If were talking a stainless & 18k diamond dial Rolex vs. a white gold Cartier with diamond bezel, isnt there a HUGE price difference? Is there a stainless and 18K white gold version, or is it just in two tone 18k and stainless? I love the Ballon in all white but I don't care for it in 2 tone, it changes the whoel look of it for some reason, not as sleek... For a solid gold watch with diamond bezel, the Cartier seems a bit dressier but with diamond dial in 18k & stainless, I would go with Rolex.
