Created in 1904 for aviator Alberto Santos-Dumont, the Santos de Cartier is known for its square case, visible screws, and clean, geometric lines. Designed for both men and women, it features automatic movement, 100? m water resistance, and anti-magnetic protection. Modern versions include QuickSwitch and SmartLink systems for easy strap adjustment. A skeleton model with Roman numeral bridges adds a bold twist. Timeless and technical, it blends aviation heritage with Cartier elegance. Presented on a robust steel bracelet, it features a 40mm case and is water-resistant to 100m. All Cartier watches come with a two-year international guarantee, which can be extended to eight years through Cartier Care, unlocking exclusive benefits and services.
