I was just telling the wife last night before seeing this thread it was a rep. Date is sunk more then the gen and the flat dial is beveled where the carbon dial you posted is not, although I've seen a few hublot that a somewhat sunk. Second hand comes like the rep (with red paint stopping before the h) on some models but never has on the SS/Rubber (although it has on the SS/SS, crazy). The boldness of the datefont is an easy give away head on.
The screws are not aligned on the gen.
Someone also just posted about the Istanbul they bought, which is the SS/Rose Gold bezel (the other rep) and is very rare and hard to find at this point. So he probably has a rep as well, although I think the first guy knew his was a rep.
