The Ballon Bleu watch was created from a new vision of roundness which, for the Cartier designers, involved giving volume to the circle. Doubly convex, its shape strikes the perfect balance between line and volume. To avoid any breaking of the line, the sapphire crystal winding crown is perfectly integrated into the case, with the crown cap under a metal hoop at three o’clock protecting the blue bubble.

The Ballon Bleu de Cartier watch was created in 2007. Worn by both men and women alike, its personality and comfort is best appreciated when worn. This piece rapidly became a resounding success and a Cartier icon.
