Cartier Tank

The Cartier Tank is a line of rectangular dress wristwatches created by the French jeweller and watchmaker Louis Cartier. Conceived in 1917, the design was inspired by the newly introduced Renault military tanks observed on the Western Front during the First World War. Cartier presented an early prototype of the watch to General John J. Pershing of the American Expeditionary Force. Following its introduction in 1918, the timepiece entered full production in 1919, when six pieces were manufactured.

In the early 1920s, Cartier formed a joint-stock company with Edward Jaeger to produce movements exclusively for its timepieces, alongside mechanisms sourced from makers such as Vacheron Constantin, Audemars Piguet, Movado, and LeCoultre. During this same era, the firm began stamping a four-digit reference code onto the underside of a lug. Cartier subsequently expanded the line across several decades, releasing the Tank Louis in 1922, the Tank Américaine in 1989, and the Tank Française in 1996, followed later by variants such as the Tank Anglaise, Tank MC, Tank Solo, and a centenary automatic edition in 2017.

The architecture of the Tank reflects the proportions of First World War battlefield tanks. Its principal case feature consists of parallel vertical sidebars, termed brancards, into which the strap is seamlessly integrated. The dial is distinguished by Roman numerals paired with a railway-style chemin de fer chapter ring, sword-shaped blued steel hands, and a winding crown surmounted by a sapphire cabochon.
