The Cartier Tank is one of Cartier’s most iconic watch collections, first introduced in 1917 and inspired by the design of World War I military tanks—specifically the shape of their tracks. It features a clean, rectangular case, bold Roman numerals, and a railroad-style minute track, creating a timeless and elegant aesthetic. Worn by numerous cultural icons over the decades, the Tank is celebrated for its minimalist design, historical significance, and enduring appeal in both men's and women's fashion.
