Cartier Rotonde de Cartier Earth and Moon Platinum / Baguette

The Cartier Rotonde de Cartier Mysterious Double Tourbillon HPI00639 is a breathtaking example of Cartier’s mastery in both haute horlogerie and high jewelry craftsmanship. This exceptional timepiece features a 45mm 18k white gold case, fully set with brilliant-cut diamonds, including the bezel, lugs, and case sides, offering unparalleled luxury. The watch is powered by the Cartier Caliber 9454 MC, a manual-winding movement certified with the Geneva Seal, featuring an innovative double tourbillon mechanism. The tourbillon appears to float in midair thanks to Cartier’s “mysterious” complication, where the cage completes a full rotation in 60 seconds while the entire mechanism rotates once every five minutes. The skeletonized dial showcases Roman numerals integrated into the movement’s bridges, enhancing its architectural aesthetic. The sapphire cabochon-set crown further accentuates Cartier’s signature detailing. The watch is paired with a black alligator leather strap, secured with an 18k white gold deployant clasp, also set with diamonds. A sapphire crystal protects the dial, and the watch is water-resistant up to 30 meters. This Rotonde de Cartier model is a true collector’s masterpiece, combining horological innovation with the brilliance of haute joaillerie.
