Cartier Santos-Dumont XL Skeleton

About This Watch

The Cartier Santos-Dumont XL Skeleton in 18k rose gold is a breathtaking marriage of Cartier's oldest wristwatch design with haute horlogerie skeletonization. The extra-large case provides a generous canvas for the exquisite caliber 9612 MC, a hand-wound movement whose bridges have been meticulously shaped to form Roman numerals — Cartier's signature approach to skeleton design that maintains legibility while showcasing mechanical artistry. The warm tone of the rose gold case amplifies the visual warmth of the exposed movement, creating an almost organic quality as light plays through the openworked bridges. Despite the 46.6mm diagonal measurement, the rectangular proportions and remarkably thin 8.25mm profile ensure it sits gracefully on the wrist rather than dominating it. The 72-hour power reserve is exceptionally generous for a skeletonized manual movement. Each component is finished by hand — beveled edges, circular graining on the mainplate, and blue screws that add pops of color against the rose gold bridges. The dark brown alligator strap provides a classical counterpoint to the avant-garde dial. This is Cartier at its most ambitious: taking a design born in 1904 and proving that it can serve as a vehicle for 21st-century haute horlogerie without losing a molecule of its original charm.
