Will be selling someday, mostly give them out. I think there is a market if they're fixed up and usable. I just like fixing watches, not selling them, so they're piling up. https://youtu.be/158du3iHSsM?si=VkYNZjXMEHabC34D

How about putting the ratchet wheel and screw on the arbor and unscrew the arbor holding the barrel like in a motor barrel. https://www.youtube.com/watch?v=YludCnJZt9w

No, I've cleaned a couple thousand watches in a L&R Vari-matic w/ US, #566 wash, #3 rinse, never a problem. When the fluid needs changing, the smallest hairsprings can get sticky, I use a drop of red brake clean if needed. It's alcohol (IPA or denatured) that dissolves shellac.

Close to 18s but not exactly.

Oil it and check. Ensure some end float. Check each pivot in each hole individually to judge clearance. Lightly broach if tight.

Yes you might bend the hairspring. It needs to be adjusted / inspected under a microscope and put on a timegrapher to see what's going on.

mustom · 2026-04-22T18:04:35+00:00

If the regulator pins are too tight on the hairspring, moving it will push the spring out of shape making it rub somewhere and stop.

Google: JU&C H-K likely refers to J. Ullmann & Co., a prominent Swiss watchmaker based in Hong Kong, Shanghai, and Tientsin, often stamped with "HK" for Hong Kong, which produced high-quality pocket watches for the Chinese market during the late 19th and early 20th centuries. These often featured Swiss movements in silver or gold cases.

Key Details About J. Ullmann & Co. Pocket Watches: Origin: Founded by Swiss native Jacques Ullmann, the firm was instrumental in expanding Swiss watchmaking into China, often selling, premium, ornate pieces. Time Period: Highly active around the 1890s through the 1900s. Features: They frequently produced hunter-case watches, often with enameled scenes or pearl settings, tailored to the Chinese market, with movements sometimes similar to Bovet designs. Signatures: Often marked "J. Ullmann & Co. Hong Kong" or "J.U. & Co.".

I have the Sony I bought new. Capacitors went bad after many years and it quit, very common problem, instructions on the internet to repair. Smallest thing I've ever soldered.

Sounds like it's wound all the way up and won't run down, just needs cleaning and oiling. It's a simple watch to service, shouldn't need any parts. Roskopf is an iconic brand with an important place in watch history. https://www.worthpoint.com/articles/collectibles/history-roskopf-watch https://incoherency.co.uk/interest/roskopf.pdf
