Hi All! So I'm in the market for a two tone Cartier watch. I've narrowed it down to: Roadster, Ballon Bleu and Santos. Whichever one I get, I'll buy it with the small face. I currently own a stainless steel small Tank Francaise which I have no plans to part with I do have a two tone Michele Diamond Urban Mini (and a few other Michele diamond watches) but I've wanted a two tone Cartier for so long and I can finally afford it. What do you think? Ballon Bleu, Roadster, or Santos? TIA!
