greetings all-been a few months since I've visited hope all is well with everyone. question: do any charts exist telling of American screw thread sizes for vintage pocket watches? I seem to be having a tough time finding anything other than the fact that back then prior to the 1955 "thread summit" I'll call it, where the European and American powers-that-be agreed on a universal standard thread pitch across the board(UNM miniature), that European was metric and American was their standard inch pitches, with the exception of Elgin and Waltham, who made their own specific(adding to my frustrating confusion) threads. I have threaded holes I need to repair and/or chase, and I'd just like to have it handy if I need it. maybe I haven't looked deep enough?
I recently bought a lot of pocket watches on Ebay.
Between them I found an Alpina pocket watch with movement UH 1116. I saw on internet that usually is referred as Alpina 1116.
I got the following situation, while removing the wheels bridges, one of the ruby remained on the wheel.
Please take a look on the following pictures.
I also took some pictures with a microscope in order to explain better the situation.
Could you please suggest me what I should do?
Is what I got complete? Looking to another ruby it seems there is something missing (holding piece?)
Is the movement common? Do You believe I can find the bridge somewhere?
BTW I have also found a broken spring
Many thanks in advance for your suggestions
A friend of my father gave me this old pocketwatch to see if I could repare it.
As you see in the picture, the balance wheel is extremely bent. I tried to bend it back, but i cant make it good enough.
Does anyone know where I can find a balancewheel for this Revue 30 movement? I have tried to search around online, however, I cant find any.
Is there a generic balance that would fit in here?
I have an old Waltham pocket watch movement which is missing the impulse pin (roller jewel). I have a limited number of actual jewels and since this is just a practice movement I thought I'd try to make one out of brass. I've seen this several times in old pieces--usually a very sloppy job. So I got some brass stock of the same diameter as the "D" in the roller table, filed it and burnished it to a high gloss. Then I took a small, very fine diamond file and filed it half flat to form the "D" I then polished the face using progressively finer sandpaper on a steel block. This works fine--so far! Problem is separation of the piece from the stock. Again I used a small cutting file to do this but it doesn't leave the end very pretty. So what I've done so far is to fit the good end into the roller table. I then plan to shellac it in place and see if I can very carefully adjust the length and clean up the end. Has anyone done this before? Any suggestions as to how best to do it?

Yes, I know...very basic question, and probably been asked here before. I'm an IKEA veteran and I can somewhat tell, when assembling IKEA furniture, if I've seen this screw before or not. However, while assembling watches, this get's somewhat confusing, and I have no clue why this never seems to be an issue, or a special topic in the Watch Repair Channel, or other watch assembling videos I've watched...or maybe it has and I've missed the point? So my question is, how do you do it? Thanks for reading, Magnus
Thank you for your introduction and welcome to this friendly forum. Ask away on here we all like to help, photos can help a lot.
Pleased to forum-meet you all. I'm here because I've enjoyed the Watch Repair Channel very much. However there are a few things I'm still very uncertain about, probably very basic stuff, so that's why I'm here, to read your posts and ask some questions. Cheers! Magnus
