Guys, why bother? I have the GMT-Master II 116710 BLNR Black/Blue Ceramic V9 904L (got it from Intime) and even wore it to my jeweler's (he is a certified Rolex dealer) birthday party and he didn't spot it is a fake (only after I told him and he looked very closely at it). I have a couple of gen watches from him, so we're good. Regular people will never realize it is a fake and even experts need to take a closer look to see it. So why bother and spend more money on a fake watch (even a Frankenwatch is still a fake one in a way or another).
I wore a fake Audemars Piguet ROO (LeBron version) to a watch collector's dinner invite and he saw the watch, was crazy about it. Took him a minute looking at it very closely to realize it is a fake. He told me that he admired the watch for over an hour after I sat down at the table but didn't realize it is a fake until he actually looked at it closer.
Unlike the jeweler, this guy wasn't cool at all with me wearing a fake, even after I told him that I own two gen APs (Safari and ROO Carbon). He wanted to know why I wear a fake watch and I told him I like the design and everything but I cannot afford to buy so many gen watches, so I get only a few and the others are...fake.
