Cartier - Santos Automatic 39.8mm 18-Karat Rose Gold Interchangeable Alligator and Leather Watch, Ref. No. WGSA0011

Brazilian aviator Mr Alberto Santos-Dumont called upon his friend and master jeweller Mr Louis Cartier to create a timepiece that could be used in-flight. More than 100 years on, the 'Santos' model is one of most iconic and elegant watches around. This version has a 39.8mm case crafted from polished 18-karat rose gold and is fitted with an opalescent dial detailed with blue steel sword-shaped hands and Roman numerals. It's finished with an angular seven-sided crown encrusted with a faceted sapphire and has interchangeable alligator and leather straps – the innovative 'QuickSwitch' feature allows you to swap them yourself depending on the occasion.
