Powered by calibre 1847 MC, an automatic mechanical movement, this medium Santos de Cartier houses itself within a 35.1mm steel case measuring 8.83mm thick. The steel bezel is set with 206 brilliant-cut diamonds totalling 0.64 carat, while the 7-sided crown features a faceted synthetic spinel. A sapphire crystal protects the sunray dial below, which is read by blued-steel sword-shaped hands.
Versatility is built into the design through Cartier's QuickSwitch interchangeable system. The watch ships with a steel bracelet featuring the SmartLink adjustment system alongside a second strap in calfskin, both sharing an interchangeable steel folding buckle. Water resistance is rated to 10 bar, approximately 100 metres.
Reference W4SA0005 sits within Cartier's enduring Santos collection, blending the line's architectural case geometry with diamond-set refinement suited to everyday wear.
