The Rotonde de Cartier Grande Complication timepiece may be the most complex wristwatch Cartier has developed to date. Cartier aptly describes the watch as “ultra-thin.” The caliber 9406 MC movement is 5.94 mm thick and holds 578 components. The platinum case is 12.6 mm thick. The skeletonized movement includes a minute, repeater, flying tourbillion and a perpetual calendar. The mechanisms are supported by two large horns that also frame the tourbillion. The watch was created under the supervision of Carole Forestier-Kasapi, Cartier’s director of movement creation and is limited to 50 numbered pieces.
