Cartier Santos Lady Automatic 0901 – Full Set, Like New Unworn (1987)

A rare time capsule from the golden age of Cartier, the Santos Lady Automatic Ref. 0901 offers the perfect balance of elegance, heritage, and exclusivity. This unworn example, complete with its original box and papers, has been preserved untouched in a bank vault since its purchase in Brussels in 1987—making it a truly once-in-a-lifetime find.

The Iconic Santos Design

Originally designed by Louis Cartier in 1904 for aviator Alberto Santos-Dumont, the Santos line became the world’s first purpose-built wristwatch. Its instantly recognizable square case, exposed screws, and clean geometry remain a timeless expression of sophistication.

This “Lady” size edition from 1987, measuring 34 x 24mm, retains all the hallmarks of the classic Santos while offering a more refined and versatile wrist presence. The steel case remains in unpolished, untouched condition, with the red lacquer on the caseback still perfectly intact—an almost impossible feature to find after nearly 40 years.

The blue sapphire cabochon crown adds the quintessential Cartier touch, while the integrated steel bracelet, sized for up to a 17cm wrist, completes the unmistakable Santos profile.

Cartier Automatic Movement

At its heart beats a reliable Cartier automatic movement, freshly serviced and running with excellent timekeeping performance. Smooth in operation and backed by a one-year warranty, it ensures this piece is as functional as it is collectible.
