believe this is rep. look at the tabs on the back side of the end links - on the rep those little tabs are kind of trapezoid shaped while on the gen they are square. i will say though, the rep bracelet is *really* close to gen.
personally i think the clasp engravings look a bit thinner than gen and the stamps/engravings on the back side of the links dont look sharp enough (on the gen i think they look more 'etched'), though i could be wrong - it really is hard to tell unless you have them side by side in hand.
