Cartier Tank
Louis Cartier's 1917 rectangular wristwatch inspired by a WWI tank — the template for the rectangular dress watch.
The Cartier Tank is a rectangular wristwatch created by Louis Cartier in 1917 and officially introduced in 1919. The case design was inspired by the top-down profile of the Renault FT tank, which Cartier observed during World War I — the long parallel case bands correspond to the tank's caterpillar tracks, and the rectangular case body to the hull. The original Tank ('Tank Louis Cartier') set the design vocabulary that has been maintained across more than a century: rectangular case, brancards (parallel rail case bands), Roman numeral chapter ring on white dial, blue steel hands, and a leather strap. The Tank is among the longest continuously produced wristwatch designs in history and has been worn by prominent cultural figures including Princess Diana and Andy Warhol.

Design Origins and World War I
Louis Cartier (1875–1942), grandson of the firm's founder, designed the Tank in 1917 while serving as an officer's liaison in the French Army. He gave the first examples to General John J. Pershing, commander of the American Expeditionary Forces, as a gift. The design was not commercially introduced until 1919, after the war's end. The name refers to the Renault FT, the light tank that the Allies deployed in large numbers from 1917 and that became one of the most influential tank designs of the 20th century. The 'brancards' — the flat parallel bands extending from the case body to the strap lugs — are a direct visual reference to the tank's tracks viewed from above.
Tank Variants
The original 1919 design is now termed the Tank Louis Cartier. Subsequent variants include: Tank Americaine (1989, curved case following wrist contour), Tank Francaise (1996, square integrated bracelet), Tank Solo (2004, simplified, quartz-powered entry model), Tank Must (2021, reissued budget variant), Tank Chinoise (1922, wider stepped case), Tank Asymetrique (1936, deliberately asymmetric, very rare), Tank Cintre (1921, curved sides, highly sought vintage). Each variant maintains the brancard aesthetic while modifying case proportions, curve profile, and mechanical specification. The most historically significant are the Tank Louis Cartier and the Tank Cintre.
Notable Owners
The Tank has been worn by an unusually broad spectrum of prominent figures across the 20th century. Andy Warhol wore a Tank and stated that he 'owned' it because it was the only watch he truly desired. Princess Diana wore a Tank Francaise. Muhammad Ali wore a Tank. Jacqueline Kennedy Onassis wore a rectangular Cartier watch reportedly given by her father. Yves Saint Laurent, Coco Chanel, and Humphrey Bogart are all documented Tank owners. The breadth of cultural figures associated with the Tank — spanning arts, politics, athletics, and fashion — is remarkable and distinguishes it from the sport-tool-watch cultural associations of the Submariner or Speedmaster.
Movement and Modern Production
Early Tanks used ébauche movements supplied by Swiss manufacturers — Cartier's Parisian workshops were craftsmen in case finishing and gem-setting rather than movement manufacture. Contemporary Tank references use Cartier manufacture movements: the calibre 430 MC (manual-wind, 2 mm thick, in the Tank Louis Cartier) and calibre 1847 MC (automatic, Tank Solo and Francaise) are produced at Cartier's La Chaux-de-Fonds manufacture. The 430 MC, at 2 mm, is one of the thinnest Swiss manufacture movements in production. Cartier maintains the original Roman numeral dial format (with a discreet railroad minute track at the chapter ring edge), blue steel Breguet-style hands, and the characteristic cabochon sapphire crown — all introduced on the original 1919 reference.

Frequently asked questions
When was the Cartier Tank first produced?
Louis Cartier designed the Tank in 1917 and gave prototypes to General Pershing. The first commercially sold examples were produced in 1919, the year the design was officially introduced to clients. The 1919 date is generally used as the reference point for the Tank's introduction.
What is the difference between Tank Louis Cartier and Tank Solo?
The Tank Louis Cartier is the original rectangular format, produced in gold and using the calibre 430 MC manual-wind movement — Cartier's traditional prestige version. The Tank Solo is a smaller, simplified model introduced in 2004, powered by a quartz movement (calibre 690 or similar) in steel or gold cases, positioned at a lower price point as an entry to the Tank family. The Solo uses the same rectangular-brancard case visual but with reduced case complexity.
What does 'Cartier' refer to in the Tank name?
Tank Louis Cartier specifies the original tank design and is named for Louis Cartier, the designer and third-generation member of the Cartier family who created it. Cartier was founded in Paris in 1847 by Louis-Francois Cartier; subsequent generations — Alfred Cartier (son), and Louis, Pierre, and Jacques Cartier (grandchildren) — expanded the firm internationally. Louis Cartier (1875–1942) is credited with many of the firm's most celebrated designs including the Santos-Dumont wristwatch (1904), the Tonneau (1906), and the Tank (1917).
