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.

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.
