As a new member of the group I thought I would ask for information about my old fathers watch. Still works great, with slight greyish tinge starting around the 3 Oclock marker . Is it a 1950's Watch ?
May be cal 2646 late 1950s. All info inside Caseback and SN on movement
Can you show more photos Caseback and sides
Dark part of dial on crown side may indicate prior water ingress. Hard to tell with shadow on that one photo more pics helpful.
