Rotonde de Cartier Astrotourbillon watchManual, pink gold
In the Rotonde de Cartier Astrotourbillon watch, Cartier introduces a movement that has been designed, manufactured and assembled by our very own master watchmakers. This unique, creative movement has been in development in the Cartier Manufacture for five years. The caliber 9451 MC is a revolutionary tourbillon because it incorporates an elongated carriage that enables the balance to complete one circuit of the dial every minute, like a celestial body. The balance bridge in the form of an arrow thus replaces the central seconds hand. Cartier has chosen an elegant modern design to showcase this unique movement: the Rotonde de Cartier case with a diameter of 47 mm. All these characteristics combine to make this watch an exceptional example of Fine Watchmaking.
