18k Gold & Steel - Quartz - "Honest Vintage" Condition The Cartier Santos Octagon remains one of the most distinctive and avant-garde chapters in the history of the Santos collection. Introduced in the 1980s as a creative departure from the square "Carrée," the Octagon (reference 187902) features an eight-sided bezel and a matching octagonal case that many collectors view as Cartier’s sophisticated answer to the integrated-bracelet sports watch era. This is the Large Model (LM), measuring approximately 29mm (excluding the crown). It features the classic two-tone aesthetic, pairing a brushed stainless steel case with a solid 18k yellow gold octagonal bezel. The dial is the quintessential Cartier white/opaline, featuring crisp Roman numerals, the "secret signature" at VII, and a date aperture at 3 o'clock. This timepiece is presented in good vintage condition. True to its history as a daily luxury companion, it exhibits obvious and visible signs of wear throughout the case and bracelet, including surface scratches and hairlines. Notably, there is visible oxidation (rust) within the lug area, a common occurrence in vintage Santos models where moisture can settle between the case and the integrated bracelet pins over decades. This is an "honest" survivor that retains its original factory lines and has not been over-polished. The watch is powered by a high-precision Swiss Quartz movement, offering the "grab-and-go" convenience and slim profile that defined Cartier’s luxury offering in the 1990s. The Collector's Highlights: • Geometric Rarity: The Octagon is significantly rarer than the standard square Santos, offering a unique profile that bridges the gap between a dress watch and a sports icon. • Honest Aging: For the collector who values authenticity, this piece shows its history clearly, with a "lived-in" patina and visible signs of its 30-year journey. • Ergonomic Design: The 29mm octagonal case wears with more presence than its measurements suggest, sitting flat and comfortably on the wrist. • Signature Hardware: Features the original blued-steel hands and the octagonal crown set with a faceted blue sapphire cabochon.
