Cartier WHSA0043 Santos Dumont YG

Cartier Santos-Dumont Micro-Rotor Skeleton in 18K yellow gold with automatic 9629 MC movement, sapphire cabochon crown, skeleton bridges and 44-hour power reserve.

Crafted in 18K yellow gold (750/1000), the large model case measures 43.5 mm x 31.4 mm with a slim 8 mm profile, preserving the elegant proportions that define the Santos-Dumont line. The beaded 18K yellow gold crown is set with a signature sapphire cabochon, while golden-finish sword-shaped hands glide above an architectural openworked dial. The bridges, coated in beige lacquer, form the Roman numeral structure, an aesthetic and technical signature that merges form with function. Sapphire crystal and a sapphire caseback reveal the intricate mechanics within.

At its heart beats the automatic mechanical calibre 9629 MC, equipped with a micro-rotor to maintain the watch’s refined thinness. Measuring 23.2 mm in diameter and 4.4 mm thick, the movement operates at 28,800 vibrations per hour and delivers approximately 44 hours of power reserve.
