I reply only because I too as my first reps wanted a brietling and a rolex. Dont remember the brietling's model, of course I wanted a sub.
Anyways, I dont believe there are rep dealers (i.e. TDs) in NYC (or even other places) where you can knock their door and buy some high quality contraband. Of course, you could find non TDs in Canal St. but their wares might be suspect.
If you want to buy from TDs, they are located mainly in China. There is a list can be found with a bit of searching. Be prepared to spend a month from order to delivery.
