Hello omega community. My dad loves omega watches and has recently acquired a good example of one. It's is 18 ct gold, seamaster, antimagnetic manual wind up. The engraving on the back has worn and. Does not show in pics but reads 18k 0.750 seamaster then "ge" but could be "gents" just worn out. My own research suggests circa 1950 but I can't find a single example online that is identical to this. We would very much like to know the date and value of this watch.
