One thing for sure the date is more visible on black....I think the best looking is Black but the grey is so unique it might be harder to recognize as Replica, the blue to me is irrelevant since its a copy of the 2531.80 even in gen and considering the prices for good 2531.80s there is no excuse not to own one.
Absolutely agree on the date legibility on the gray dial-I can’t read it in anything but good light.
I find the Omega lettering and logo to be very faint too, all reasons that made me choose the gen in black and VSF in gray.
By the way, the poor legibility is not a VSF thing, I found exactly the same holding a gen version of each while deciding which to buy.
