Hi. I was not a fan of J12. But I tried on the black 33mm with ruby markers, and I totally fell in love with it (can't do 38mm as I have a very tiny wrist). The only thing I am concerned is whether I will be tired of it soon. I was thinking about Cartier Ballon Bleu, but I was not so compelled about it as the J12. Should I take the plunge? Those of you who own J12, can you see yourself wearing it for another 10 years?
