Louis Cartier designed the Tank in 1917, supposedly inspired by the outline of WWI tanks seen from above. More than a century later, it’s still the defining rectangular watch. The modern Tank Must is the most affordable way into it. It has Roman numerals, a railway minute track and the blue cabochon crown, in a steel case that’s comfortable and thin.
