1960s Omegas, besides poping the back off, any idea how to check which one it is ?
It seems to keep time for ~24 hours then kinda dies. I believe it's a hand wound watch, rather than a pure automatic but not sure.
Definitely needs serviced, but the nearest place for it is actually Omegas flagship store in Geneva, I'm sure that won't be cheap.
Sorry for the shit photo, was sent from my father
