It's a fake. Omega never externally marked their gold case backs that way as far as I know. It's not solid gold as may be seen by the wear on the lugs.
It looks fake to my untrained eyes. But lets wait for the experts. Sent from my iPhone using Tapatalk
Fake I didn't even have to look at the second pic. Educate yourself. https://omegaforums.net/threads/don...omegas-post-them-here-not-for-questions.6235/
That's really unique. I have never seen solid 18K exhibit "brassing" around almost the entire circumference of the case back. Must be a rare prototype or something.
I think I even have that same crappy Spiedel bracelet tucked away some where, for, well, you know, truly special occasions. LOL.
