Hello! I'm new to the forum and purchased a vintage Seamaster 120M at an estate sale. Don't know too much about the Omega brand and am new to collecting vintage watches but I think I did okay with it. It had been inspected by a certified jeweler that confirmed it was authentic. The S/N is 25112000. Just curious about the details on the year etc and am wondering if anyone has seen a band like this? Is it period? The watch is currently not working but I am going to take it to get repaired this week. Would love your thoughts on it!
