Born from an illustrious heritage of aviation history, the Santos de Cartier Medium Model (MM) stands as a modern evolution of the world's very first purpose-built wrist watch, originally created in 1904 for aviator Alberto Santos-Dumont. This magnificent iteration takes the classic geometric square architecture and elevates it into the realm of high jewelry, framing its sunray silver dial with a brilliant bezel set with 206 hand-selected diamonds. Combining industrial stainless steel strength with breathtaking luxury, it commands an undeniable presence on the wrist.
