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 WE902075 watch we have here is for women, and it comes in a 36 mm case size. The stainless steel Cartier watch has a silver guilloché dial set with diamond hour markers, sword shaped hands, and an inner minute track. The classic round case fastens to the wrist with a comfortable link bracelet.
