Hey everyone, I'm the super new guy around here! I've been collecting watches for a few years now and just got my first Omega and I really like it. I picked it up used with box, papers, and card and took it to my local Omega dealer to get sized. And this is where my dilemma starts. The salesman at the one and only Omega dealer where I live looks at it and says that he has never seen a GMT with a sliding hidden clasp that I have on this watch, and is concerned about it's authenticity. I asked if he could contact Omega to verify my SN and it's authenticity but he said that is something I would need to do. Anyway, I just wanted to post up some pictures of my first Omega to get some thoughts from the experts. I'm also going to contact Omega customer support and inquire about my watch. Does anyone else have this timepiece? If so, what are your thoughts on it. Thanks!
