  1. There are many technical reviews on the net for Seiko Spring Drive. I recall a very good one with detailed pictures which was done at an American horological academy few years ago, you should be able to find it with Google. The reason why there are no repair or service articles is that by one side the owners are unwilling to give the watch to anyone but Seiko, and on the other hand even competent watchmaker are unwilling to touch these, as they are unfamiliar with them and would not get parts from Seiko. In fact even Seiko service centers anywhere In the world will send to Japan the Grand Seiko, Credor or Spring Drive models given to them for service or repair.
  2. Seiko doesn't sell to individuals, but pretty much anyone can buy and even special order Seiko parts from Cousins UK, Borel, Boley, Star Time, etc. These material houses also manage to obtain many Swiss parts, plus the many they had is stock before the restriction. but as per previous link the issue is simple: Swatch group has a set and published policy of not providing parts other than to their Authorized Service Centers. Many other Swiss manufactures do the same Also, Swatch is limiting sales of certain ETA movements to companies of the same group. Seiko don't have such a parts restriction policy. They also have a subsidiary company, SII to provide complete mov.ts to OEMs.
  3. I don't think it different from any other Swiss watch, 250° is a pretty common standard. BTW, on our friendly forum it's considered polite to introduce oneself in the dedicated section before starting asking questions.

    A toolbox

    OMG another subject of the Unimat 3 and very well equipped nevertheless! I've got a SIEG C0 myself and become a bit fixated about. I'm learning with it, have many ideas About self-made accessories, which as noted do cost a good deal. I'm in contact with another well known enthusiast, maybe we should find a place to swap ideas and projects. BTW the wooden box is great, I left something similar behind when moved. But then got the below, it was filled with a million of plastic tubes for stems. If anyone wants some just let me know.
  5. Sorry, I wrongly assumed it was a retro-design new watch, it's not and not even automatic. Looks the same as the below, reportedly using Unitas 6300N. But the etching on the caseback of the OP indicated also makes me think it can't be that old. https://www.chrono24.com/atlantic/atlantic-worldmaster--id10259827.htm
  6. There are also suction cups specially made for this. I've never seen a report about their effectiveness.
  7. You've posted a broken HTML page, not the actual chart.
  8. And, Swiss regulations allows their watches to claim Swiss Made (that is the legal purpose of the small writing on the face) as long a percent of value or processing is respected. https://en.wikipedia.org/wiki/Swiss_made#60%_rule_for_Swiss-made_watches I believe that the strengthening mentioned in the above entry has been, in the end, approved recently. Incidentally, also Japan has similar regulation. For examples, the much loved Seiko SARB033 "Japan Domestic Market" case is made in China. Depending on what one consider an in-house movement, IWC may or may not qualify into that market (and marketing) industry segment. These are really the type of endless debates one can read on WUS.

  10. Some crystals, like the one that is in the video and owned by the OP have absolutely no lip to grab with a lifter. So there is no other choice. Remember that our Mark is not in the business of teaching how to damage watches, but exactly the opposite.
  11. Not surprisingly, an ETA 2824-2. https://www.atlantic-watches.ch/en/shop/retro-vintage/worldmaster-original/2355/worldmaster-original?c=80 But a price of RON 125, or €26 seems too good to be true.
  12. What is an "adjustable escapement"? Even the cheapest mov.t can be rate regulated, while adjustment is a sort of obscure art which if you ask about, you will be told that "starts at the mainspring". Whatever that means
  13. Certainly is not ORIS only that does this, have a read below. Since mechanical wristwatches moved from being a common and necessary items to luxury and fashion the Swiss and Japanese will take all the money they can,
  14. May I ask, how do you currently clean watch parts? Which advantages do you expect from an old machine, beside the fun spent on many days of refurbishing and parts searching?
  15. That is, when you can find parts, and when the manufacturer is willing to sell them to independent watchmakers. Which exclude all the Swatch group, Rolex, Omega, and the Richemont brands. BTW, in the snippet you posted above there are at least four translations errors for my language alone. This is not a perfect world, repairers have bigger problems that parts names.
  16. Main parts names are consistent, but for complicated and "different" movements there are parts without a standard name. And sometime you see of use different names, e.g. bridge where another would say cock. That consideration about English, in which we have many books, although not many service sheets come from American or British manufacturers. Then of course the native technical languages for Swiss watches are French and German, so sometime you see a less than perfect english translation. Finally, also Spanish and Italian have a special set of horological terminology that in most cases, but not always, is derived by French. So there is nothing weird in wanting to know the proper names of parts, after which you're ready to start learning the name in other languages...
  17. Check this comprehensive topic: Also, please post repair question in the dedicated section: "Watch Repair help and Advice".
  18. That's exactly the indication of that being the setting lever you need to push.
  19. JDM.. Hehe.. To appreciate others you can use the like button on the bottom right of any posting.
  20. A faceted crystal has ..faces but not a lip. Seiko did not use glue often, and the crystal will not leave by pushing with a thumb. Fortunately, Seiko helps watch repairers by classifying and documenting the case construction, here we have an "A" as stamped on the case back. Attached the guide. A good discussion is at https://www.plus9time.com/seiko-case-back-information BTW, I recommend the OP to use the "Watch Repairs Help & Advice" section when it's repair question like this. One advantage is that there answers can be rated and marked as resolving. 1982.03 Seiko Case Servicing Guide.pdf
  21. Water Resistant 30 meters, I think that is a snap back case. See if there is slot to start prying in between lugs, otherwise see if you can (slowly and carefully) lever on top of the arches.
  22. Thanks david. So, browsing Bergeon's .website one can see the 1766 "Geneva pattern" model which was copied by the Chinese since 60s. I don;t know how much it cost but I have no tool envy towards it.
  23. Assuming they resumed activity with Japanese ownership, that is Dixi, of La Locle. http://www.lathes.co.uk/dixilathe/ I agree that both lathes can be used to make parts, how they are on the opposite extremes of technical and market segments. A Bergeon complete set sells for GBP 28,995 + VAT. Honestly I don't think there is any fair production cost basis for that, or for a three-jaws chuck to be priced GBP 1,395 + VAT.
  24. I've read about it. Shellac naturally contains 3 - 5% wax, that can be "dewaxed" to improve adherence for further painting. The flakes are more pale. I don't know which one I have for woodworking but the results are beautiful and very easy to obtain.
  25. You can also attach them to a posting, no problem with that.
