The cartier rotonde de cartier astromystérieux
Given the level of recognition that Carole Forestier-Kasapi – Cartier’s head of movement creation – has achieved with her flying tourbillons and watches that mimic the brand’s famous see-through mystery clocks, it was only a matter of time before the master watchmaker combined the two concepts in a single timepiece.
The Cartier Rotonde de Cartier Astromystérieux uses four separate transparent sapphire discs and an elaborate ball-bearing carriage system not just to rotate the movement once an hour without any visible support, but also to wind the barrel and set the time. The watch, which has a palladium case, is limited to 100 examples worldwide.
