Cartier Rotonde de Cartier Earth and Moon Platinum

The Cartier Rotonde de Cartier Astrotourbillon W1556222 is an avant-garde interpretation of the traditional tourbillon, redefining movement in horology. Encased in 47mm of 18k pink gold, this watch houses the Cartier Caliber 9451 MC, a manually wound movement featuring the Astrotourbillon, where the balance wheel completes a full orbit around the dial in 60 seconds. This celestial-inspired complication creates a dynamic visual effect, setting it apart from conventional tourbillons. The skeletonized dial integrates Roman numerals into the movement’s bridges, offering an architectural and modern aesthetic. Blued steel sword-shaped hands provide striking contrast against the open-worked design. The sapphire cabochon-set crown adds a signature Cartier touch. The watch is paired with a brown alligator leather strap, secured by an 18k pink gold deployant clasp. A sapphire crystal protects the dial, and the watch is water-resistant up to 30 meters. This Rotonde model is a testament to Cartier’s commitment to innovation, making it a prized addition to any haute horlogerie collection.
