  1. Well, thanks to some help from a forum member, the Accutron is back in business. That ETA movement was indeed the correct one. The sweep second hand didn't fit, so the hand that came with the new movement was painted to match. Everything works perfectly! I definitely didn't baby this watch and it's had its share of abuse, I decided that the case needed a polish, and I'll be sure to treat it a bit more carefully moving forward. Thanks for the help!
  2. Hi Hendo, All good so welcome and carry on. I am a retired electronic engineer. Almost a self taught watch repairer. I still use de Carles Bible. Some watches find their way to me after their owners have been quoted a lot of money to fix them. I fix quartz as well but not Accutron and F300. There are some highly skilled people on this forum but I am not one of them. Regards, Mike.
  3. Thanks gentlemen! As to expense, well, I won this fully serviced on owner watch for the princely sum of $300! When I look at whats new out there for that it makes this one seem somewhat of a bargain I think. I got a better movement than in my Accutron for Accutron money! The deals are out there if you keep searching and don't just jump on the first thing you see. The week before I saw a similar one though in not as good condition and with no fresh service and I nearly went for it until I did some research and realized it had the movement replaced for a standard ESA one. Nothing wrong with that in terms of functionality as apart from the copper plates they are identical movements to the Omega but it was not an Omega movement and it went for pretty much the same as this one!
  4. Hi Max, Your precision engineering will stand you in good stead. Good luck with the project. I could not do that but an old friend who was a Swiss trained watchmaker and now gone taught me quite a lot of practical and theory. I just service and repair standard watches. Not big complications . I re-battery and fix quartz as well and the electronic`s are easy for me as I was an electronic engineer. All good wishes for your success in watchmaking, a very skilled business. There is a lot of expert knowledge on this site and use a copy of Practical Watch Repairing. de Carle. I consider it a bible on mechanical watches. The Accutron is detailed as well. Good wishes, ?Mike.

    Hi RJK, Your Bulova Accutron was the best tuning fork watch. I had an Omega F300 (not as good as the Bulova) I smashed it many years ago when a car pulled out and knocked me of my motorcycle. I escaped with hardly a scratch. Watch and bike were wrecked !!. Speak later.
  6. As someone who takes the view that if it's been assembled, it can be dissembled and therefore fixed, I make occasional forays into clocks and watches and have a reasonable set of tools. I've practised on a few Chinese movements for the skill building and entertainment, but I confess I wouldn't take any of my 'real' watches apart - off to the professional for those. I'm more likely to tackle a clock due to the scale. Strong preference for mechanical, although - putting chronometer definition aside - possibly my most 'accurate' watch is a Bulova Accutron, which I have rated down to around half a second a day over two months. Built an interesting rating circuit based on the usual piezo element, but not sure i'm willing to open a very good watch to do the adjusting! I do get a string of more modest value watches for inevitable battery and/or gasket replacement, case polishing and other minor fettling and maintenance. So, an enthusiastic amateur.
  7. Hi all, Since I haven't found an Accutron yet, I jumped on this vintage Timex Electric. It's far from a tuning fork movement but it's satisfying me for the interim. It had a neat calendar band with 7 changeable cards for the appropriate month. Runs great and looks sharp. I thought it was kind of unique; can't make out the serial number but I think is a '67 model/style 84. Not too familiar with thier Taxonomy. Sent from my SM-G920V using Tapatalk
  8. Hi, I'm a newby, so please be gentle! I have an early Accutron into which I need to fit a new crystal. I have a NOS crystal. I understand the principle of fitting a tension ring crystal with a press, but need to make a die to fit the crystal. Does anyone know (or can estimate) the optimum internal angle of the top die please? Secondly, on a slightly different subject, I have seen on this site discussions about recessed crystals and non-recessed crystal, but from what has been said I still don't really understand the difference. Could someone enlighten me further please? Thanks in anticipation. pcuk

  10. Hi all, It's been a while since I posted anything, I retired a year ago and have been busy working on our house and keeping busy with watches but haven't really had anything worth sharing until this week. Anyway I put an ad in the local paper looking to drum up a little business or maybe even buy some interesting watches. Yesterday I bought a box of assorted watches. Got two 18s Elgin pocket watches, one accutron, a handful of other watches and this Wakmann. As soon as I saw it I knew I was going to have it. I offered the guy who owned them $300 for the lot and he said $350 and I said Ok. The Wakmann doesn't run yet because the hairspring looks like a birds nest. I know Mark has a video about how to straighten out hairsprings and I have done a few but this is beyond me so I have ordered a balance complete from Jules Borel at what I thought was a very reasonable price. Hope you enjoy the pictures. I did take a close up of the movement ring because it looks as if someone used tar as a seal. I have put the movement back in the case just to show what the watch should look like when it's finished. Also see the tangled hairspring. I'm not sure what happened but the regulator arm was pushed into the center wheel so I'm guessing the wheel caught it.
