You can also buy a Cartier Tank FranÃ§aise at Costco.
I think that supports my argument about buying a timepiece from a watch manufacturer rather than a design house... oh snap. (I love the Tank Francaise FWIW) I forgot to mention that the movement on the Pilot Spitfire, Mark XV, and Portofino are all the same for IWC. That's not necessarily a bad thing, just another tidbit to point out. Doesn't watch shopping suck?
