Meet the Tortue, a Cartier timepiece with a unique tonneau shape. Its story began in 1912 when Louis Cartier took inspiration from the graceful curves of tortoises. Fast forward to 2015, and we have the Tortue Extra Thin, boasting a 44.95*36.1mm case made of white gold (reference number WGTO0003). Simple yet elegant, this watch is a testament to Cartier's timeless design and craftsmanship.
