Cartier Santos-Dumont Large 18K Rose Gold Skeleton Dial With Micro-Rotor - WHSA0030 - New 2026

The Santos-Dumont Skeleton ref. WHSA0030 is a superlative exhibition of transparency and architectural design. The Large model (43.5 mm x 31.4 mm) maintains an impressively slim 8 mm profile, even with the inclusion of an automatic winding system. The standout feature is the Manufacture Calibre 9629 MC, a skeletonized movement where the bridges are meticulously finished with burgundy lacquer to match the warm tones of the 18k rose gold case.

Between the 7 and 8 o’clock positions lies the soul of the watch: a functional micro-rotor fashioned into a miniature gold replica of the Demoiselle, the trailblazing aircraft designed by Alberto Santos-Dumont in 1907. This oscillating weight appears to "fly" over the globe-themed bridges as it powers the watch. The dial is essentially the movement itself, punctuated by blued-steel sword-shaped hands and a beaded crown set with a sapphire cabochon. It is presented on a burgundy alligator strap with a second brown alligator strap included, both featuring the Cartier QuickSwitch system.

The Cartier Santos-Dumont collection represents the birth of the modern wristwatch. Originally designed by Louis Cartier in 1904 for his friend, the legendary aviator Alberto Santos-Dumont, it was the first timepiece specifically engineered to be worn on the wrist to help a pilot check the time while flying. Distinguished by its signature square bezel with exposed screws and its ultra-slim silhouette, the Santos-Dumont remains a global icon of early 20th-century aviation history and Art Deco elegance.
