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?
Hi, so I recently got a seiko 5 snk809 and it was working fine, I then decided to regulate it as it was losing about 1 minute a day. After I regulated it it was working fine then stopped so I shook it to wind it up and then it started working. After 5 minutes it stopped again so I wound it up and it would work but then stop after a couple of minutes. I checked to see if the watch was being winded and it was, so the watch had power but just wouldn't move, I dont know why this is, the watch has power but will only run for a minute or two when I shake it, this hasn't happened before to this watch, so if anyone could help that would be great.
I am after a clasp for an old digital junghans watch, I wasn't sure if this forum permits these requests?
I did check the forum rules and it makes no mention of it only about selling.
Can one of the more seasoned members help before I post the request?
I own an old Elgin pocket watch and am trying to remove the screws to the main barrel and the stem but they are extremely tight to the point that I'm finding it impossible to remove them - even with a lot of force and pressure.
I do not want to damage my watch as it is an antique but at the same time do not want to send it to a professional if I can get it undone myself.
I've tried different sized screwdrivers to no avail, and understanding that it is a no-no, I've even used a cotton swab to apply WD-40 directly to the screw. I do not know if the screw has rusted or not - the watch itself is immaculate so I see no reason for the screws alone to rust.
Does anybody have experience removing stuck screws from their watches or pocket watches? These things are absolutely tiny!
I am considering selling leather watch straps, but I have a question before I blindly go ahead and produce a bunch of them.
I am wondering if anybody who has worked in the industry for a while can tell me what the most common sizes are of strap pins or lug widths?
I would really appreciate it. Thanks in advance.
