The Cartier Santos-Dumont Micro-Rotor (ref. HPI01631) reimagines the maison’s iconic pilot's watch with modern transparency and elevated refinement. This high-jewellery iteration in white gold draws the eye with its fully skeletonised dial, where hand-set brilliant-cut diamonds across the bridges offer both structure and spectacle.

Housed in a 31mm white-gold case, the watch is set with additional diamonds across the bezel and lugs, creating a seamless interplay of light and negative space. The calibre 9629 MC, Cartier’s ultra-thin micro-rotor skeleton movement, is on full display, with its platinum rotor cleverly shaped into a stylised replica of Alberto Santos-Dumont’s historic Demoiselle aircraft. With a 44-hour power reserve and water-resistance to 30 m, it balances engineering subtlety with daily-wear capability.

Limited in production and meticulously finished, this reference reflects Cartier’s dual mastery of watchmaking and gem-setting. Both a celebration of aviation heritage and a showcase of contemporary craft, the HPI01631 stands as a rare and collectable statement within the Santos line.
