Nazi era Hanhart Chronograph!!

[nzwatchdoctor]

I got one of these from a good customer / friend for a replacement stem.

It's the real deal with the eagle and Swastika on the back etc. 

He got it with a broken stem. I couldn't id the movement so sent it to a friend who's a better watchmaker than me (not hard to do...) and he's managed to find a stem and modify it to fit. 

The problem now - part of the stem is sticking out from the crown but it won't unwind - even in his lathe. 
I'll give it a soak in a solution and try again but we're not hopeful. 

If I can't get it off getting another crown will be difficult (screw down) and it won't have the patina that the case etc has - not worn - just a nicely aged colour.

Or here apart from I've not got it back yet and I have to post photos to a third party - Quram(?) which is a bit annoying to do.

Boil or heat the crown.

If it's been glued, boiling should in most cases brake the bond, but wont damage the gasket.

If boiling doesn't help, try heating the crown with a clean flame. I recommend removing the gasket first, so that it doesn't melt and then put a new one in later.

Thanks for these suggestions. I'll try them.
