Introduced in 1921, the Tank Cintrée model was the largest and boldest variation of Cartier’s Tank line. With its long, slender, and gracefully arching case, the Cintrée is without a doubt one of the most beautiful watches made during the 20th century. The Cintrée’s highly curved case was designed to hug the curves of the wrist. The expansive dial and case combine straight lines, sensual curves, and crisp angles, resulting in a "modern" wristwatch with a design far ahead of its time - so much so, in fact, that the design has spawned multiple re-editions; the latest one, released in 2021, being a virtually perfect replica of the vintage model.

Interestingly, it is most probable that the timepiece was sold in London, as seen by the English hallmarks on the case, and was fitted with a "Paris" dial at the same time. It was in 1972 that the Cartier family sold the firm, and it is highly possible that the manufacture used up existing watch parts during the 1970s as they were finishing up their existing stock.

Most interestingly, both the case and the clasp have Cartier hand stamped numbers "1977" showing how the case and clasp were delivered together. In addition, both the case and clasp are stamped with the letter B, indicating London hallmarks that date to 1976. The watch itself is preserved in excellent condition, with crisp hallmarks and engravings throughout. The dial exhibits a beautiful eggshell dial that has turned warm and ivory throughout time.
