The Cartier Santos-Dumont watch has the distinct historical credentials of being the world's first pilot wristwatch made by Louis Cartier in 1904 for his friend, the Brazilian aviator, Alberto Santos-Dumont. This elegant and contemporary skeletonised model is housed in a rich, rose gold case that measures 38.7 by 47.4mm, with a sapphire-set hexagonal crown. The skeletonised dial forms Roman numerals from the rose gold bridges showing the movement beneath, with blued-steel hour and minute hands marking the time. The manual-winding movement, calibre 9614 MC, provides a power reserve of up to 72 hours and is water-resistant to 30m. Worn on a brown alligator leather strap, the Cartier Santos-Dumont Skeleton watch is secured with a rose gold double adjustable deployant buckle.
