Cartier Tank

The Cartier Tank survives by its details rather than by one fixed shape. Louis Cartier drew it in 1917 from the plan view of the Renault FT-17, turning the tank's tracks into two parallel brancards, and in the century since Cartier has curved it, stretched it, squared it, plated it and put quartz inside it. Across the classic branches, a Tank is still read from the same few details: brancards, Roman numerals, a railway-track minute ring, blued hands and a cabochon on the crown.

The watch was conceived in 1917 and sold from 1919. A prototype went to General John J. Pershing, generally dated 1918, but he was the famous early recipient rather than the intended customer. Cartier aimed at civilians for whom the wristwatch, made familiar by soldiers in the First World War, could be a refined object instead of a field tool, and early Tanks went to industrialists, artists, royals and actors.

The line then grew by branching rather than by replacement, and most branches were design decisions, not answers to any documented supplier or regulatory event. The elongated Cintrée of 1921 curved the case to follow the wrist, the Louis Cartier (1921 by Cartier's own dating, 1922 in other histories) softened its corners, and interwar forms such as the reversible Basculante traded the plain rectangle for protection.

The clearest commercial reason arrived in 1977 with the vermeil Must de Cartier Tank, a cheaper way into the same outline. Later branches, from the curved Américaine of 1988 to the bracelet Française of 1996 and the steel Tanks that followed, kept the same vocabulary while changing the case around it.

That is how the Tank outlived the fashions it was made in: Cartier kept the vocabulary fixed and let the case, the metal and the movement change around it.

For daily wear, the steel branch is the natural home: the 2021 Tank Must WSTA0041 is its current form, steel and quartz, and the Solo 3169 is the same idea from the generation before.

For a Tank on a bracelet, the Française is the branch, and its sizes run from the small quartz 2384 through the midsize 2301 to the automatic 2302, with the 2303 chronograph beside them.

For a first vintage piece, the family's documented entry point is the Must, whose vermeil case and frequent quartz movement kept it accessible; the 590005 is a quartz example.

The archetype is the gold Louis Cartier: the hand-wound 78086 from the 1970s revival, or the rose-gold hand-wound WGTA0011 for the same idea new from Cartier, with the small yellow-gold W1529856 as its quartz form.

The family's reference-collector target lies beyond these pages. It is the vintage Cintrée, which Hodinkee describes as the most desirable variant (a market judgment rather than a fixed fact), and it is the Tank that most rewards patience: by Hodinkee's count, Cartier made fewer than 2,000 Tanks of all kinds between 1920 and 1960.

Buying across the Tank family means buying very different constructions that share one vocabulary, so a correct watch is defined by internal consistency rather than by any single marker. For several vintage references the available record gives no exact production years, which leaves dealer and auction dates as estimates and puts the burden of proof on the watch itself. GQ's verdict on surviving 1970s Must Tanks, plating usually worn and quartz movements often exhausted, is the family's buying problem in miniature: the outline survives far more often than the watch inside it.
