Cartier Tank Tank Must de Cartier

Tank Must de Cartier – the gateway to the Tank

The Tank Must traces its origins to the “Les Must de Cartier” line of the 1970s, with which Cartier opened up the Tank to a wider audience. Since 2021 it has been available again in a new edition: A steel case in the classic shape of 1917, Roman numerals, blued steel hands and a crown set with a spinel cabochon. At HORANDO you will find the Tank Must in the small, large and XL models, new and unworn with the full manufacturer's warranty.

Quartz, SolarBeat or automatic

Most Tank Must models are powered by a high-autonomy quartz movement that runs for years without a battery change. In the SolarBeat version, light charges the movement through the dial, so there is no need for a battery change at the usual intervals. The XL model has a mechanical automatic movement with a date window at 6 o'clock, making it the Tank for anyone who wants to wear mechanics on the wrist. All models are water-resistant to 30 metres.

Which size suits you

The small model measures 22 by 29.5 mm and is particularly popular with women. The large model, at 25.5 by 33.7 mm, is the classic Tank size for women and men, while the XL model, at 31 by 41 mm, has a noticeably bolder presence and suits larger wrists. Alongside the silver dial on a black calfskin strap, the Tank Must is available with a black lacquered dial and alligator strap as well as with a steel bracelet.

The Tank Must in comparison

If you would like more gold, the Tank Louis Cartier is the classic gold version. With an integrated link bracelet, the Tank Française is the alternative, while the more elongated and slender option is the Tank Américaine. You will find all lines on our page dedicated to the Cartier Tank. Which rectangular watches from other brands compete with the Tank is shown in our guide Cartier Tank alternatives.
