The Cartier Santos WGSA0030 stands apart as the medium full yellow gold expression of Cartier’s most important shaped watch. Its 35.1 mm case and 8.82 mm profile keep the proportions close to the Santos design language, while the exposed bezel screws, square case, Roman dial, minute track and blued hands retain the codes collectors look for. The model’s roots sit in 1904, when Cartier created a wristwatch for aviator Alberto Santos Dumont.
