Well as far as compared to my gen PO the logo on the crown is a flaw I can see. The Omega logo on my crown is much more rounded and much crispier. The rubber strap on that watch seems of a very low quality (you can clearly see the excess rubber on the sides of the strap from the mould). Another thing is the tang buckle. I'm not sure if its just mine but on all of the OP I've seen (gens) the tang buckle is brushed not polished and the Omega logo is DEEPLY engraved on it, not laser etched. Also there are no serials on the back near the lugs. The dial looks pretty good to me. No major flaws I can notice. I hope this helped. I'm not much of a Omega guy so you might wanna get an opinion of some our Omega guys (if any around here)
