Hands down (extra hand in this case). I'd get the new GMT. The subs are way too common. I wouldn't even get one in rep. The new GMT is one of the top Rolex models right now IMHO. I wish they made a proper rep. And that's another reason to get the new GMT. Too many tells on the rep. Ceramic insert and CHS being the main issue for me.
Angus is working on the black bay if you like a bit more bling, like I do. So the rep is a good choice there because not many recognize the Tudor brand anyway. Even some who do look at it as sub par(no pun intended again). I know people who do. Whatever.
GMT hands down.
