Cartier dates the Santos-Dumont to 1904 and says Louis Cartier answered the wish of the Brazilian aviator Alberto Santos Dumont to read the time while flying. This skeleton version has brilliant-cut diamonds on the case, bezel, crown, bridges, micro-rotor and buckle.

The movement is the automatic calibre 9631 MC, 23.9 mm across and 4.7 mm thick, with a power reserve of approximately 44 hours. The micro-rotor has mother-of-pearl and is set with 37 brilliant-cut diamonds totalling 0.1 carats.
