The Cartier Tank | family history
Louis Cartier designed the Tank in 1917, inspired by the Renault FT-17 tanks he saw on the Western Front. The case parallels became the 'bracelet bar' side pieces; the whole architecture of the watch case as a continuous wrist ornament rather than a bezel-plus-case came from that observation. The watch Louis gave to General John Pershing in 1918 is the direct ancestor of every Tank in this catalog. The Tank catalog policy here covers only mechanical references: manual-wind and automatic. The quartz Tank Must and quartz Tank Solo that dominated retail from the 1980s through the 2000s are excluded. The mechanical variants are thinner, more interesting to wind, and hold their secondary-market value differently.

1917–1990 · The original Tank and the pre-modern variants
Louis Cartier's original 1917 Tank was yellow gold, manually wound, and given as a personal gift. Commercial sale began in 1919. The Tank Normale (the first commercial model), Tank Cintrée (curved case, 1920s), and the elongated proportions variants defined the pre-war era. Through the postwar decades Cartier maintained the design with minimal changes; the Tank is the rare case of a watch that did not need to evolve. Vintage examples are in the fine-watch auction market; not in the catalog.
No references from this era in the catalog yet.
1973–present · The Tank LC (Louis Cartier): the canonical modern reference
The Tank Louis Cartier (WGTA0011) is the mechanical heir to the 1917 original: white or yellow gold case, caliber 1917 MC (manual-wind, thin), Roman dial, blued-steel hands. The 'LC' designation refers to Louis Cartier specifically; it is the prestige tier of the Tank family. The current WGTA0011 is 25.5mm wide, which is small even by dress-watch standards, and the case height of 6.7mm makes it one of the thinnest watches in the catalog. This is the Tank that watchmakers and designers recommend when asked for a single reference.
1996–2012, 2020–present · The Tank Française: integrated bracelet modernization
The Tank Française (WJTA0046) added an integrated metal bracelet with the characteristic curved links and a slightly more robust 30m water resistance. It was the Tank for buyers who found the classic strap too formal. Discontinued in 2012, reissued in 2023 in updated form. The current Française uses caliber 1853 MC (automatic with date). Wears more like a sport-dress watch than the LC; less thin, more contemporary.
2018–present · The Tank Must (mechanical): the accessible entry
The Tank Must (CRWSTA0058, steel, manual-wind, caliber 1917 MC) is Cartier's answer to buyers who want the Tank architecture in steel at a more accessible price point. The 'Must' name comes from the 1970s quartz era when Cartier launched the Must de Cartier line in silver-over-brass as the affordable Tank; the modern mechanical Must is steel and fully in-house. Roman numeral dial, leather strap, the essential Tank vocabulary. It is not a lesser watch; it is the right entry point for buyers whose budget is not gold.
2021, 2023 · The Privé editions: Normale and Cintrée
The Cartier Privé collection revived the original Tank Normale (WGTA0109, platinum, 2023) and the curved Tank Cintrée (WGTA0095, platinum, 2021) as limited annual editions. The Cintrée's curved case follows the wrist in a way no other watch in the catalog does; the platinum and ultra-thin caliber 9780 MC make it the most technically precise Tank available. These are collector references at collector prices.
How to read this family
Three honest questions for any Tank buyer:
- Tank LC, Must, or Française? The LC is gold, thin, and the prestige reference: the correct Tank for someone who wants the original design executed properly. The Must is steel, thin, manual-wind, and the right entry point for most buyers. The Française is automatic, broader, with an integrated bracelet; it is the Tank for people who find the classic strap too formal. These are genuinely different watches serving different buyers; they are not a quality hierarchy.
- How small is the Tank LC, really? The WGTA0011 is 25.5mm wide and 33.7mm long. That is small. It is smaller than most women's watches on the current market. It is the right size for the historical proportions and the right proportions for the wrist as a jewelry-adjacent object. If you have a 7-inch wrist and prefer something that 'fills' the wrist, look at the Tank Must Large (WSTA0041, 33.7 x 41mm) or the Française instead.
- Manual-wind or automatic Tank? Manual-wind is the correct answer for the thin Tank variants (LC, Must small, Cintrée). The movements are thinner and the case height stays honest to the design. Automatic Tanks (Française, Must Large) add a rotor and a few millimeters of height; the trade-off is convenience. If you do not mind winding, manual-wind keeps the proportions.

