okay here we have a womans watch, i've checked the numbers and i can't find a match on the omega database or google for that matter, it says it's a 620 series, the number inside is 5115002. i've not seen an omega quite like this and it's not exactly special to me, i'm wanting to sell this one but I don't even know how to describe the darn thing. it's a wind up, stamped 375 all over it, it's the skinniest watch i've ever seen, i'm thinking early 1970's, what do you think guys?
.375 means it's 9 ct solid gold. If you can read the number on the small raised outside portion of the movement (to the left of OMEGA) we can tell you what year it was made.
