Pioneering designer Louis Cartier imagined the Tortue watch, a tortoise-inspired shape, in 1912. At a time when all watches were round, the groundbreaking design went on to become a classic. Cartier offers both ladies' and men's models in a full range of styles, available in gold, at times set or fully paved with diamonds.
