What model is this and what year? I would like to check if this is Authentic please? Does this have a reference or serial number? Is this Solid Gold or Gold plated? How much would it be worth? Is this Automatic or Manual? What Kinda movement? How old would this piece roughly be? Would (467 to 507 USD) or (303 to 327 Pounds) be worth it?
The stamping on the underside of the lug is .375 which is the decimal equivalent of 9 karat gold. Likely an English made case. The movement is an Omega calibre 267. I am unable to read the serial number, but I would guess the watch to be possibly from the mid to late 1940s. It is a manual winder. The reference would be stamped inside the case back. Looks like a nicely preserved original watch, and I would suggest well priced in the range you quoted.
17 million serial number = 1959-60. Omega 30mm movement, one of the best Omega ever made. A nice old watch. Price is decent. gatorcpa
