In 2025, Cartier will launch the brand new Tank Must watch, which must be a TANK. Among all the classic Cartier Tank watches, if I had to choose one for everyday wear, I would definitely opt for the TANK Solo. However, this may change with the latest TANK MUST in 2025. This year, the entirely new Tank Must series of watches has been introduced. The Tank Must features the iconic square case measuring 29.5mm x 22mm, a silver-plated dial, sword-shaped blue steel hands, and a unique blue spinel design set in the crown, along with a grained calfskin strap. Compared to its predecessors, the lines are more rounded and fluid. Additionally, the watch is equipped with a quick-release strap function, which greatly enhances comfort and convenience for daily wear.
