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.

The case is particularly large for a 1920s watch, with the rectangular curved case sitting incredibly well on the wrist, showcasing Cartier's eye for design and proportions. Even the clasp displays the same number as the case, attesting to the fact it was delivered to the watch.

Interestingly, it is most probable that the timepiece was made in France and sold in London, as seen by the French hallmarks on the case and the two dots flanking the outside case number, which is a sign the watch was retailed in London. Yet the design of the dial remains firmly "London" with the exploding Roman numerals and the absence of the outer track on the dial. This shows that during the early part of the 20th century, the different branches of Cartier (London, New York and France) were working with each other and not operating in silos, whether it be by sharing designs, stock and production among the three Cartier brothers.
