"A legend was born” when Louis Cartier created the first 'Tank' prototype in 1917 – every variation of the iconic watch developed since preserves the design integrity of that original. With the same clean lines, this ‘Must’ version has been made in Switzerland from stainless steel. The hallmark details are the blued-steel sword-shaped hands, Roman numerals and a beaded crown set with a cabochon spinel.For warranty information, please refer to details & care
