The Cartier Tortue was first introduced in 1912, breaking away from the traditional round watch shape with its distinctive tortoise-inspired case shape. Originally designed for women, the Tortue has since been developed in various models for both genders, becoming a symbol of Cartier's innovative and classic design ethos. Available in precious materials like gold and platinum, the Tortue line features manual movements and showcases Cartier's craftsmanship in watchmaking.
