I'm afraid it's a fake or more correctly, a counterfeit, not a real Omega.
How can you tell?
Because I've studied vintage Omegas for years and have seen thousands of genuine ones and thousands of fakes.

Stating it is 18kt gold are almost never on the outside of cases. Dead giveaway;
Thank you! I wasn't questioning your expertise, just looking for specifics I could give to highlight that it isn't real. Thank you for the link! I'll check it out!
Thank you all for the feedback! I really appreciate it. The family member in question doesn't believe me so is going to go and have the "diamonds" checked tomorrow. After reading the info provided I'm confidant what the result will be. Disappointing, but better to know!
I just ran across this forum while trying to research the authenticity of a watch. I have a ladies watch that has been with my wife prior to our marriage over 25 years ago. It appears to have been made after 1959. I am asking if any of you can give any advice on its authenticity as my wife has asked me to sell it for her. I do not know if it is authentic, nor the sale value. There are no markings on the back of case, and only OMEGA on the inside. Thank you for any advise.
