Santos de Cartier 40 mm Stainless Steel Skeleton with Diamond-Set Case and Bracelet (WHSA0015)

The Santos de Cartier WHSA0015 is an extravagant, fully diamond-set interpretation of Cartier’s iconic square watch. Crafted in stainless steel, this 40 mm skeleton model retains the architectural purity and exposed-screw aesthetic that define the Santos lineage, yet transforms the classic design into a high-jewelry statement through extensive pavé diamond work across the case, bezel, lugs, and bracelet.

The openworked dial reveals the movement’s structure, with bridges styled as elongated Roman numerals — a hallmark of Cartier’s approach to skeletonized watchmaking. Here, the mechanical form is elevated further by pavé diamonds set throughout, creating a seamless interplay of transparency, geometry, and brilliance. The contrast between the technical skeleton architecture and the full diamond setting produces a dramatic, luxurious presence.

With its diamond-set steel bracelet completing the composition, this Santos model stands as a bold fusion of horological artistry and jewelry craftsmanship. It remains faithful to Cartier’s heritage while offering one of the most visually striking expressions within the Santos collection.
