There is still a lot of discussion about Rolex / Pateks availability and price and this is probably one of the best videos on the subject.
It is nearly 20 minutes long and the first 10 minutes are tutorial and the final 10 are summation and predication. For what it is worth, I think the man has got it right.

I hope you enjoy it, I certainly did.
