I've been wrong many times before, so I thought I'd check with folks here with more experience, but this movement has significant damage, right? I'd also guess that the chances of finding a replacement part are pretty low, unless the cal 320/321 updated version is compatible.
I’m by no means experienced, quite the opposite.
However, I thought I will try to understand what the issue is, but I have hard time locating the problem. Is it about part 320.1724?
I wish Santa would give me something like this for Christmas.
There is nothing I like better, than a loose collection of watch parts to assemble. Too bad there really is not a Santa to give me one tomorrow. The Santa's I know tend to deal with more practical things and have trouble with abstractions like My wanting a complete Lemania CH27-12 or a 351 with case with all the parts ready to clean and assemble. I put pillar wheel Lemania on my Christmas list. Santa was most confused.
It is not like I do not have three Lemania watches/movements. None though are pillar wheel.
By the way, that’s a really early serial number, probably part of their first run, for an Omega 320, which came before the first 321s. Dates to late 1942, early 1943.
