I agree with this. But saying that 70% of 5-digit references have lighter hands doesn't really help you determine whether a particular example has original hands. I'm certain that when
@mr.kaplan inspects a Rolex in-person with a loupe, he learns a great deal from the specific color and texture and UV-response of hands and dial.
I truly believe that the OP will never make progress without handling watches in-person. He claims that art experts use books to develop their expertise, but personally I doubt it. If he doesn't want to buy a watch, there are various other ways to accomplish this, including networking with other enthusiasts in-person, finding a mentor, visiting dealers and retail store-fronts, etc. He is falsely characterizing suggestions/advice from me,
@Davidt, and others as attacks, playing the victim card. What I am seeing is a common theme on OF, where members eventually become frustrated by repeated requests for spoon-feeding from a member who is unwilling to make a real effort to learn. I have been following the OP's repeated threads for almost a year now, where he continues to ask the same vague and naive questions about various Rolex references. He claims to have experience in the art auction world, so it strains credulity to believe that these questions are sincere. The same questions have been asked and answered dozens of times on this forum and others, and the vintage Rolex models he is referencing have dedicated reference websites that he can study if he is interested. Two minutes of googling will identify these sites.
