Cartier Diamonds Yellow Gold Grain de Riz Tank Wristwatch, circa 1970

With its longer case, rounded lugs and slender brancards, the Tank Louis Cartier watch is a distinctive variation on the original Tank, which recalls the boxy military machine for which it is named.

The Tank Louis Cartier was designed in 1922 by Louis Cartier (1875–1942), the grandson of Louis-François Cartier, who, in 1847, established the legendary jewelry house in Paris that bears their family name. Louis is credited with helping to strengthen the brand’s global reach and introducing timepieces to Cartier’s repertoire. 

The Tank Louis Cartier was a modern and simple update to the now-legendary original Cartier Tank, which was designed to mimic the French Renault FT-17 light tanks that Louis saw during World War I — the original’s case is reminiscent of the vehicle’s cockpit, while its brancards resemble tank treads. Cartier conceived of the timepiece in 1917, and a limited production of six watches went on sale in 1919. The initial run of handmade watches sold quickly, and production ramped up. It soon became a favorite of the era’s celebrities, like actor Rudolph Valentino, who wore the timepiece throughout the entirety of the 1926 silent film The Son of the Sheik, despite it being a blatant anachronism. 

The unisex Tank embodies a stark geometry inspired by technology — it could be considered a precursor to the popular Art Deco style. While the Tank Louis Cartier retained the original’s sapphire cabochon, Roman numerals and blued-steel sword-shaped hands, the variation dispensed with the prominently rigid angles of its forebear and added the softer contours that characterize the design of the beloved Tank Francaise, introduced in 1996, as well as all other contemporary Tank watches. 

For its extraordinary range of bracelets, watches, rings and other adornments, French luxury house Cartier is undeniably one of the most well known and internationally revered jewelers in the world among clients both existing and aspirational.

Perhaps 1847 was not the ideal time to open a new watchmaking and jewelry business, as the French Revolution was not kind to the aristocracy who could afford such luxuries. Nevertheless, it was the year Louis-François Cartier (1819–1904) — who was born into poverty — founded his eponymous empire, assuming control of the workshop of watchmaker Adolphe Picard, under whom he had previously been employed as an assistant. Of course, in the beginning, it was a relatively modest affair, but by the late 1850s, Cartier had its first royal client, Princess Mathilde Bonaparte, niece of Napoleon Bonaparte, who commissioned the jeweler to design brooches, earrings and other accessories.

Under the leadership of Louis-François’s son, Alfred, who took over in 1874, business boomed. Royalty around the world wore Cartier pieces, including Tsar Nicholas II of Russia, the Maharaja of Patiala and King Edward VII, who had 27 tiaras made by the jewelry house for his coronation in 1902 and issued Cartier a royal warrant in 1904. (Today, the British royal family still dons Cartier pieces; Kate Middleton, Duchess of Cambridge, regularly sports a Ballon Bleu de Cartier watch.)

Cartier’s golden years, however, began when Alfred introduced his three sons, Louis, Pierre and Jacques, to the business. The brothers expanded Cartier globally: Louis reigned in Paris, Pierre in New York and Jacques in London, ensuring their brand’s consistency at their branches across the world. The trio also brought in such talents as Charles Jacqueau and Jeanne Toussaint.

One of Cartier’s earliest major successes was the Santos de Cartier watch — one of the world's first modern wristwatches for men. (Previously, a large number of people were using only pocket watches.) Louis designed the timepiece in 1904 for his friend, popular Brazilian aviator Alberto Santos-Dumont, who wanted to be able to check the time more easily while flying.

Cartier’s other famous timepieces include the Tank watch, which was inspired by the linear form of military tanks during World War I, and the so-called mystery clocks. Invented by watchmaker and magician Jean-Eugène Robert-Houdin and later crafted exclusively for Cartier in the house’s workshop by watchmaker Maurice Couët, the mystery clocks were so named because the integration of glass dials on which the clocks’ hands would seemingly float as well as structures that are hidden away within the base give the illusion that they operate without machinery.

On the jewelry side of the business, Cartier’s internationally renowned offerings include the Tutti Frutti collection, which featured colorful carved gemstones inspired by Jacques’s trip to India and grew in popularity during the Art Deco years; the panthère motif, which has been incorporated into everything from brooches to rings; and the Love bracelet, a minimal, modernist locking bangle inspired by medieval chastity belts that transformed fine jewelry.

While the Cartier family sold the business following the death of Pierre in 1964, the brand continues to innovate today, renewing old hits and creating new masterpieces.
