Hi guys, I picked up a bag of mixed watches over the weekend! I’m curious if any of these is collectible at all and would be worth having a watchmaker restore. My question is on the Waltham. I have no idea how old it is because all of the serial number guides I find aren’t doing me any good. The movement doesn’t appear to have a serial number similar to the guides I’m seeing. Does anyone have an idea? From left to right I have a 1971 Citizen, 1966 Bulova, the Waltham in question, Unknown age Lucerne, 1950 self winding Bulova, 1980 Timex, 1983 quartz Bulova. The three above I’ll make a different post about as I don’t know anything about them. They’re a Richard and a Benrus, both self winding, and a French watch I can’t quite make out the name on. The first four watches on the left seem to run well. The rest won’t run.
