The Key is in the Crown

As Cartier aficionados know, the crown of Cartier watches is always a distinguishing feature, from the protruding blue sapphire cabochon on the Tank watch to the round protection cover on the Ballon Bleu. The Cartier Clé watch introduces a novelty with its rectangular-shaped crown, which resembles the antique keys used to wind pocket watches and clocks. Cartier's hallmark blue sapphire has not been excluded and has been fitted inside the rounded contours of the rectangular case. To adjust the time, the key can be pulled out and turned to the accompaniment of a reassuring click.

Each of the models in this new collection of Cartier watches houses a cutting-edge movement developed and assembled by Cartier's watch manufactory in Switzerland. Calibre 1847 MC is a new automatic movement with a dual-direction winding system ensuring a steady power supply of 42 hours, which keeps the hours, minutes, central seconds and date functions in perfect time.
