  1. 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
  2. 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.
  3. Hello, I'm new here and into watch/horology world as well. I recently tried to replace the dial on my 7750 watch. 1) Open the wathc case 2) removed rotor 3) removed stem (gentle push of remove stem pusher and pull the stem out) 4) removed the movement from the case 5) put movment to movement holder 6) removed hands 7) removed dial 8) put new dial 9) pressed the hands back, hovewer during setting it up I realized the movement is not running - even when I wind it up - it is solid/stable and not ticking at all.. Kind of out of ideas w
  4. 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 th
  5. To gain more experience I will now reassemble an ETA 2671 movement. This movement is taken from the watch of my wife a couple of months ago, and I screwed it up: destroyed the hairspring and also destroyed the spring click (434), which is a very delicate part. Very different from other movements I saw before. The watch of my wife came back to life after I bought a used entire 2671 and just replaced it. Now I have all the spares, and want to reassemble it. The pictures were taken before I learned how to do that. The new ones will be much better. Here are not too many
  6. Hello, I'm building a watch using a Sellita SW200 and I bought an ETA 2824 dial. The dial has four feet and so does my movement, but they don't line up, the ones on the dial are too far apart relative to the movement. I think if I cut off two feet I can make it fit but I'm not 100% sure. Is this a common scenario?
  7. Hello, I know this is a long shot but would anyone happen to have the technical sheet for the ETA 1164. I acquired this little beauty on ebay; a non-runner from the USA, which needs a lot of TLC. I've never tackled anything quite like this one but fancied the challenge. However, I'm not 100% sure yet whether the everything on the bottom plate under the dial is complete - can anyone confirm? The top plate however looks fine. The watch back is stamped "Seeland Watch Co. Swiss" - having looked it up, it appears Frederick Seeland was once CEO for IWC! Nice historical timepiece once I've resto
  8. 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 nu
  9. Service Walk Through – ETA 2893-1 / Hamilton Khaki: Part 1 - Disassembly This is part 1 of my service of a Hamilton Khaki – dual time zone automatic based on the ETA 2893-1 movement. I purchased the watch on eBay and it runs for a short time then stops. Looks like it could use a good cleaning. Note that the part numbers in the images and text are consistent with those found in the ETA technical document for this movement. Disassembly of this movement is quite straightforward. The only "special" tool you need would be an oscillating weight bolt tool - and you only need this if
  10. Hi all, I'm currently building a custom watch with an ETA 2892-2 movement. The movement is from an old Brietling. I managed to fix it and was working perfectly. I was in the process of putting it all together, was attaching the second hand and it suddenly stopped. I believe I may have used too much force. However, I have taken the watch apart again (about the 12th time!). I notice that when I move the hacking spring it stops as it should, but when I return it to the position that would usually allow the movement to move again it doesn't. I assumed I'd knocked something out of alignment, b
  11. Hello, I've been struggling for two evenings now to fit the train bridge on this ETA 2832. Every time it looks like all pivots are aligned through the jewel holes and I begin tightening the bridge, the wheels begin locking up. On closer examination, it looks to me like the 4th wheel is not seating flush against the centre tube as shown in one of my photos. I believe this because the pinion on the 4th wheel is higher than that of the escape wheel, and equally about the same measurement out between the 4th wheel and the 3rd wheel pinion, which is lower. It also looks like the 4th wheel is foulin
  12. Hello Mates! Im working on an ETA 2783, and suspect that the canon pinion is to tight against the lower wheel. So I have to make it a little bit more loose... Has anybody done this befor? And how it the best way to do this? Thanks A ETA type of Center Wheel/Cannon Pinion
  13. Cheers Mates!! Working on a Tudor Oyster Prince with ref no: 2081/4 with a ETA 2784 movment. Cleaned and inspected, all looks good, no sign of wear and tear on the main spring, no sharps bend, looks overall good. Noticed that there where some marks on the barrel wall. But that I have seen before witout any drama.... Oiled it , put togeher , goes like a dream..... but the the spring does not stick, it snaps over after 6,5 turns by crown. So the question is: Can I just replace the main spring? Can I just replace the main spring and do something with the barrel w
  14. Hi guys, I am having a hard time figuring out what KIF Elastor spring to order on cousins to replace a broken one I have in a Hamilton movement cal. 61. I cannot find any databases that have any info about this movement but I am wondering what the difference is between the elastor 3-2 and 3-3 (what do I measure??). Thanks for the help!! -Emil
  15. Hi there. Has anyone ever heard about an ETA E10.311 movement? I can find no info on it whatsoever. It's one of these LCD screen over dial watches. I am looking for the tech sheet on this. Thanks!!
