Well, here is one of my fairly recent acquisitions. A vintage Stowa from the 1950s:
and the gold-plated movement:
I bought it off eBay for not much money at all, but spent about twice that for a complete cleaning & adjustment, as well as a movement revision (including new mainspring, adjustment, etc), as the movement was, as the seller put it, "overwound": in reality, a key part of the keyless works had broken and jammed the keyless works.
I'm still looking for that part, which is the spring that holds the crown into place, but haven't put much effort into it, as it's one of those things that will, at some point, turn up. The watchmaker didn't spend a lot of time trying to find it: he knows that I will find one ... one of these days.
Anyway, I'm home with a bum knee and finally got a chance to post this. The back of the watch indicates that it was given to someone - nameless - for 25 years service with the Essener Steinkohlen Bergwerke AG, a coal company in Essen, Germany. Had been rarely, if ever, worn, and I put it on a nice croc strap.
At some point I'll take the effort to find that part, the watchmaker will pop it in, and all will be good...