  11. I've always loved watches and always wanted to collect them. Knowing That most of the watches I'm drawn too are well out of my reach, I never started collecting. I'd wear what ever Quartz someone might gift to me and once it was beat to hell I'd just toss it. At, 45 I decided to try and rebuild my first watch, another long time bucket list item. That was my 1968 Bulova Oceanographer that I picked up at an estate sale for $10 purely by chance. After that one I had intentions of finding, fixing, and selling vintage watches. That was back in January. I've run into a slight twist in the plan though. After fixing and wearing for a day or two, I can't bring myself to sell them. With that said, I have now become a collector. Here is my modest collection that I have gotten much enjoyment from. 1968 Bulova Oceanographer 1976 Bulova Accutron 1975 Timex Automatic Early 90's Zarja 3105 Early to mid 89's Vostok Amphibian Vostok Kommandirski (unknown age) Sent from my iPhone using Tapatalk
  12. How many times have I been asked that question ? In all honesty , I don't know . From Rolex to Timex , I like them all . I guess it's kinda like being a parent ,...you don't have a favorite child . I wake up every day and try to figure out what it's going to be . I usually will wear about 4 watches a day so I can check to see if they are operating properly , or if they may need maintenance . If it's a work day the answer is easy . I only have about 20 [nice] beaters to chose from . For casual every day wear , there are a few I might wear more than others . I guess I have acquired an attachment to some of the watches I have repaired that gave me more of a challenge ,...some more than others . So I will share those for starters..... First off is a Seiko 6139 chronograph I bought in parts and pieces . I paid $58 for it if memory serves me correctly . I had to figure how to put the puzzle together , then how to get it to run , and finally , how to make adjustments and tweak it so it worked as it was intended to run . Next is a Bulova Accutron Deep Sea diver with a tuning fork movement . I bought it at the swap meet for $140 not running . When I got it home and checked out the movement it was rusty and the parts were stuck together starting at the crown , stem , and gear for the rotating inner bezel . The movement was ruined and I had to gather a few movements to make one good operating movement . With the cost of buying the watch and parts I ended up spending around $200 . This was my first experience with Tuning Fork watches . The rest of the watches had their own little roadblocks to get around , which the greatest obstacle was finding sometimes obsolete parts . The Citizen Americas Cup watch is a good example of that . I now have 4 of them with 2 working . The other 3 watches in this group shot is a retro Seiko automatic , A vintage Croton Buccaneer that for some reason , even though it has a smaller watch case , I like it . And last in this group is a Germinal Voltaire , which with it's offset pinion , ended up being a small challenge figuring out how to dismantle it . I broke some parts on this watch and a donor and had to ask for help on this forum . Then tracking down the parts was fun . Now that I know where to get the parts I am working on my 2nd Germinal Voltaire as I write this . So Now , let me ask You ,...What is your favorite watch ?
  13. Beautiful watch. I have always enjoyed BULOVA watches, collecting and repairing them. I have probably 50 in my collection and hundreds of parts movements and thousands of individual parts. A BULOVA accutron was the first watch I ever purchased myself at 10 years old, and I also have both my grandfathers watches that are BULOVAs. Sent from my iPhone using Tapatalk
  14. +2.5 cheapo eyeglasses from poundshop, and another pair with 20X loupe stuck on with Rodico for setting up pre-position of Accutron fingers. I found using loupe as designed it steamed up all the time causing irritation and annoyance, just when you get the damned things aligned--you couldn't see 'em anymore. All normal dissassembly and reassembly done with just the eyeglasses. Parts examination done at 20x For Indexing I use a £5 cheapo Chinese microscope 100x I modded for the job. Indexing jewels look like two house-bricks on a circular sawblade Works for me!
  15. A week or two ago I read on a forum (I think it was this one, but I could be wrong) about an electrical mechanical watch they had repaired. This type of watch up until then I didn't know existed (How much I still have to learn). From what I understand these watches were very short lived in the 1970s and used an electrical circuit to energise a magnet to swing the balance and were just before quartz watches came into being. I'm aware of tuning fork watches like the Accutron, but know very little about these other electrical watches. Has anyone got a good resource they can point me at so I can read up on them more, or recommend a few brands / models to look out for to buy? At the moment I don't want any rare or super expensive ones, just some good ones to learn to work on. Thanks Tony
  16. I use these for small parts like Accutron index-wheels in the ultrasonic-- http://www.ebay.co.uk/itm/2ml-test-tube-sample-vials-container-with-snap-cap-x-25-Freepost-/120916343579?hash=item1c272cfb1b:g:8VkAAOSwPe1Tz5aQ The advantage is--being a sorta softish plastic, parts bouncing round due to the ultra dont get damaged as could be possible using a glass bottle/vial/beaker, being semi sealed you can use any cleaning fluid you like in them with just water in the ultrasonic tank keeping cleaner fluids costs down --Yup. I'm a cheapskate!
  17. I repaired a Accutron a year ago but I don't own one yet. All of my own Bolova's have Swiss movements. So I still want a older American made movement Bolova. Accutrons seem to fall victim to "free" battery changes. The one I fixed was a mess of corrosion from a busted gasket.
