The Cartier Santos Dumont is an iconic rectangular dress watch, first introduced in 1904 as the world’s first modern wristwatch for aviator Alberto Santos-Dumont. This steel model features a polished stainless steel case with signature exposed screws at each corner, a silvered opaline dial with black Roman numerals and blued-steel sword-shaped hands, and the 'CARTIER' logo at 12 o’clock. The 27.5mm x 34mm case houses a quartz movement (Caliber 430 MC), ensuring precision and reliability. It is paired with a black alligator leather strap with deployant clasp, offering refined elegance and comfort. The watch rests on a red velvet cushion beside its official International Guarantee card—printed in France, serial number 4213360813ZX, reference WSSA0032—confirming authenticity and activation eligibility. Ideal for formal events, business settings, or sophisticated daily wear, the Santos Dumont blends heritage craftsmanship with timeless minimalism. Its clean lines, legible dial, and understated luxury make it a quintessential unisex timepiece for discerning collectors and connoisseurs of horological design.
