I'm planing to finally buy Chanel J12 watch, but don't know which one? I know I like the diamond marker one, but not sure which size (33mm or 38mm) and which color(black w/ruby or white w/diamond). Currently I have Rolex Silver datejust(small ladies size), Cartier Tank F in combination color(small size), Cartier Pasha(about 35mm with black croc band), Chopard Happy diamond(small ladies size, with pink band), and Hermes clipper chrono orange face(38mm). So, I don't have black or white watch....so either can work I suppose....would love to know your opinions TIA!!
