578 components, 5 years of development, 15 weeks of production at the Manufacture, 10 weeks of decorating and finishing and 5 weeks of assembly were necessary to develop the Rotonde de Cartier Grande Complication. The self-winding mechanical movement is only 5.49mm thick and it combines three of the most prestigious Fine Watchmaking complications: a perpetual calendar, a minute repeater and a flying tourbillon. Equipped with the self-winding calibre 9406 MC, the timepiece is “Poinçon de Genève”-certified.

Thanks to its openwork dial in 18-carat gold and its skeletonised movement, the Rotonde de Cartier Grande Complication plays with transparency in a myriad of different ways. The skeletonisation of the calibre 9406 MC allows the minute repeater, perpetual calendar and flying tourbillon to be fully apparent.

The calibre 9406 MC gets its energy from a platinum micro-rotor with “guilloché” and “Côtes de Genève” finishing. The innovative construction of this two-level micro-rotor enables a reduction in winding speed while limiting energy loss.
