Cartier Rotonde de Cartier Calendar Aperture and Power Reserve Stainless Steel / Silver

The Cartier Rotonde de Cartier Minute Repeater Mysterious Double Tourbillon W1556369 is an extraordinary timepiece that showcases both Cartier’s horological ingenuity and aesthetic mastery. The 45mm 18k white gold case houses the hand-wound Cartier Caliber 9407 MC, which features two of the most prestigious complications: a minute repeater and a mysterious double tourbillon. The minute repeater utilizes cathedral gongs for an exceptionally deep and rich chime, while the mysterious double tourbillon at 10 o’clock appears to float within the dial, with the tourbillon carriage making a full rotation in 60 seconds and the entire mechanism completing an orbit every five minutes. The skeletonized dial is designed with oversized Roman numerals as movement bridges, enhancing its architectural appeal. Blued steel hands and a sapphire cabochon-set crown complete the refined aesthetic. The timepiece is fitted with a black alligator leather strap and an 18k white gold deployant clasp. Protected by a sapphire crystal and water-resistant up to 30 meters, this watch is a testament to Cartier’s excellence in fine watchmaking and artistic craftsmanship.
