Six were made in 1919. A century later it is still the shape of quiet money. In 1919 Cartier put a new wristwatch into full production and made just six of them. Louis Cartier, grandson of the house's founder, had drawn it in 1917 from the outline of a Renault tank on the Western Front. More than a century later, that rectangle is still the default answer to what a man wears with a suit. ## How do you get a watch from a tank? You look at it from above. The Renault FT had two long tracks running down either side of a boxy hull, and Cartier's case did the same thing at small scale. The vertical side bars, which Cartier calls brancards, are said to stand in for the treads. The dial sits between them like the crew compartment. Revolution notes that the case also grew out of the earlier square Santos, so the Tank was less a lightning strike than a jeweler pushing a shape he already liked to its logical end. The legend that comes attached is that Cartier presented a prototype to General John J. Pershing, commander of the American Expeditionary Force. It is the kind of origin story a brand would invent if it did not already have one, and it has been repeated so often that it now functions as part of the product. ![A white pocket watch photographed in low light](https://images.unsplash.com/photo-1453574487790-de3ecc4ffc4a?w=1600&h=1067&q=80&auto=format&fit=crop) *Before the Tank, a serious man's watch still lived in his waistcoat pocket.

In 1917 most men still carried a pocket watch, and the wristwatch had a reputation as something for women or for soldiers who needed both hands. A flat rectangle from Cartier, shaped after a weapon, made the wrist look like the correct place for a gentleman's watch. It did not shout about it. That restraint is the whole design. ## The 1920s were a run of variations Production was tiny at first, six watches in 1919 and only a trickle after that. Then Cartier started playing. The Tank Cintrée arrived in 1921, stretched and curved to follow the wrist. The Tank Chinoise followed in 1922, with extra bars across the top and bottom that borrow from the gateways of East Asian temples. The same year brought the Tank Louis Cartier, the softened, rounded version that the house now treats as the standard. Rudolph Valentino reportedly refused to take his off while filming The Son of the Sheik in 1926, giving the Tank its first screen role. Fred Astaire bought a Cintrée in 1928. Duke Ellington wore a Tank à Guichets, a version with small windows for jumping hours and minutes instead of hands. The 1930s got stranger. The 1932 Tank Basculante had a case that pivoted to protect the crystal, and the 1936 Tank Asymétrique slanted the whole dial. Then the money dried up. Revolution reports that Cartier's wristwatch output fell from about 500 a year in the 1920s to 130 during the Depression. Louis Cartier died in 1942, and for decades the Tank coasted on the shapes he had already drawn. ## Who wore it, and why it stuck The list of owners reads like a seating chart for the twentieth century. Jacqueline Kennedy wore one. So did Yves Saint Laurent. Princess Diana was photographed again and again with a gold Tank Française, and in 2009 Michelle Obama wore a steel Française in her official portrait as First Lady. Andy Warhol had the best line on the subject, and it is worth paraphrasing rather than quoting. He wore his Tank because it was the watch to wear, and by his own account he never bothered to wind it. Telling the time was beside the point. That is the most honest review a dress watch has ever received. The reason it works on such different people is that it gives almost nothing away. No bezel, no crown guards, no logo you can read across a room. On the classic models you get Roman numerals, a railroad minute track, blued hands and a cabochon on the crown. It pairs with tailoring the way an [Oxford cloth button-down](https://quietmenace.com/style/oxford-cloth-button-down-history/) pairs with a navy blazer, as a background you stop noticing. ## Must, Américaine, Française and back again The modern Tank lineup was built in three moves. In 1977 the Must de Cartier line put the shape in vermeil, gold over silver, with flat lacquered dials in deep red and later blue and black. It was cheaper, and it introduced the Tank to a buyer who would never have walked into a Cartier boutique for a gold watch. The Tank Américaine came in 1989 with a longer, curved case. The Tank Française followed in 1996 with a steel bracelet built into the case, and became the version a whole generation pictures first. In spring 2021 Cartier brought the Must back as the Tank Must, again in monochrome red, blue and green dials that echo the 1977 run. The surprise was the SolarBeat model, which hides photovoltaic cells under the dial so the quartz movement charges from light, with a stated lifespan of around 16 years. Compare it with the Genta school of the 1970s, where steel sports watches like the [Audemars Piguet Royal Oak](https://quietmenace.com/watches/audemars-piguet-royal-oak-history/) put screws and integrated bracelets on show, or the tool-first logic of the [Omega Speedmaster](https://quietmenace.com/watches/omega-speedmaster-moonwatch/). The Tank asks for none of that. It sits closer to the reduction in [Dieter Rams's ten principles](https://quietmenace.com/design/dieter-rams-ten-principles/) than to anything else in a watch case.

The detail that still lands is the count. Six watches in 1919, made for a handful of people who had no idea they were buying the template for a hundred years of rectangles. --- Filed under: [Watch History](https://quietmenace.com/topics/watch-history/), [Heritage Brands](https://quietmenace.com/topics/heritage-brands/), [Luxury Fashion](https://quietmenace.com/topics/luxury-fashion/) Hero image: Photo by Caramel on Unsplash (Unsplash License)
