Steeped in horological history, the Tortue de Cartier is one of the maison’s most distinctive and collectible designs. Originally conceived by Louis Cartier in 1912, the tortoise-inspired case introduced a sculptural alternative to traditional round watches, establishing a legacy that continues to resonate today.

Crafted in 18kt white gold, this rare reference features a silver dial with Roman numerals, framed by a diamond-set bezel for a quietly luminous finish. Powered by a hand-wound Cartier Calibre 430 MC movement, the watch reflects refined mechanical artistry paired with enduring design significance.
