Cartier Tank Must Large WSTA0109 2025 [Preowned]

Overview

The Cartier Tank Must Large reference WSTA0109 sits at a specific point in the current Tank catalogue. The Must line was relaunched in 2021 as a reference to the original Must de Cartier range of the 1970s — the series that extended Cartier's design vocabulary to a wider market. The Large is the size that works for buyers who find the traditional Tank proportions too restricted for a modern wearing context.

The 33.7mm x 25.5mm steel case carries the Tank's defining architecture: rectangular brancards, flat profile on the wrist, and a vertical case form that has not materially changed since 1917. The silvered dial runs black Roman numerals, a rail-track minute perimeter, and blued-steel sword hands — an arrangement Cartier has not altered because altering it would be incorrect. A blue synthetic sapphire cabochon is set in the crown. The strap is grained black calfskin, secured with a polished steel tang buckle.

The movement is quartz — appropriate for a dress watch in this category that will be worn selectively and stored between occasions.

Secondary prices on the Tank Must Large have held since the 2021 relaunch — the reintroduction brought durable attention to the Must line rather than the typical new-reference spike and correction. Preowned, excellent condition, complete with box and papers dated June 2025, at RM12,300.
