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
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?
Okay, saw this and hadn't seen a Hawaiian watch before and couldn't pass it up for $20.00. Has anyone ever heard of this watch. Says swiss 17 jewel movement and Hong Kong dial. Sent from my SM-N975U using Tapatalk
I guess it is not going to be easy or cheap to get a basket for it. I keep looking. I can see some of the baskets in the USA now you mentioned, but I am not sure if the dimensions of the baskets are correct for national.
Hi OldHippy, I got mine about the same price + delivery yesterday without the basket unfortunately. I think there is a timer on it actually. That white knob behind the heated chamber on the right hand side.
