The Cartier Santos is one of the most historic Swiss luxury watches, first created in 1904 for aviator Alberto Santos-Dumont and widely regarded as the world’s first modern wristwatch. Defined by its square case, exposed bezel screws, and elegant Roman numerals, the Santos blends functional design with Cartier’s refined aesthetic. Over the years it has evolved into variations such as the Santos de Cartier and Santos-Dumont, available in stainless steel, gold, and two-tone metals. Modern editions feature Cartier’s innovative QuickSwitch bracelet system and precise Swiss automatic movements, offering versatility and contemporary performance. Today, the Cartier Santos remains one of the most important Cartier watches for sale, valued by collectors for its aviation heritage, distinctive design, and lasting place in the history of fine watchmaking.
