Does anyone know what sizes English/American pocket watch use and type as in BA or mm and if possible drill size, there are many model engineering supply's in the U.K. But it's knowing what to get.

many thanks

I just checked my Elgin catalog and there are 8 pages of screws. Just. Screws. I've attached a photo of just the first page, if you're interested I can post a link to the whole pdf file.

Elgin and Watham made their own thread sizes for their pocket watches so you cant buy new taps and dies to fit their old watches. You need to find an old set off ebay when they turn up that are hotly contested.

Guessing the newer wristwatches made by the Swiss branded as Waltham and Elgin used metric threads

    • Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!
    • Happy to have helped, great way to start the day with a win! 🥳
    • Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. 
    • I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂
    • Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
