Cartier Tank Must Solarbeat Large Steel Silver Dial WSTA0120 - BRAND NEW

The Cartier Tank Must Solarbeat in stainless steel — reference WSTA0120 — stands as one of the most compelling modern expressions of a design that has defined elegance in watchmaking since 1917. Conceived by Louis Cartier and inspired by the overhead view of a Renault tank traversing the battlefields of World War I, the Tank's rectangular case, parallel brancards, and sapphire cabochon crown have remained virtually unchanged across generations, earning the watch a permanent place in both horological history and popular culture.

The WSTA0120 belongs to the Tank Must line, which Cartier revived and reinvigorated to bring the Tank within reach of a wider audience while maintaining the full weight of the maison's heritage. The "Must" designation carries its own storied legacy, referencing the Must de Cartier collections of the 1970s and 1980s that democratized the brand's iconic shapes. Today the Tank Must continues that mission, and the Large steel reference strikes a precise balance between presence and wearability.

At the heart of this reference is Cartier's Solarbeat photovoltaic movement — a significant technical achievement that harnesses light energy to power the watch, dramatically reducing the frequency of battery replacements and making this one of the most practical luxury dress watches available. The movement is designed for a service interval far beyond that of a conventional quartz watch, reflecting Cartier's commitment to engineering that matches the longevity of its design philosophy.

The silver Roman numeral dial is quintessentially Cartier: the characteristic blued-steel sword hands sweep across a clean silvered surface framed by the stainless steel brancards and bezel, while the sapphire cabochon crown punctuates the profile with the maison's signature detail. The leather strap reinforces the watch's identity as a refined everyday companion, lending a warmth and suppleness at the wrist that complements the cool geometry of the steel case.
