18k Gold & Steel - Automatic - Vintage Box Few timepieces capture the bold, geometric experimentation of the 1980s like the Cartier Santos Octagon. Reference 0907 represents the "Petit Modèle" (Small Model) execution of this avant-garde design, distinguished by its eight-sided 18k yellow gold bezel and the legendary integrated bracelet. While the majority of ladies' Cartier watches from this era were equipped with quartz movements, this specific reference houses a Swiss automatic (self-winding) movement. This makes it a rare find for the collector who values mechanical horology within the refined dimensions of a classic jewelry watch. The white lacquer dial is the quintessential Cartier canvas, featuring crisp Roman numerals, the railroad minute track, and blued-steel sword hands. This example is in great vintage condition. The case and bracelet exhibit sharp edges and original finishes, with only minimal signs of age and time marks consistent with careful handling over the decades (as detailed in the provided photography). The bracelet is tight and retains its industrial character, while the 18k yellow gold screws provide the perfect warm contrast to the brushed steel. The Collector's Highlights: • Mechanical Sophistication: A rare opportunity to own a small-form Cartier with an automatic movement, offering a sweeping seconds hand and a mechanical soul. • Geometric Avant-Garde: The Octagon is a sophisticated departure from the square Santos, offering a unique "octo-round" silhouette that remains highly modern today. • Preservation: Maintaining "great" condition with only minimal marks, this piece serves as an excellent candidate for a curated vintage collection. • The "Godron" Bracelet: Featuring the iconic integrated design where the links flow seamlessly into the case, secured by the signature gold screws. • The Set: Accompanied by its original Cartier presentation box, an essential component for completeness.
