Cartier Tortue Perpetual Calendar Watch - 45.6 mm White Gold Case - Black Alligator Strap - W1580048

Presented in unworn condition with its distinctive slate dial and substantial 46mm white gold case, this Cartier Tortue Perpetual Calendar represents one of the maison's most architecturally compelling complications. The elongated tonneau case shape of the Tortue collection, which translates to "turtle" in French, creates an unmistakable silhouette that has defined Cartier's design language since the early 20th century. Reference W1580048 houses the perpetual calendar complication within the curved geometry of the white gold case, creating a technical masterpiece that balances horological sophistication with Cartier's signature aesthetic codes. The black alligator strap provides classical contrast against the precious metal case construction.
