The heart of Cartier Haute Horlogerie continues to beat, in the skeletonized versions that the brand issues for each of its models as well as in its innovative Grand Complication timepieces. Their inventiveness had made headlines at the time of their launch and this momentum is maintained by subtle variations on models such as the Rotonde de Cartier Astromystérieux. Its skeletonized movement is suspended from superimposed transparent sapphire disks, an illusion representing the fundamental concept of the brand’s Mysterious Hours. The caliber appears to be floating in space and spins like a tourbillon, completing one full rotation every hour. Its Roman numerals and the bridges forming its skeleton are coated with green Super-LumiNova. However, obtaining one of these five watches involves certain very special conditions, since the Astromystérieux is part of a set of three Cartier Haute Horlogerie timepieces – all made of platinum and all coated with luminescent material. Delivered in a very finely crafted marquetry presentation box, they are inseparable.
