Hello all, I have in my possession a Seiko case for an automatic movement. The back is not original to the case. the bezel is missing .  the I.D. and O.D. are 32.10 mm and 35.50 mm  for the groove the bezel would sit in. Could anyone suggest how I might find such a bezel?

if the case back is not original you're definitely going to have a problem. Usually when ordering components for cases for Seiko watches everything is based on the case back number. It could be a different case back as long as it's the right case back for that case then you could use the number. But if it's totally wrong case back here in trouble sort of? If you look at the dial usually on the bottom there is a dial number it's not exactly the same as the case number. But it helps to narrow down the range of what you're looking for.

They is probably I was Seiko is that they've made so many case components. They haven't old it's been discontinued desk of even a bigger problem.  I know their sites out there were people are modifying their Seiko watches if you can find one of those sites may be they of something generic.

That's what I was thinking. There is ALOT of interchange between Seiko cases, things are easy to swap around, too easy ! it does make for efficient manufacturing. The modders out there now seem to be mostly interested in dive watches , in that case bezels abound. This is a standard watch case, probably a Seiko 5 that got cannibalized along the way. I want to make something out of it ! I can find bezels of this type with Seiko part numbers from different vendors. There has to be documentation out there somewhere that can match these numbers to their dimensions, but WHERE ?

      Setting lever spring

      By mikepilk · Posted

      I would harden and temper (to a light blue). It's so easy to do and only takes a couple of minutes. A search on ebay UK for "spring steel strip cs" finds plenty available in small quantites and thicknesses from 0.1mm up.  But the question is ( @nickelsilver) which "CS" number is best for watch parts ?  Also, from one of the ads : "CARBON SPRING STEEL. SIZE IS METRIC 15.00mm X 0.10mm X 304 MM  CS100 FINISH BRIGHT . HARDENED AND TEMPERD TO 480-530VPN" I've no idea about 480-530VPN. Does that mean it needs annealing before working?       Have you seen this video, he shows how to determine where the indents go ?

      Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?
