I love my Vintage Series IWC Aquatimer. I think it's a very discreet watch and doesn't grab any attention to itself. I love that in a watch.
In the near feature I want to buy a TAG Heuer Monaco from one of the Gulf edition series, but I'm having hard time justifying $5k for a TAG. But then, I really like the shape, and there is the Gulf, and Steve McQueen...
I think Breitling is more for Audi owners. (runs away really fast)
