I need a stem for my Cal 59 since mine's been snipped off short (GRRR! A POX on watch butcherers.). Roland Ranft's archive says it's a W1110 stem. Anyone have a modern part number for this stem? If not available, then what's the tap thread? I can use an extender if that's all there is for a solution.

I also need to find a standard seconds hand for it. No one has the pin size listed anywhere. Length is easy, but I have no idea what size the pinion is. (I'm NOT going to stick my dial caliper on it and risk breaking it off! Not with MY hand tremors.) If I can get the pinion size, I can fit a smaller pocket watch seconds hand if necessary.

If I can get these parts, and give it a cleaning, the 2 year rebuild will be finished and I can finally wear it. (There's a whole story about me fitting a small dial movement into a modern waterproof case in these past 2 years. Quite a few case mods to do it but it's do-able.)

So... Help?

That's the Flume part number, normally you would just order a winding stem for a FHF 30 or common Swiss part number 401, thread probably is a 90 or 0.90mm, Ronda part number 131 and a thread of 90 according to the book