  18. Wow , If you are ready to attempt a service on a bellmatic my hat's off to you and I wish you good luck . I have never really been a Bellmatic fan , but it just so happens that I picked up a free donor yesterday that has broken parts but a beauty blue dial and the original band . This watch has seen better days , but i picked up a running watch, head only , that is the same case as the non-runner . I hope to get one nice runner from the 2 watches . I guess I was on a Bellmatics roll because I also picked up this Nice running specimen for a good price . It needs a new crystal that I am in the process of getting , but it has a coffin link Bracelet that I'm a sucker for . I have a coffin link on my Bulova Accutron Astronaut and I love it . Do you have the Bellmatic / 4006 tech sheet ? It's quite long and involved and you may want to study it before you start your project . If I'm not mistaken , the Seiko 66 morphed into the 6602 which tech sheets are also available . You can go to the Seiko Citizen Watch forum and find those tech sheets and many other things Seiko and Citizen .
  19. Howzit ramrod , 10 running and about 3 or 4 for in the works . I need complete balances with good coils for the 505 and complete contact springs for the 500's .Hard to get parts .There are donor movements for sale , and not cheap , but there's no guaranty on the parts being good ....Similar to Accutron donors . There are a couple more electrics I want to get and a few mechanicals of similar design . The problem is I started out with the more available , less expensive models . It's an uphill climb from here .
  20. Great video! I was given an Accutron recently and now I have a much better appreciation of its historical significance and technology.
  21. jdrichard ask how to clean an electric watch . I am going to start this thread by posting from the Hamilton Electric watch manual.... And from the Accutron 218 Service manual.... With the Hamilton electrics it is a normal service cleaning procedure , EXCEPT for the Balance wheel . The balance wheel has a coil attached that should not be subjected to harsh chemicals , alcohol , or petroleum based solvents . I am speaking of the coil itself . As for the rest of the components on the balance staff I use a hairspring cleaner applied with an eyedropper directly on the hairspring and a fine cosmetic or watercolor brush to clean it and then lay it on absorbent paper and use my blower to dry it . I also use the brush to clean the the other parts on the balance shaft ,...and there are quire a few little goodies on it , and use the hairspring cleaner or 91 percent Isopropyl alcohol .
  22. Howzit Shirley , Thanks for the kind offer of the service manual . I have a couple of versions . Some I found online , some in some watch repair books I have , and one really good one I bought online . Both the 500 and the 505 are pretty hard to get parts for . You can find donor parts for sale on ebay , but they are heavily sought after and expensive ., Most offerings say that the balance turns freely which is something you would look for in a mechanical watch , ...but the balance assembly has all the other parts on the shaft that have to be good to be usable . Also the 500 needs the plate with delicate trigger and contact springs . They get broken or knocked off very easily . I saw one of your posts where you mentioned you had Accutron parts . I will get around to sending you a PM to inquire about those parts soon , if that's OK ? Here is a pic of what the Everest looked like with the black band.... And here's a pic of what the Pegasus Model looks like . I just noticed that the pic didn't make it to the party in my original post .... Cheers , Louis
  23. Just as a note of interest, timekeepers like the Bulova Accutron were electro-mechanical devices. The oscillating mechanism (tuning fork) was connected mechanically to the hands with a solenoid and ratchet mechanism. What some people call an electronic time keeper has to do with the way the tuning fork oscillations are counted. It was known for many years that running a current into a quartz crystal would cause the crystal to vibrate. Since the vibrations occur on an atomic level they vibrate at a much faster rate. The problem was quartz crystals were too large to fit into a watch. Japanese engineers figured out how to reduce the size of the quartz crystal by machining it into the shape of a small tuning fork. This allowed a much faster vibration that was not practical to count mechanically. This problem was solved by using a digital counting register available in an integrated circuit. The circuit works by using a string of 16 flip flop circuits. A flip flop circuit is the electronic equivalent of a latched relay. Logically it does the same thing but on a practical level flip flops operate at a much faster rate. The upper time limit of a relay is based on the response of its mechanical components while the upper time limit of a flip flop is based on the speed of electricity. The first 15 elements of the register count the vibrations from 2^0(1) through 2^15(32,768). The next vibration moves the count to 2^16 which is used as a flag bit. At this point the register is reset and a polarity reversing circuit is triggered. This circuit provides the necessary pulse to drive a stepper motor. A stepper motor consists of a rotor with a north-south magnetic field projecting radially from the rotational axis. When an electromagnetic field is generated around the armature it rotates to the field of opposite polarity and stops. When the field is reversed the armature again moves and stops. The direction of rotation is controlled by making the path of one field longer than the other. The stepper motor is connected through a gear train (plastic gears) that drives the hands. david
  24. That second link is fascinating! I gotta save that one. This is my first exposure to the beta series. I've never heard of them before This Titus. I'll take a look at the movement tomorrow. I can say this about it: the second moved more smoothly than any of my other swissonics but it is NOT in the range of Accutron smooth. The ticks are barely perceptible. I should put up a video. So, I can assume that the dial says beta because it is a beta. Sent from my XT1585 using Tapatalk
