Description
The Tank Must line, introduced in the late 1970s, was Cartier’s effort to make the Tank more accessible while retaining its timeless elegance. The 2021 WSTA0051 revives this heritage with a clean, minimalist design that pays homage to the original Louis Cartier Tank of 1917. By combining the classic Tank silhouette with modern materials and quartz technology, Cartier created a watch that balances tradition with practicality. Today, the Tank Must is celebrated as a gateway into Cartier’s watchmaking universe — a piece that embodies Parisian chic, understated luxury, and the enduring appeal of the Tank design across generations.
