Mystery clocks, with hands that appear to float on the dial, have been part of the Cartier heritage for more than a century. Today, the mystery that was developed by the expertise of Cartier's workshops is extended into two new watches with Fine Watchmaking movements: Rotonde de Cartier Double Tourbillon Mystérieux, Calibre 9454 MC and Rotonde de Cartier Mystérieuse, Calibre 9981 MC.
