Someone has offered me this watch but I don't know the year so can't determine how much is to much to pay.
It's a front loading case, probably in the few years before Omega put DE VILLE underneath Seamaster so that makes it early 60's. If it's solid 14ct gold then it would sell for a minimum of $800 and more like over $1000. If it's gold filled then cut that in half. I'd like to see better shots of the dial to determine how bad those spots are - could be less valuable.
Those spots signify water infiltration into the case. Would need to see the movement to ascertain how significant this is. These watches are plentiful in number and readily available in nicer condition. Unless the price was great (especially if it was 14k gold) then I would search elsewhere.
