War Machine Turned Wrist Jewel
In 1917, Louis Cartier looked at a Renault FT light tank — the first modern tank design with a rotating turret — and saw a watch. The rectangular case represented the tank’s body viewed from above. The vertical side bars (brancards) represented the treads. The rounded ends of the case represented the turret. It was one of the most unlikely leaps of industrial design imagination in history: a weapon of war became an object of beauty.
Cartier presented the first Tank watch to General John J. Pershing, commander of American Expeditionary Forces in Europe, in 1918. Commercial production began in 1919. Over a century later, the Cartier Tank remains the most iconic rectangular watch ever made — and arguably the single most important non-round watch in horological history.
The Tank Family: Every Variant You Need to Know
Tank Louis Cartier (1922-Present)
The “pure” Tank — closest to Louis Cartier’s original vision. Rounded brancards, slightly curved case, sapphire cabochon crown. Available only in gold (yellow, white, or rose) — never in steel, maintaining its luxury positioning. The current Ref. WGTA0011 (large, 33.7 × 25.5mm) uses the manufacture Caliber 1847 MC automatic. Retail: ~$13,500 (yellow gold).
This is the Tank for purists — the one Jackie Kennedy wore, the one Princess Diana chose over her Patek, and the one that graces the MoMA permanent collection as a design icon.
Tank Française (1996, Relaunched 2023)
The commercial blockbuster. Cartier introduced the Tank Française with an integrated bracelet — a radical departure from strap-only Tanks. The bracelet links echo the case’s rectangular proportions, creating a seamless wrist-hugging design that became Cartier’s best-selling watch of the late 1990s and early 2000s.
The 2023 relaunch refined the proportions with a thinner case (6.8mm), updated movement, and new dial textures. Available in steel (from ~$3,900), two-tone, and gold. The steel Française is the most accessible Cartier Tank and an excellent entry into the brand.
Tank Américaine (1989-Present)
A larger, curved Tank designed for the American market (hence the name). The case curves along the wrist axis — a technically challenging construction that requires bending the sapphire crystal. The Américaine is the most masculine Tank variant: at 45mm × 26mm (large), it has the proportions of a small baguette rather than a square. Available in gold only. Retail: ~$20,000+.
Tank Must (2021-Present)
Cartier’s sustainability and accessibility play. The “Must” name revives Cartier’s 1977 “Les Must de Cartier” line that brought the brand to a wider audience. The 2021 Tank Must features a steel case, interchangeable strap system, and — controversially — a SolarBeat™ photovoltaic movement in some references that uses light to charge a capacitor, eliminating battery changes for 16+ years.
- Small (29.5 × 22mm): Quartz. ~$2,650
- Large (33.7 × 25.5mm): Quartz or SolarBeat. ~$3,100
- Large Automatic (33.7 × 25.5mm): Caliber 1847 MC. ~$4,500
The Tank Must is the smart entry point: Cartier’s most iconic design, in steel, at an accessible price, with the option of an automatic movement for mechanical enthusiasts.
Tank Solo (2004-2021, Now Replaced by Must)
The Tank Solo was the previous entry-level Tank — quartz or automatic, steel or gold. Discontinued and replaced by the Tank Must in 2021. Pre-owned Solos trade at $1,800-$3,000 and represent excellent value.
Quartz vs Automatic: The Tank Debate
Unlike most luxury watch purchases, the Cartier Tank is one case where quartz might be the right choice. Here’s why:
- Thinness: Quartz Tanks are significantly thinner than automatics — crucial for a dress watch designed to slip under a cuff.
- Accuracy: Quartz is 100x more accurate than mechanical (±15 seconds/month vs ±5 seconds/day).
- No winding needed: For a watch you might wear 2-3 times a week, not having to wind or reset is a genuine convenience.
- Heritage: Cartier has always used quartz in many Tank references — it’s not “lesser” in the Tank world the way it would be in a Rolex or Patek.
That said, the automatic Caliber 1847 MC (available in Tank Must Large and Tank Louis Cartier) is a proper in-house manufacture movement, and for mechanical watch enthusiasts, it’s the way to go.
The Tank as Cultural Icon
- Jackie Kennedy: Wore a Tank Louis Cartier throughout the White House years — arguably the most photographed watch of the 1960s
- Princess Diana: Chose the Tank Française as her signature watch, wearing it publicly for years before and after the divorce
- Andy Warhol: Famously said “I don’t wear a Tank watch to tell the time. I wear it because it’s the watch to wear.”
- Muhammad Ali: Wore a gold Tank during press conferences
- Yves Saint Laurent: Lifelong Tank wearer — it defined the intersection of fashion and horology
- Kim Kardashian: Wears a vintage Tank Américaine, contributing to the Tank’s renewed popularity among Gen Z and millennials

Frequently Asked Questions
Is the Tank a men’s or women’s watch?
Both. The Tank was designed in an era before gendered sizing existed. The Small Tank (29.5mm) skews female; the Large (33.7mm) and Américaine (45mm) skew male; the Française works for everyone. The Tank is perhaps the most genuinely unisex luxury watch in existence.
Will a quartz Tank hold value?
Yes — Cartier Tanks hold value regardless of movement type because the design, not the mechanics, drives the value. A quartz Tank Must bought at $2,650 will trade at $1,800-$2,200 pre-owned, which is typical luxury-watch depreciation.
Is 30m water resistance enough?
For a dress watch, yes. 30m means handwashing, rain, and accidental splashes. Don’t swim with it, don’t shower with it. The Tank isn’t a sports watch — treat it accordingly.
Do you carry Tank superclones?
Yes — our Cartier collection at DR.WATCH includes Tank references in steel and gold-tone with Swiss quartz or automatic movements. The signature brancards, Roman numeral dial, and sapphire cabochon crown are faithfully reproduced. Free worldwide shipping + 1-year warranty.
