Cartier Tank Must

The Cartier Tank Must WSTA0041 is one of the most iconic rectangular watch designs in history, created in 1917 by Louis Cartier who was inspired by the Renault tanks he observed on the Western Front during World War I. The Tank has since graced the wrists of Princess Diana, Jacqueline Kennedy Onassis, Andy Warhol, and Muhammad Ali.

Movement

The Calibre 1847 MC quartz movement powers this Tank Must, offering precision timekeeping with a battery life of approximately 38 months. The choice of quartz honours the "Must" line's accessible luxury heritage.
