I inherited this vintage Omega recently, and was wondering whether anybody more knowledgable might be able to tell anything about it. The most similar watch I've seen is a Geneve. From the serial number it seems to be from about 1967. I brought it to my local Omega Boutique but their database didn't go far back enough to try to trace it at all. Recently had it serviced by a local shop because it went far too slow, and it seems to be fine now.
