An icon in the making, the ‪Clé de Cartier timepiece features the newest manufacture movement: the 1847 MC, developed in-house by Cartier.

Combining cutting-edge technology and in-depth expertise, the new movement was developed, produced and assembled by the craftsmen of the Cartier Manufacture in Switzerland. Its name — 1847 MC — pays homage to the year the Maison was founded.

"Clé" means “key” in French and the crown’s resemblance to one is unmistakable. The act of resetting the time and date introduces a new gesture to the world of watchmaking, one that recalls the traditional turning of a key to wind up a clock.

Elongated and pure, it is adorned with a sapphire that is not set in a classical manner. Instead, it is ingeniously inserted to remain flush with the metal surrounding it.
