Rolex monitor grey market?

[Sailaway]

There have been some interesting threads here recently about 'flipping' and subsequent consequences (for AD and staff). I'm just curious - do you think Rolex SA or AD's monitor sales threads, or use other means to 'follow' recently sold watches? In the absence of a warranty claim its hard to imagine how they could.... I'd be interested in peoples views......

I've never bought used or from a grey before, but my guess is people buy from a grey and attempt to check the authenticity of the watch on their own. Naturally, this could involve contacting someone related to Rolex "officially" like a local AD or even corporate by phone (?). I don't know what AD policies are on this, e.g., are they even allowed to opine, but perhaps they've been instructed to notify the mothership when someone comes in with a new watch asking to confirm authenticity.

I'm sure other members with far more experience have thoughts of their own. I'm also guessing there are people who spend at least some time in an official capacity monitoring sale listings for new/like-new inventory in the grey market.

What if you pick up a Rolex on the pre-owned market that was originally sold as grey several years earlier. Once it is out of the warranty period and you have to pay for servicing anyway, does Rolex care?
