This vintage Cartier Santos Ronde ref. 81913 is an elegant two-tone timepiece from the 1980s–90s, combining stainless steel with an 18kt yellow gold bezel and characteristic gold screws. The round 27 mm case features Cartier’s signature octagonal crown set with a blue cabochon, while the white dial is beautifully detailed with painted Roman numerals, a railway-style minute track and elegant blued-steel sword hands. Protected by a sapphire crystal, the watch is powered by the reliable Cartier Calibre 81 quartz movement. Its integrated steel and gold bracelet with deployant clasp completes the refined and unmistakably Cartier design. A timeless vintage interpretation of the iconic Santos aesthetic.
