Well, just to summarize...
All you need is to get a 'Chistopolski' movement with good parts you need and replace just the parts, leaving the original movement in your watch. Also, a 2ChZ movement from 1940-41 should do as well - it's exactly the same. This should not be an extremely difficult task, sadly - I don't have one at hand

Good luck with the search

Dear friends, unfortunatelly I don't have positive news about my watch.
The watch which I bought in Ukraine is out of order, it works a bit then it stops.
I thought my watchmaker could repair it.
My idea was to make to make one watch out of two watches.
After meny trials my watchmayker (is an excellent old craftman) told me that balance staff is now not the biggest problem, but the main problem is the whells are worned a out.
Evrithing was tried to make one functional watch but there was no result.
The watch works properly a few hours then it stops.
I'm wery sorry but my watchmaker told me that he would contine again, but I'm not optimistic,(after two months waiting), at the moment I dont have I new photo, but if I get I positive feedback I will share it with you:D
