Cartier Santos-Dumont Large Steel Gray Skeleton Dial with Micro-Rotor - WHSA0032 - New 2026

The Santos-Dumont Skeleton ref. WHSA0032 is a superlative exhibition of transparency and structural precision. The Large model (43.5 mm x 31.4 mm) remains exceptionally thin at just 8 mm, despite the complexity of its automatic winding system. The defining feature is the Manufacture Calibre 9629 MC, a skeletonized movement where the bridges are meticulously coated in gray lacquer, creating a sophisticated "stealth" look that blends seamlessly with the polished steel case.

At the 7 o’clock position, a functional micro-rotor takes center stage, shaped like a miniature replica of the Demoiselle—the pioneering aircraft designed by Alberto Santos-Dumont in 1907. This oscillating weight appears to glide over the movement as it captures energy from the wearer's wrist. The dial consists of the movement's own gear train and bridges, accented by polished blued-steel sword-shaped hands and a beaded steel crown set with a blue synthetic spinel cabochon. It is presented on a gray alligator leather strap (with an additional blue strap included), utilizing the Cartier QuickSwitch system for effortless strap changes.

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.
