I bout myself a SS Submariner, a Pepsi GMT II, my wife a Cartier Tank, my Dad a SS Sub (average qlty), and a buddy a black bezel Omega Seamaster Planet Ocean with nice blk rubber strap.
As I mentioned before, make sure the guys selling have a little work station set up near-by...these are the resident "pros" who know that you are serious and want to cut through the junk and B.S.
I got the Tank and Seamaster both for $75.00 U.S. combined but only after I bought the SS Sub $75, GMT II $75, and brought some co-workers with me. The SS Sub I bought on my first day was $25 U.S. very nice bezel, average bracelet, but I missed the tiny "18k" stamped on the back of the SS watch case (oops).
Lots of Omegas and PAMs of course....not so sure about Hublot.
Have fun....I sure did. I really liked KL and would go back again.
