Tank Louis Cartier automatic alligator watch

Debuted by Louis Cartier in 1917, Cartier's timepiece is inspired by the overview image of the tanks from WWI battlefields - note the vertical lines, also known as 'brancards' are meant to represent the treads, while the case is modeled on the terret. Dubbed by the house as a "symbol of understated elegance," this 25.5mm reference is crafted from 18-karat gold and flaunts a sleek red dial with tonal Roman numerals. It's powered by a reliable Swiss-made calibre 1917 MC automatic movement and lasts up to 38 hours. The understated look makes it suitable for casual and formal occasions alike.
