I have an SS Roadster and am in love with it. I also have the Tank f (small) and a Cartier SS Must 21, however of my 3 Cartiers, the Roadster is #1 for me. BUT, since you already own 2 Cartiers and you have fallen for the Rolex Air King, why not go with something different than Cartier?? The Air king is definitely chic, cool and classy all wrapped into 1.
