Cartier Santos Octogonale 2965: an automatic steel watch with a white dial

This Cartier Santos Octogonale Watch, reference 2965, is an iconic piece from the 1980s, with an all-steel octagonal case. It stands out for its octagonal bezel with visible screws, a signature of the Parisian house's bold geometric design — a chic response to the spirit of the sport-luxury watches of the era. Its classic white dial, adorned with Roman numerals and blued sword hands, is complemented by a date window at 3 o'clock. With balanced proportions, it wears equally well on a man's or a woman's wrist. A true Cartier icon.

The white dial highlights the black Roman numerals and a peripheral minute track, in the purest Cartier DNA. The blued sword hands add a touch of elegance and a lovely contrast, while the date window at 3 o'clock brings genuine everyday practicality. The blue cabochon crown, another signature of the house, completes the whole. A classic and refined dial, with perfect legibility.

At the heart of this Santos beats a Swiss automatic movement (ETA base), with automatic winding and date. Beating at 28,800 vibrations per hour, it offers a power reserve of approximately 38 hours. Protected by its sapphire Crystal, this watch combines Cartier elegance with the reliability of a proven mechanical movement. Fully serviced in July 2025, it is ready to be worn every day.

With its 29mm octagonal case in steel and its original integrated steel bracelet with visible screws, this Santos offers ideal proportions and an immediately recognizable silhouette, on a man's wrist as much as a woman's — a true Unisex watch. The sapphire Crystal shows two micro-scratches at the center (8/10) and the whole has been serviced. The bracelet adjusts to approximately 16.5cm (additional links available on request).

Frequently asked questions

What is the Cartier Santos Octogonale?
The Santos Octagon is a variation of the famous Santos line by Cartier, introduced in the late 1970s. It stands out for its octagonal case and bezel with visible screws, in a geometric sport-chic spirit. Reference 2965, in steel and with automatic movement, is one of its most sought-after versions.

It is powered by a Swiss automatic movement (ETA base), with date, beating at 28,800 vibrations per hour and offering a power reserve of approximately 38 hours. Reliable and proven, it was fully serviced in July 2025 and is guaranteed for 1 year.

Is the watch delivered with its box and papers?
No. This Santos is delivered without its original box or papers. It does, however, come with the Atelier Victor invoice, attesting to its authenticity, and a protective case for transport and storage.

Is this watch water-resistant?
This is a vintage watch: although the Santos was designed with a certain degree of water resistance, water resistance can no longer be guaranteed today without replacing the seals. We recommend avoiding any contact with water without prior servicing.

Is this watch suitable for a man or a woman?
It is a Unisex watch. Its 29mm octagonal case is an ideal size for wear that is both masculine and feminine. Its white dial with Roman numerals and iconic design make it an elegant piece for any occasion.
