No doubt that these guys as you labeled the BTD's are in collusion. There is no way that, if these watches had been modded like some of the folks on the VRF are alluding to that it wouldn't have come out. But you have two things working here, the dealers who are "upscaling' their watches, and the guys who are buying. If a "collector" buys a pristine 6538 and pays a big premium for it, but months later gets a little suspicious and is pretty sure that his watch has been enhanced, he isn't going to say a word. First off, if he screams foul, most of the others on the forum aren't going to believe him, and second, as soon as the word gets out that his 45K watch isn't as it seems, the price is going to plummet. So for his own good, he's not going to say anything. Who knows how many other folks are insiders in a deal like this. Everyone on the VRF wants the most pristine, perfect examples for their collection.it is not in their best interest to make a big deal about this, because if the heat gets too bad, the dealers who are supplying these 40+ year old factory fresh watches will simply disappear, or sell regular run of the mill watches like everyone else.
What really aggravates me is what these "modders" are doing is exactly what we do here on this forum, making a good watch better. the big difference we are all up front and open about what we do, those guys are all shadow players, and everything they are doing is for financial gain, at the expense of their fellow Rolex collectors. It's absolutely heresy to sell a watch with an aftermarket insert, bracelet, crown or a refinished dial, but it's perfectly all right to laser weld a case to build it back up to original specs, or "touch up" the lume on a dial, as long as you are the right person, and everyone thinks that you are the worlds greatest procurer of Vintage Rolex watches. You want papers with your watch, no problem, i can make a punched paper, sales receipt, find a period box, booklets, etc, get you the whole set for lets say a 4k premium over a comperable watch W/O papers. Pretty good business!!
