First created in 2007, the Cartier Ballon Bleu watch is a song of details and harmony. The now iconic watch gets its identity from the guarded blue bubble of the winding crown on the side. The Ballon Bleu 3682 watch we have here is for women, and it comes in a 33 mm case size. The 18k rose gold Cartier watch has a silver guilloché dial set with Roman numeral hour markers, sword shaped hands, and an inner minute track. The diamond embellished case fastens to the wrist with a comfortable alligator bracelet.
