Tank Must extra-large stainless steel watch

In 1917, Louis Cartier created the first prototype of the 'Tank' watch, drawing inspiration from the streamlined shape of a military vehicle viewed from above. This Swiss-made 'Must' variation is crafted from stainless steel and has a silvered flinqué dial with blued-steel sword-shaped hands and Roman numerals. The cabochon spinel at the crown is a signature detail.
