Tank Must de Cartier stainless steel and leather watch

Debuted in 1917, Cartier's 'Tank' collection is inspired by the sleek lines and caterpillar tracks of the namesake military vehicle. This 'Must de Cartier' watch is made from stainless steel and accented with a crystal cabochon to match the blued steel sword-shaped hands, which are framed by classic Roman numerals. It rests on a leather strap that will age beautifully over time.
