Cartier Tank Must Extra Large Automatic Steel Silver Dial Leather Strap WSTA0040

The Cartier Tank Must WSTA0040 is one of the most compelling entries in the modern Cartier catalog — a watch that distills over a century of rectangular watchmaking tradition into a bold, wearable, and unmistakably Parisian package. Introduced as part of Cartier's revitalized Tank Must collection, this extra-large reference is designed for the contemporary collector who wants genuine Swiss luxury with an iconic silhouette that reads effortlessly across dress and smart-casual settings alike.

The Tank lineage traces its origins to 1917, when Louis Cartier drew inspiration from the overhead view of Renault tanks rolling across the Western Front. The elongated rectangular case with protruding parallel rails — the "brancards" — has remained the defining visual grammar of every Tank ever since. The Tank Must line was originally conceived in the 1970s as a more accessible entry point to the Tank family, and its modern relaunch has reaffirmed its status as a cornerstone of the collection, introducing automatic movements to a line historically dominated by quartz calibers.

The WSTA0040 wears an extra-large stainless steel case that gives the Tank Must a commanding wrist presence without straying from the watch's inherently elegant DNA. The stainless steel bezel frames the silver dial with clean, architectural precision, and the Roman numeral hour markers — a hallmark of Cartier dial design — deliver instant brand recognition alongside genuine legibility. The blued-steel hands and the characteristic Cartier minute-track complete a dial that is both timeless and unmistakably modern.

Powering this reference is an automatic movement, a meaningful upgrade from earlier quartz-driven Tank Must models and one that elevates the WSTA0040's long-term desirability among collectors. The watch is presented on a leather strap that complements the case's refined lines and keeps the overall aesthetic firmly in dress-watch territory, while remaining versatile enough for daily wear. Cartier's choice of stainless steel throughout the case and bezel ensures durability and resistance to everyday use without adding unnecessary weight.
