Powered by the calibre 1847 MC mechanical automatic movement, the medium Santos de Cartier is housed in a steel case 35.1mm wide and 8.83mm thick, topped by a sapphire crystal. The 7-sided crown is set with a faceted synthetic spinel, while steel sword-shaped hands sweep across the silvered opaline dial.
Two bracelet options are included: a steel bracelet featuring the SmartLink adjustment system, and a calfskin bracelet with an interchangeable steel folding buckle. Both attach via Cartier's QuickSwitch interchangeability system, allowing a swift and tool-free swap between the two.
The watch is water-resistant to 10 bar, approximately 100 metres, making it as practical as it is refined. Reference WSSA0029 is a medium-model Santos that balances the icon's architectural heritage with everyday wearability.
