Cartier reimagines one of the most historically important designs in watchmaking with the Santos-Dumont Skeleton Micro-Rotor in 18k rose gold. Named after the aviation pioneer who inspired the first men’s wristwatch in 1904, the reference opens its movement to full view and mounts a tiny golden airplane on the micro-rotor, a nod to Santos-Dumont’s Demoiselle aircraft. Slim and understated, it wears as a refined dress piece built for collectors who love mechanical artistry over noise.

Presents itself in mint condition with little to no signs of wear. Framed by an openworked architecture, the skeleton dial reveals burgundy-lacquered bridges and a spinning micro-rotor shaped like a vintage plane, giving the watch a sense of motion and depth few timepieces can match. Carved from 18k rose gold, the case carries the signature exposed screws of the Santos family and a warm, luminous finish that shifts beautifully as it catches the light. Crowned by a faceted blue cabochon, the crown adds a jewel-like accent, while blued sword-shaped hands travel cleanly across the movement.

Functions include hours and minutes. Time is adjusted using the cabochon crown on the right side of the case. With the crown pushed in, turn it to hand-wind the movement, then pull the crown out to set the hours and minutes and push it back in to resume normal running. Worn regularly, the automatic micro-rotor keeps the watch wound through everyday motion, offering roughly a 44-hour power reserve when fully wound.

Comes as a complete set with the original Cartier outer box and inner presentation box, watch pillow, Cartier Care booklet, and the dated International Limited Warranty card. A second Cartier alligator strap in burgundy accompanies the fitted black alligator strap, both paired with the 18k rose gold Cartier pin buckle.

Owning one of the few pieces that reinterprets where the modern wristwatch began carries a quiet weight that newer icons simply cannot borrow. It is made for the collector who already has the usual grails and now wants something with wit and soul, a watch that dresses up with a tuxedo yet feels just as right under a rolled sleeve on a Sunday drive. For the person who would rather be recognized by the few who truly know than the many who only spot a logo, it is the kind of piece that tends to quietly disappear from the market.
