The Cartier Santos-Dumont Extra Large (Ref. WSSA0032) honours the revolutionary 1904 collaboration between Louis Cartier and Brazilian aviator Alberto Santos-Dumont that produced one of the first purpose-designed wristwatches, now in its most substantial proportions at 46.6mm x 33.9mm. The Manufacture Calibre 430 MC with manual winding delivers an authentic mechanical experience through hand-winding that connects directly to the origins of the Santos as a practical instrument for flight, whilst the ultra-slim 7.5mm thickness creates effortless elegance under a shirt cuff.

At 46.6mm x 33.9mm with 7.5mm thickness through stainless steel construction, this provides commanding rectangular presence that scales the iconic Santos geometry to its most dramatic proportions whilst the extraordinary thinness ensures refined wrist presence rather than bulk. The rounded angles of the dial, seamless horn curves, and exposed screws that defined the 1904 original remain central to the design whilst the silver satin-finish dial with sunray effect and blued-steel sword-shaped hands create unmistakable Cartier aesthetic refinement.

The Manufacture Calibre 430 MC delivers precise manual-winding mechanical operation through Cartier’s own movement construction, providing the intimate connection of hand-winding appropriate to a watch of this historical significance. The beaded steel crown set with blue cabochon synthetic spinel creates a distinctive detail consistent across the Santos family whilst the square-shaped sapphire crystal protects the Roman numeral dial.

The navy blue alligator leather strap with steel ardillon buckle creates sophisticated presentation appropriate to the Santos-Dumont’s dress watch character whilst the 30m water resistance covers everyday requirements. The steel caseback maintains slim proportions whilst the extra-large format makes this the Santos for those who want the full visual impact of the rectangular case at its most expansive.
