Tolerances of Manufacturer are very very strong. Chinese Workers have more space for flwas in their Production.
I upgrade every watch what stay in my Collection with Gen Crystals, why ? Because the difference once you saw it in direct comparison ( not on Photos) in real life in your hand, you´ll understand that its worth 350 $.
Saw good VSF Crystals and Bad ones that´s the Game in Rep buisness, but definitely not so perfect as Gen Rolex Crystals and thats in most Cases more flaw than the dial or Hands.
