The Cartier Tortue XL reference  W1545951 represents one of the Cartier's most elegant tonneau-inspires creations. It's curved 18K white gold case frames a guilloché silver dial that blends classic proportions with modern functionality. At its heart beats the manual‑wound 9910 MC caliber, an 8‑day movement engineered with JLC, visible through a transparent case back. Fitted on its original black Cartier strap and buckled in white gold, this Tortue exudes sophisticated craftsmanship for true connoisseurs of haute horlogerie.
