Cartier, founded in Paris in 1847, turned jewellery design into wristwatch icons. Louis Cartier drew the Tank in 1917, inspired by the top view of a Renault tank. The Tank Must small model keeps that shape in steel with a quartz movement.

Reference WSTA0051 is the small model Tank Must in stainless steel, measuring 29.5 x 22 mm and 6.6 mm thick. The silvered dial carries painted black Roman numerals, a minute track and sword-shaped hands in blued steel, and shows hours and minutes only. The beaded crown is set with a synthetic spinel cabochon. At its heart beats a Cartier high-autonomy quartz movement. The sapphire crystal sits above the dial. Water resistance is rated to 30 metres. The watch is fitted on a steel bracelet with a folding clasp.

This Cartier Tank Must Small is in near mint condition and comes as a full set with extended factory warranty until 2029.
