The Santos-Dumont XL is the large rectangular Santos in its truest form: manual-wind, steel, 47mm, and built to recall the proportions of the 1904 original. There is no automatic rotor adding bulk, no complications diluting the idea. Just a flat, clean rectangle you wear on your wrist because Alberto Santos-Dumont needed to read the time with both hands on the controls.
In 1904, Louis Cartier made a wristwatch for his friend Alberto Santos-Dumont, the Brazilian aviator who was then astonishing Paris by flying powered aircraft over the Bois de Boulogne. Santos-Dumont could not check a pocket watch mid-flight, so Cartier strapped a watch to his wrist. That makes the Santos the first purpose-built men's wristwatch on record, not a converted brooch or a military affectation.
The WSSA0032 revisits the original brief: large, flat, rectangular, and hand-wound, the shape that started the category. Cartier introduced the modern Santos-Dumont XL in 2018 as a conscious step away from the sportier, automatic Santos de Cartier line. It sits apart in the catalog for collectors who want the historical version, not the contemporary sport interpretation.
The 47mm length sounds imposing but is a rectangular case, so wrist presence reads differently than a 47mm round watch. Measure your wrist and consider the lug-to-lug fit before assuming it is too large. The manual-wind 1611 MC requires daily winding; if you wear the watch intermittently you will reset the time more often than an automatic wearer expects.
Early WSSA0032 examples from 2018 and 2019 were produced with a synthetic strap only; later examples added more strap options at purchase. The flat case means crystal replacement on a knocking or scuffed watch will be a recurring service cost, so inspect the crystal carefully on any pre-owned piece. Verify the caseback seal and crown tube condition on secondhand examples, as the rectangular case makes resealing more labor-intensive than a round case.
New retail is approximately $6,500 to $7,500 depending on strap configuration and region. Pre-owned examples trade in the $4,500 to $6,000 range with light use. This ref does not attract the same speculative premium as the Santos de Cartier automatic, which means the secondary market is calmer and a patient buyer can find fair pricing without competing against flippers.
Service history matters more here than on an automatic, so ask sellers specifically whether the manual movement has been serviced.
The caliber 1611 MC is a Cartier in-house manual-wind movement with a roughly 40-hour power reserve. Cartier recommends service intervals of approximately four to five years for this caliber. Cartier boutiques and their authorized network handle it, or an independent watchmaker with Cartier experience can service the 1611 MC without issue, as it is a straightforward manual movement with no exotic complications.

Rectangular case proportions are difficult to counterfeit precisely; Cal. 1611 MC manual-wind and case dimensions are the primary checks.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| movement | Cal. 1611 MC manual-wind identification | Watch is manually wound only; no rotor visible through exhibition caseback; winding via crown adds power reserve; Cal. 1611 MC text or architecture visible; 72-hour power reserve | Rotor visible through caseback (indicates automatic, not Cal. 1611 MC); watch that self-winds with wrist motion; caseback showing any automatic movement |
| case | 43.5x31.4mm rectangular dimensions | Case length approximately 43.5mm, width approximately 31.4mm; case is slim (ultra-thin profile); stepped rectangular case with polished surfaces and brushed flanks | Dimensions significantly different from 43.5x31.4mm; case that is excessively thick (should be slim); case proportions that appear square rather than elongated |
| dial | Rectangular dial Roman numerals | Roman numerals are scaled and spaced for the rectangular dial format; Cartier typeface maintained; "CARTIER" signature and "SANTOS-DUMONT" text present; blued steel sword hands | Numerals that appear compressed or stretched for the rectangular format; Cartier text with wrong typeface; hands that are black or silver rather than blued steel |
| crown | Crown with spring mechanism (push-in, not screw-down) | Crown pushes in and springs back; no screw-down crown on this model; blue cabochon on crown top; winding action is smooth and direct | Crown that screws down; absence of blue cabochon; winding that is rough or gritty indicating a worn movement |
| caseback | Exhibition caseback showing Cal. 1611 MC | Cal. 1611 MC plates visible through caseback; no rotor present; movement architecture is flat (ultra-thin); Cartier movement finishing visible on bridges | Rotor present; movement architecture inconsistent with ultra-thin manual-wind; absence of Cartier finishing on bridges |