  16. Hello! So I managed to invest in a used "Bergeon 2795 Nivaflex" Mainspring winder . IMHO the winder barrels are a bit too big for the inner loop of the mainsprings. So my question is, fo anyone who had both: What is the difference between "Bergeon Nivaflex" winders and "Bergeon ETA" winders, the latter being the one especially made for ETA calibers. Thank you! Bogdan

  18. Hi all, this is my first post here. I repair watches as a hobby, and usually work on my own watches. This particular watch, along with two others, were give to a friend of mine, by his father, about three days before he passed away recently. The three watches, hence have an emotional value to my friend, and so, I wanted to get them going again. I fixed the QMax (Replaced battery), Titan (PCB and Coil, new battery, glass), and am working on this Rolex now. Almost all Indicators of a genuine Rolex that I have read of online, are absent, hence making me believe its most definitely a fake. i.e. No
  19. Hi everyone, I recently got an amazing Hamilton Sea Cliff 3 watch from the early 70s powered by a handwound cal.61. I received the watch and it had not been serviced in a very long time. I serviced the watch but unfortunately used an oil pick that was too large to take the elastor shock absorbing spring out to get to the endstones. I accidentally broke one of the two levers off in the process and am now left with a functioning movement that I am afraid might become easily damaged by displacement of the endstones from small shocks. I have included a photo of the KIF Elastor spring below.
  20. Hi, Can anyone help? I have a watch case that will exactly fit an ETA7751 movement but I cannot source or afford the movement. So I am on the lookout for an equivalent movement but am new to this. Can anyone advise which I should go for? Thanks.
  21. Hi, Can anyone point me in the right direction to where I can economically buy a Valjoux ETA 7751 movement, dial, hands, day/date and moon phase dials? I am based in the U.K.
  22. Hello all! I got my hands on a 15j Unitas 6497, and I would like to case it: Could you provide any sources of 41mm or less cases? I found something on Ofrei (http://www.ofrei.com/page1494.html), but I was wondering if there wouldn't be any smaller cases that would fit a 6497? Thank you, Bogdan
  23. Hi guys, Was wondering if you could help identify this movement. It has rusted and needs replacing! Unfortunately, there is no codes on it. It looks very similar to a Rotary I have, but looks a little wider. Kind regards, Alan.
  24. I have dissembled, cleaned and reassembled my first movement—an ETA 980.163. With my lack of experience it took me about a month working off and on. It’s hard to appreciate just how small the parts are until one has to try to handle them and place them in the movement. Anyway, I assembled the watch and it runs (for now) I tried to be careful about keeping everything clean but I may have introduced more dirt than I cleaned out of the components/movement.I had a question about the order of reassembly. I used the ETA Technical Communication guide to assist me in remembering where the components w
  25. Evening all. Would anyone be able to tell me if the ratchet wheel from the Omega 2500c and the ETA 2892.A2 are the same? i've been having a look at cousins and the part for the Omega 2500c seems to be coming up as - Ratchet Wheel, Frederik Piquet 0021 31.020 priced at just over £14. However the Omega 2500c is based on the ETA 2892.A2 and the ratchet wheel for that is - Ratchet Wheel ( 415 ), ETA 2890 priced at £8.95 Its the Co-axial Movement. Thanks for any advice.
