The Watch That Saw the 20th Century
Louis Cartier designed the Tank in 1917, inspired by the Renault FT-17 light tank he had seen on the Western Front. The brancards (the vertical bars running along the sides of the case) represent the tank's treads; the case body represents the cockpit. It was a radical departure from every watch shape that preceded it — not round, not square, but rectangular with integrated side bars that flowed into the lugs. The Tank entered production in 1919 and has been in continuous production ever since, making it the longest-running watch design in history. No other watch has been worn by as many defining figures of the 20th century.

The Tank Lineup
Tank Louis (Ref. W1529756 / W1529856) The original. 33.9mm × 29.8mm rectangular case with brancards, Roman numerals, chemin-de-fer chapter ring, and sapphire cabochon crown. Available in yellow gold, rose gold, and platinum. The Tank Louis is the purest expression of Louis Cartier's 1917 design — the one that has changed the least in over a century. Hand-wound caliber 8971 MC (38-hour power reserve). For collectors who want the Tank as it was intended.
Tank Française (Ref. W51005Q4 / W51008Q3) The modern Tank. 36.5mm × 28.15mm with a metal bracelet integrated into the brancards — the only Tank where the bracelet is a structural extension of the case rather than a separate leather strap. Available in steel, steel-gold, and full gold. The Française is the most popular Tank for daily wear and the one that works best as an unisex watch. Reissued in 2023 with a slightly refined case profile.
Tank Must (Ref. WSTA0041) The accessible Tank. 29.5mm × 22mm steel case with caliber 076 (quartz). The Must is the entry point into Tank ownership — the same design vocabulary at a fraction of the mechanical price. Available with a range of dial colors including the celebrated burgundy and navy lacquered versions. For buyers who want the Tank aesthetic without the mechanical premium.

Frequently Asked Questions
Q: Is the Tank a men's or women's watch?
A: Both — and that has been true since 1919. The Tank was one of the first watches worn by both men and women, and it remains genuinely unisex. The Tank Louis in gold reads as a men's dress watch on larger wrists and a women's statement piece on smaller ones. The Française is the most gender-neutral Tank. Choose based on your wrist size and style, not on gender categories.
Q: Quartz or mechanical?
A: The Tank Must (quartz) is the value play — the same design at a fraction of the price. The Tank Louis (hand-wound) is the collector's choice — a mechanical movement visible through the caseback, with the ritual of daily winding. If you value convenience, quartz. If you value horological substance, mechanical.
Q: How does the Tank compare to the Santos?
A: The Santos is square with exposed screws — sporty, structural, masculine. The Tank is rectangular with smooth brancards — elegant, architectural, gender-neutral. The Santos has more wrist presence; the Tank has more design purity. Both are Cartier icons with over a century of history.
