Thanks for the welcome guys
Hey Eugene - your Svet is very quaint! It looks like it is <30mm wide?
I guess you probably don't want to clean it yourself using lighter fluid to wipe the face in case the numerals come off.
I'll send you a PM of the repair guy I use. He's outside London and so is a bit cheaper ...
Of the sentimental watches I have to repair, I'm not doing very well with them. One was a hand-wind and cost £50 about 10 years ago. The automatic movement ones are harder to repair due to obsolete parts.
