I dunno, man. The gen hands must be on the one on the right, they look shorter, but you'd have to be doing a side by side comparison with a VERY knowledgeable person (an AD or Panerai nut probably) to have anyone notice. If I were that nuts about it, I'd pony oup the big $ and get a gen. I don't think its worth it.
What are you doing with the crowns? Are you getting rid of the palp crown for the gen, or the other way around? I think the 2mm looks closer to the gen, even given the extra wide CG...
