Cartier Rotonde de Cartier Mysterious Hour White Gold / Baguette

The Cartier Rotonde de Cartier Day & Night HPI00890 is a stunning expression of Cartier’s artistic craftsmanship, combining poetic complications with high jewelry design. The 40mm 18k white gold case is fully set with brilliant-cut diamonds, covering the bezel, lugs, and case sides for a dazzling effect. Powered by the Cartier Caliber 9912 MC, a manual-winding movement, this timepiece features an elegant day-and-night complication, where the sun and moon travel across the upper half of the silvered guilloché dial, transitioning between day and night. The lower half of the dial hosts a retrograde minutes display, creating a visually dynamic aesthetic. Roman numerals and blued steel sword-shaped hands maintain Cartier’s signature look. A fluted crown, set with a sapphire cabochon, enhances the luxurious appeal. The watch is paired with a black alligator leather strap, secured with an 18k white gold ardillon buckle. A sapphire crystal protects the dial, while the timepiece is water-resistant up to 30 meters. This Rotonde model is a perfect blend of horological expertise and high jewelry refinement.
