Cartier, master of shaped watches, presents the Clé de Cartier. The design is a testament to accuracy, balance and proportion; with soft curves, clean lines and a rounded profile Clé owes its name to its crown. Considerable mastery was required to create fluid lines and a harmonious ensemble. The 35 mm and 40 mm Clé de Cartier models house the calibre 1847 MC, the new Cartier Manufacture Movement.
