Modelled on the timepiece Louis Cartier used to wear himself, the Tank Must watch is, and will remain, one of the Maison’s most enduring icons. Here, the ‘70s-style design is revived for a new generation of watch connoisseurs with its steel case and all the usual Cartier signatures: the Roman numeral white dial, the railway minute track, the blue sword-shaped hands, and the blue stone cabochon set into the crown. Quartz-powered and both timeless and contemporary at once, it’s a ‘must’-have addition to your accessories edit.
