Powered by Cartier's caliber 1904 CH MC, this extra-large Santos chronograph houses a mechanical movement with automatic winding within a steel case measuring 43.3 mm wide and 12.5 mm thick. A sapphire crystal protects the satin-brushed silver dial, while black steel sword-shaped hands carry luminescent material for low-light legibility. The 7-sided crown is set with a faceted blue synthetic spinel, a signature detail that ties the piece to Cartier's storied design language.
The 18K yellow gold bezel frames the dial with a warm contrast against the steel case, and the watch is water-resistant to 10 bar (approximately 100 meters). It comes equipped with a steel bracelet featuring Cartier's SmartLink adjustment system, as well as a second rubber strap, both fitted with the QuickSwitch interchangeability system and a steel folding buckle for effortless swapping between wear styles.
Reference W2SA0008 represents the Santos collection in one of its most technically accomplished expressions, pairing the iconic square silhouette with the practicality of dual straps and the functionality of a chronograph complication.
