Cartier Rotonde de Cartier Mysterious Hour Pink Gold

The Cartier Rotonde de Cartier Astrotourbillon W1556223 is a groundbreaking timepiece that redefines the tourbillon complication. Featuring a 47mm 18k white gold case with a thickness of 15.5mm, this watch is powered by the Cartier Caliber 9451 MC, a hand-wound movement designed specifically for the Astrotourbillon. Unlike a traditional tourbillon, which rotates within its cage, the Astrotourbillon’s balance wheel completes a full orbit around the dial in 60 seconds, creating a captivating visual effect. The skeletonized dial integrates the Roman numerals into the movement’s bridges, adding a striking architectural aesthetic. Blued steel sword-shaped hands provide contrast against the open-worked design, while the fluted crown, adorned with a blue sapphire cabochon, enhances Cartier’s signature elegance. The watch is paired with a black alligator leather strap, secured by an 18k white gold deployant clasp. A sapphire crystal protects the dial, and the timepiece is water-resistant up to 30 meters. This Astrotourbillon model is a true testament to Cartier’s innovative spirit and mastery in haute horlogerie.
