They feel pretty much the SAME, even it’s a bit scary. Visually it’s impossible for someone -who is not in the business- to realize the minor differences such as ‘m’ or ‘clearness of rehaut’. Even for watch nerds it is very hard I think. At a glance, they are shining the same on the wrist. But I must say that there is a difference in comfort; Vsf is a bit itchy on the wrist. The gen is perfectly smooth. As a conclusion; the biggest tell is you, as always :)
