Illustration. The seconds hand ticks, as most quartz movements do.
Why it's interesting
Louis Cartier's 1917 rectangle, reduced to steel, a silvered dial, Roman numerals and blued hands — with a quartz movement that happily waits in a drawer for weeks. It is the most direct route into the shape every dress-watch designer has been redrawing for a century.

About this page
Partly verified, checked September 2026
Most specifications were checked against the sources below. Fields that couldn't be confirmed are noted or left blank.
WSTA0041 (the reference suggested) no longer appears on Cartier's German, French or US sites; WSTA0136 is the current large steel quartz Tank Must with a silvered dial on black leather, with identical published specs. Dimensions (33.7 × 25.5 mm; diameterMm = case width, lugToLugMm = case length), 6.6 mm, 3 bar, calibre 157 and price from Cartier Germany. Sapphire crystal from The 1916 Company's WSTA0041 listing — not stated by Cartier. Lug width not published. Drawing: the Tank's brancards and blue cabochon crown are approximated, the Roman numerals sit on an ellipse inside the rectangle rather than following its edges (hours and minutes only, as on the real watch).
