    replacement crown for Junghans calibre 87?

    I just picked this up for a few bucks, to hold me over until I can afford my Nomos , but it needs a stem & crown

    I found a stem on the 'bay, but I need to find a crown, as well. I was looking on ST supply. I'm assuming that, to know which "tap" to get, I will measure the diameter of the stem where it goes into the crown?

    Also, I've found "post:flush" and "post:medium." Would it be possible to determine this from looking at this picture of the case?


    Thanks!

    That would be a flush post waterproof crown. For some reason watch crown tap sized follow no logic, but yes, measure your thread on the stem. Tap sizes go like this: T6=1.20mm, T9=1.00mm, T10=.90mm, T11=.80mm, T12=.70mm. You'll need to measure the case tube diameter as well.

    Thanks so much! Would have never known any of that and played a not-so-fun game of trial & error...


    Would you happen to know the hole size for the seconds hand? I'm not sure if it is original, or perhaps if part broke off, as it's shorter than the minute hand. I'd have to bend a replacement if I get one, so I'm contemplating whether I want to attempt that...
