Cartier Santos Octagon 2966

Cartier Santos Octagon GM Automatic Gold/Steel Full Set Ref. 2966 from 1985

Presenting a refined and highly collectible Cartier Santos Octagon GM Ref. 2966 from 1985, offered as a complete full set with original box, papers, certificate, warranty card, and service documentation. This reference captures a unique evolution of the iconic Santos design, distinguished by its elegant octagonal bezel and harmonious blend of steel and gold. The Santos Octagon stands as a more uncommon and characterful interpretation of Cartier’s legendary square watch, combining classic Parisian design codes with a slightly sportier, architectural edge. This example, preserved as a full set, represents a rare opportunity for collectors seeking both originality and completeness. Key Features & Highlights Dial Classic Cartier white dial with bold black Roman numerals Elegant chemin de fer minute track Striking blued steel hands, a signature Cartier detail Clean and timeless aesthetic with excellent legibility Case 30 mm gold and stainless steel case (GM size), well-balanced on the wrist Distinctive octagonal yellow gold bezel with exposed screws Classic Santos proportions with a slightly more angular presence Sapphire crystal in good condition Blue sapphire cabochon set in the crown Bracelet Iconic Cartier bi-metal bracelet in steel and yellow gold Signature screw design, seamlessly integrated with the case Approx. 18 cm wrist size Comfortable and instantly recognizable Cartier styling Movement Automatic Cartier Calibre 077 Recently serviced and running excellently Reliable and robust everyday performance Why This Example Stands Out The Santos Octagon is a less commonly seen variation within the Santos family, making it especially appealing to collectors who appreciate subtle deviations from the classic square design. The octagonal bezel adds depth and character while remaining unmistakably Cartier. What truly elevates this piece is its complete full set from 1985, including box, papers, certificate, warranty card, and service documentation—an increasingly rare find for watches of this era. Combined with its strong condition and recently serviced movement, this example offers both collectibility and practicality. A Collector’s Opportunity The Cartier Santos Octagon Ref. 2966 represents a distinctive chapter in the Santos lineage—where classic design meets subtle experimentation. Its full set status, strong vintage appeal, and iconic two-tone aesthetic make it a compelling addition to any Cartier or vintage luxury watch collection. An excellent opportunity to acquire a rare and complete example of this elegant and slightly unconventional Santos.
