Good choice to pic the survivor Guru!
1. If I were you I'd get it on the rubber strap, quality is great. Concerning the hornback leather, you should get that one aftermarket IMO... The rubber strap is available separately though, just ask your dealer.
2. Like RKDK said, the gen has no AR. Usually I am not fond of AR on AP's but this one somewhat deserves it . Gen AP's do reflect a bit, but not as much as the rep due to the higher grade sapphire, I would opt for single AR on the inside. But that's all up to your own opinion, I like my reps as much gen-like as possible (not talking about frankens). The cyclopse of the Survivor has got AR, so I'd buy an AR'ed cyclopse from Uwe.

3. Hands and hourmarkers on the gen have lume, on the rep they are poor (pic below). Reluming would do the trick, I am always pro for a relume job! Let them glow!
4. For AR coating I would opt for Uwe, superluming as well .
Another thing, on the gen, the conversion links have red and green dots, I think this can be a nice mod, it's not necessary as nobody would notice it but you.
the dots:
Anyway, it's a great rep.
