I just bought the Cartier Ballon Bleu two tone 36mm automatic and now I am second guessing myself and wondering if I should get the smaller size 33mm instead... Or even the stainless Ladies Tank Anglaise... Eeek! I am tall and can carry off the large 36mm size but not sure if it is too "sporty". This is my first nice watch... Any suggestions?? I am 36 and want the watch to last...
