Thanks Hartmut! My apologies for the valuation question.Welcome to Watchuseek. I'm sorry but we don't give valuations here - there is a sticky plus something in the Rules & Guidelines as to why not. The watch looks like it's from the 1960s. Vulcain were a noted brand who made the first modern wrist alarm (the "Cricket" - now once again in production). This one will, however, probably either have a totally generic movement or something by Revue Thommen who they were cooperating with inside the M.S.R. group.
