Anchored by a 35.1 mm rose gold 750/1000 case measuring 8.83 mm thick, this medium Santos de Cartier features a bezel set with brilliant-cut diamonds and a 7-sided crown in rose gold 750/1000 topped with a faceted sapphire. The silver sunray-effect dial is read through a sapphire crystal, with blued-steel sword-shaped hands marking the hours in elegant contrast.
Inside, Cartier's calibre 1847 MC mechanical movement with automatic winding keeps the watch running reliably, while water resistance to 10 bar (approximately 100 metres) adds genuine practicality. The reference number WJSA0012 comes fitted with two alligator-skin straps compatible with the QuickSwitch interchangeability system, alongside an interchangeable folding buckle in rose gold 750/1000.
