Cartier Tank
The Cartier Tank is the most consequential rectangular watch in history. Designed by Louis Cartier in 1917, inspired by the Renault FT tank silhouette seen on the Western Front, and worn since by Jackie Kennedy, Andy Warhol, Steve McQueen, Princess Diana, and Michelle Obama. The Tank Louis Cartier, Tank Must, Tank Française, Tank Américaine, and Tank Cintrée span a hundred years of restrained elegance.
