i was in my local jewellers today as he had sized a rubber strap on a vintage omega for me. I have known him for years and bought several watches off him and we both love watches and talking about them. He said have a look at this stop watch as it came in today and I want ex amount for it. On a whim I bought it. It’s maybe a tad big to wear but looked in good condition. Does anybody know if it’s right, how old and what it was used for.
