Hi guys, After having a little break from chasing after vintage Omega's and trying to find a nice vintage seamaster a friend of mine, also a vintage watch enthousiast, offered me a chance to buy a Omega seamaster cal 562 ref 14760. It seems to be legit. The only thing i can't really find on similair watches are the little green dots on the bezels. Is anybody here familiar with these dots on the bezels? Many thanks in advance Best, Cris
