Jinx to LHOOQ, I think you need to read the replies again HartDoc.
Doesn't look like anyone called it a rep, only told you what to look for to spot one. I'm staring at the U1 rep on my wrist now and indeed the dial markers are greenish tinted (very slightly), unlike yours which are stark white. Another tell, if you're truly anal, is that there's slightly more space between the date window and 3 o'clock lume marker on the gen than there is on the rep. The AR on mine is of gen caliber, and the rep rubber is really decent (they also did a great job on the steel's finish, matches a gen bracelet perfectly)... if it wasn't for the lume I'd call this a super rep!
