In addition to the crown protectors, the lugs, the inclination, the angle drop from inside to outside, the very different crystal very clear in VSF and with the best cyclops among all the rep are also very different. I have VSF 116610ln and it is 90% Gen shape, VSF 126610 I never liked, it does not have a refined case. I'm still looking for a good Sub 41mm. So far the only one that convinces me is CF 126610, it is also different from gen but it looks refined, well brushed, and a very good overall finish. Every day I see thousands of photos of Sub 41 between rep and gen. It is the only way to get what one is really looking for. VRF has just released a Sub 41 as well, it's on puretime. We'll see how it is.