Sub-lines
- OpenThe dressier Tank sub-line with rounded brancards (the rails flanking the dial). Distinct from the Tank Solo, Tank Must, Tank Américaine, and Tank Française: softer line, gold-only in the canonical refs.
- OpenThe 1996 re-design of the Tank with the integrated metal-bracelet that drops directly into the case: squarer-than-LC brancards, sportier register. The 2023 WJTA0046 / WGTA0102 generation revived the model with quick-change strap-and-bracelet and the cal. 1853 MC automatic in the medium-and-large sizes.
- OpenThe Tank with the curved (cintrée) case, drawn out lengthwise and contoured to the wrist. Originally a 1921 design, reissued under the Cartier Privé program in 2018 and 2021 in platinum, yellow gold, and rose gold limited runs. The longest Tank silhouette in the contemporary catalog.
- OpenThe elongated Tank with the curved, body-hugging case introduced in 1989. Longer than the Tank Louis Cartier but narrower than the Cintree, the Americaine is the right-angled silhouette adapted to the American preference for a bracelet-integrated case. Available in steel, yellow gold, and two-tone.
- OpenThe 2023 Cartier Privé revival of the original 1917 Tank Normale: a wider, squarer case than the Tank Louis Cartier, drawn directly to Louis Cartier’s first-edition proportions. The platinum WGTA0109 and yellow-gold WGTA0108 carry the hand-wound cal. 1917 MC; the line is the Tank closest to the 1917 archetype.
- OpenThe entry-tier Tank line, first launched 1977 with quartz movements and a gold-plated case at the lowest Tank price band. The 2021 Tank Must relaunch (WSTA0041) introduced an automatic version with the in-house cal. 1847 MC in steel, sitting in the modern catalog as the Tank a buyer cross-shops against the Tudor 1926 and the Longines Master.

Which ref to buy
The Tank invented the rectangular dress watch concept in 1919 and the family has never lost relevance -- but the hierarchy of which ref to buy is clear once you know what you are optimizing for.
- 1Open
Tank Louis Cartier: the ur-Tank with correct proportions, cal. 430 manual wind, and the reference every other Tank is measured against.
- The case for it:
- The LC proportions are the original and the benchmark. Cal. 430 is thin, historically appropriate, and still serviced by Cartier. There is no more correct Tank.
- Consider instead if:
- The LC is manual wind and requires attention. The Tank Must Large Auto delivers automatic convenience in a very similar visual package.
- 2Open
Steel Tank Must at accessible pricing -- the correct Tank for buyers who want the look without the Louis Cartier premium.
- The case for it:
- Steel case, correct Tank proportions, and multiple movement options including solar cell. The best entry to the Tank family at genuine value.
- Consider instead if:
- The gold LC is the better collector piece. The Must is a great watch but not a collector acquisition.
- 3Open
Larger automatic-movement Tank Must -- the best value proposition in the current Cartier lineup.
- The case for it:
- Automatic movement removes the winding requirement while keeping the Must price point. The larger case reads better on most wrists.
- Consider instead if:
- If proportions matter to you, the slightly smaller Must or the LC are more historically correct Tank shapes.
- 4Open
Curved case Tank that adds dimensionality to the rectangular silhouette -- for buyers who want something beyond the flat Tank.
- The case for it:
- The Americaine curve is more comfortable on the wrist than the flat LC and creates a different visual impression.
- Consider instead if:
- The flat Tank is the historical design. The Americaine is a variation that some find adds complexity where simplicity is the point.
- 5Open
Integrated bracelet Tank for buyers who want something more sportif than the traditional strap configuration.
- The case for it:
- The Francaise integrated bracelet is well-executed and creates a more casual, everyday feel. Specific clientele who want bracelet wearability.
- Consider instead if:
- The integrated bracelet changes the essential Tank character. The standard strap configurations are more versatile.
- 6Open
Private collection deeply curved Tank -- historically significant, bespoke pricing, museum-quality rarity.
- The case for it:
- The Cintree is a technically ambitious piece with deep case curvature that creates a genuinely unusual wearing experience.
- Consider instead if:
- Bespoke pricing and extremely limited availability. A collector acquisition, not a purchase recommendation.
- 7Open
Original 1919 Tank proportions in the private collection -- the historically first Tank, extremely rare.
- The case for it:
- This is the actual original Tank design from 1919. For serious Cartier historians and collectors only.
- Consider instead if:
- Museum-level rarity means museum-level prices and near-zero secondary market. Wonderful if you can access it.
