this model watch* Thank you in advance for your assistance. Respectfully, Dr. C. King
  15. Got quite a peculiar one at the moment, and it's something that I've never personally encountered before. The clients watch is an Armani AR5905; he thought he needed a new battery and so here I am, Upon taking the case-back off and placing a new battery in, I heard the circuit do the all so familiar whirring noise like it was springing back to life, however when I flipped it over it wasn't ticking. So I pulled the battery out and again put it back in, but what I noticed was that the whirring noise was only happening when the battery was halfway seated and thus not making full contact, and as soon as the battery was fully seated everything ceased. This time I put the battery in halfway and then flipped over the watch to see it working, and to my surprise the seconds sub-dial at the 6 position was spinning around wildly. However again stopped when the battery was fully inserted. Anybody have any ideas as to what is going on? I could upload a video if that would help.
  16. Hello all, I have a watch I would like to fix my self. It's made by TAWATEC, who is no longer in business. It's very similar to a Luminox and used TGS for lume. I will provide information to the best of my ability. Here is a link to some information about it. Here are a few pictures of the watch. I have had the watch since May of 2011. I had the battery replaced in Feb 2015 by a local shop. Less than a year later, I noticed that after taking a shower there was condensation under the crystal. I pulled the crown and left it sit to air out. After about a week I pushed the crown back in and the watch no longer worked. I wondered what caused it to leak. I then remembered I had to change the date on the watch a few days before condensation had got inside the watch. When I was trying to set the date I noticed that it was difficult to pull the crown out and it was more difficult to turn than usual. My guess was that the gasket/O-ring that is on the stem/crown was messed up and had ripped and water had entered that way. I left the watch sit for a year and used another watch as my daily driver. I'm hoping to get this one up and running again. So I recently decided to see if I could fix the watch myself. Here is what I have done and have figured out so far... I was able to remove the case back by removing the 4 Phillips screws. Visually inspecting the O-ring that seals the case back, everything looks good. The movement is a Ronda 515. The plastic ring that holds the movement inside the case says Ronda 515 # 6. I was able to remove the crown and stem. Looking towards the inside of the crown there was remnants of the O-ring. After clearing the remnants and putting the crown back in, the crown moves freely. I also found remnants if rubber on the front of the dial. After inspecting the battery, it looks to have leaked its electrolyte What I would like to do first is replace the O-Ring that's on the crown and put a new battery in it. If I then determine that the movement is damaged, I can replace it later. What do I need to do to figure out what size of O-ring I need for the crown? I can take pictures of the crown/stem if needed. I also have analog calipers to use that are in inches. Thanks for your time!
  17. Dear all, It's my first post here, please excuse if I post to the wrong sub-forum. I own a small collection of quartz and automatic watches and at least do most of the usual service myself. A friend of mine gave me an old watch she likes and asked me if I can change the battery. She told me it's around 25 years old and cheap but she likes the dial. It was a present by a french bank she worked for. All my watches are either press or screw down backs and I have never seen a watch like this. It seems that the only possible way to open the watch is the small plastic notch on the back. I tried to open it with quite some force but it didn't open. Do I overlook something, is there a special way to open it? I also got the original case. A note in it says in french that the battery is interchangeable. Already thanks for all your help! Best regards, Martin
  18. I agree with what you are saying completely. I plan to only keep the case and back and replace everything else. I would have loved to put a mechanical movement in the watch but I think it’s too small (33.9mm x 7.1mm). My plan is to have the case and back replated and have the back blanked of its manufacturers engraving so as I can have a blank canvas to have something engraved on it myself. I was hoping to get advice on what movements could be used and buy the parts ready for a watchmaker to assemble as like you said, I don’t want to ruin the watch. I’ve already started sourcing/ordering parts which was a little silly without any advice so I’ll post what I have ordered below (if rules permit me to do so?).
  19. 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
  20. Hi everyone, I was asked to take a look at a broken Nautica watch. I tried a fresh battery and fair enough, it doesn't run. Closer inspection revealed a broken part on the setting lever (???) (not sure this term applies to quartz movements, there are lots of parts in there that don't look like anything I'm used to). Turns out the movement is a Timex m649. So I looked around the usual places for a replacement: Otto Frei, cousinUK, Esslinger.... and the EvilBay but no luck. I's either not available or marked obsolete. I'm was hoping to find a chart with an equivalent movement or the new version of the movement but no luck. I'm trying to get watch to tick more than I want the indiglo function to work if that makes any difference (althought it comes from the dial, not the movement apparently). Would anybody have any idea what I could replace this movement with?
  21. My uncle bought this watch in 1991 and left me it in his will. I've been unable to find the same watch anywhere online so I was wondering if anyone could help me find out more about it?
  22. I am looking for a stem/crown for a Miyota quartz movement (see attached). Why does Miyota seldom write the movement's part number on the movement? Can anyone help? It goes inside a cheap Nelsonic LAX 766 watch.
  23. Good evening all, I am in the middle of repairing my Omega Seamaster Aqua Terra which houses an Omega 4564 Quartz movement. The second hand had appeared to have fallen off after I'd dropped the watch but after disassembling the watch it was clear that the second wheel pin had broken. Here comes the problem. Of course, being Omega I had anticipated getting parts from them would be impossible so I looked a little further and realised that the Omega 4564 uses an ETA E64.111 base. After looking around, I couldn't find anywhere that would sell the second wheel alone so without thinking I decided to order the E64.111 movement complete. The idea was to remove the second wheel from this new E64.111 and use it to replace the broken one on my Omega 4564... This is where you will all join me in face-palming...and I bet most of you will already know what's coming... The height is way off. So much so that it doesn't even manage to peer over the minute wheel when assembled. A real rookie mistake. Does anybody know know the height of the Omega 4564 second wheel pin? I'm finding it hard to get a precise measurement using the broken pieces. Also, if anybody has one spare (long shot) or knows where I can source one that'd be great! Has anybody worked on this movement before? I found the reassembly of the train wheel bridge particularly challenging on this one so if anyone has any tips or hacks for that I can remember for the future. Thanks in advance for any help. David
  24. I received this really nice Seiko 7T42-6A00 to service and the description was that the timer (yes, this particular 7Txx model has a timer also) was not working. After first inspection, actually I noticed that it had some more issues, among which the quickdate that was not working. I made a video presentation of this watch: I decided to strip down completely the movement since it apparently had never being serviced. A movement swap was just not an option... Opening the case no sign of damage was visible, although I did notice some very fine white dust, probably some acid liquid that had dried out. Removing the movement from the case, and inspecting it, showed indeed traces of dried up acid:
  25. As pe the title, here a small comparison video of my Seiko Quartz Chronographs from the 7Txx series. Enjoy!
