Watch Buyers in New York City

Was looking for a watch buyer in new york city and wanted to see if any of our readers here at Club At leticohuila had any advice on where to go. I went to the diamond district on 47th street and was rather amazed by the amount of traffic and agressiveness from the workers there I did not feel comfortable selling off my items to them and wanted to know outside of a pawn shop where people prefer to go in Manhattan? It is a rolex and a cartier timepiece that I am looking to get rid of. Any reviews on GGC & Diamonds?
