The Cartier Santos Dumont stands as one of the most important creations in watchmaking history, originally designed in 1904 for aviator Alberto Santos-Dumont. This 1970s reference 7809 embodies the timeless elegance and refined geometry that have long defined the Santos line. Its 18K yellow-gold case features crisp edges and harmonious proportions, framing a classic white dial with black Roman numerals, an inner minute track, and blued-steel hands that complete the unmistakable Cartier aesthetic. The sapphire cabochon crown adds a signature touch of sophistication. Inside ticks the manual-wind caliber 78/1, based on Jaeger-LeCoultre’s renowned 2512-1 movement. Paired with a black leather Cartier strap, this piece captures the essence of the Santos: an icon that merges historical importance, elegant design, and mechanical finesse.
