The Cartier Santos-Dumont is one of the most historically significant wristwatch designs, with its origins dating back to 1904 when Louis Cartier created a wristwatch for his friend, the Brazilian aviator Alberto Santos-Dumont. Frustrated by the impracticality of retrieving a pocket watch while flying, Santos-Dumont sought a more convenient means of telling the time, prompting Cartier to develop what would become one of the earliest purpose-built men's wristwatches. Its distinctive square case, exposed screws and geometric proportions were a radical departure from the predominantly round pocket watches of the period, establishing a design language that has remained remarkably consistent for more than a century.
While the Santos would eventually evolve into a more robust sports watch, the Santos-Dumont has remained the more elegant and traditionally proportioned interpretation of the original design. Reintroduced in 2019 as a dedicated collection, the modern Santos-Dumont retains the thin case, understated proportions and classical appearance of its historical predecessors, while Cartier has gradually expanded the collection through increasingly elaborate materials, decorative techniques and limited editions.
Introduced in 2024, the reference WGSA0096 forms part of a trio of limited-edition Santos-Dumont watches distinguished by their lacquered cases and coloured dials. Offered in yellow gold with taupe grey, rose gold with peacock blue and platinum with olive green, these references represent a particularly unusual interpretation of the Santos-Dumont, incorporating colour directly into the architecture of the case rather than restricting it to the dial. Of the three, the platinum reference is arguably the most distinctive, pairing the cool tones of the precious metal with a rich olive green lacquer finish. Produced in a limited edition of just 200 individually numbered examples, it is also a relatively rare variation of the modern Santos-Dumont.
The platinum case measures 43.5mm by 31.4mm, with a thickness of just 7.3mm, retaining the wonderfully slim proportions that have become synonymous with the Santos-Dumont. The familiar square bezel is decorated with a translucent olive green lacquer, applied in an exceptionally thin layer measuring less than one thousandth of a millimetre before being carefully smoothed and hand-polished. The lacquer follows the contours of the bezel, framing the dial while leaving the exposed screws and polished platinum surfaces visible.
The dial is equally attractive, featuring a sunray-brushed olive green surface with stylised Arabic numerals that follow the rounded corners of the case. Unlike the more conventional Roman numerals associated with Cartier, the Arabic numerals lend the watch a slightly more contemporary appearance, while their elongated proportions complement the geometry of the dial. A pair of polished, rhodium-plated sword-shaped hands provides a restrained contrast against the green surface, with the absence of a seconds hand preserving the clean, symmetrical layout. Completing the design is a beaded platinum crown set with a red cabochon ruby.
Powering the watch is the manually wound Cartier calibre 430 MC, an ultra-thin movement based on the Piaget calibre 430P. Measuring approximately 2.1mm in thickness, the movement offers a power reserve of around 38 hours and allows Cartier to maintain the exceptionally slender case profile. The solid platinum caseback is engraved with the handwritten signature of Alberto Santos-Dumont, a fitting tribute to the aviator whose friendship with Louis Cartier gave rise to the original watch.
What I find particularly appealing about this Santos Dumont is how Cartier has managed to introduce a relatively unconventional material treatment into one of its most established designs without disturbing its original proportions. The olive green lacquer is not merely decorative, but serves to emphasise the square geometry of the case, while the matching dial and green alligator strap create a remarkably cohesive appearance. The platinum construction, ruby-set crown and limited production of just 200 pieces further distinguish it from the regular Santos-Dumont collection. It is a particularly successful example of Cartier's ability to reinterpret a century-old design through subtle changes in colour, material and finishing, while retaining the proportions and architectural clarity that made the original Santos-Dumont so enduring.
