Introduced in the early 1980s following the success of Cartier’s collaboration with S.L. Dupont on a collection of co-branded lighters that ended up securing Cartier’s financial future, the Tank Must de Cartier collection was a diffusion line that leveraged the Cartier Tank’s iconic silhouette and Cartier’s legendary branding in a more affordable package so as to offer customers the same look as before but at a more palatable price tag. Launched under the Tank Must’s original principles, the ref. WSTA0059 that we have here debuted in 2022 as a marriage of modern watchmaking and Cartier’s classical aesthetic. Boasting a rectangular 33.7mm x 25.5mm stainless steel case and a silver dial with all of Cartier’s signature design elements, the modern Tank Must de Cartier ref. WSTA0059 harbors just about as much of Cartier’s design language as it can. Distinctively ‘Cartier’ with its cabochon sapphire crown, iconic design and overall aesthetic, this legendary horological design is as timeless as they come. However, modernizing the WSTA0059 is a silver dial that goes beyond being just a norma; dial. Instead, it is a photovoltaic SolarBeat™ dial which absorbs light through its Roman numerals which the watch then uses to charge its battery, ensuring that this quartz timepiece is about as hands-off as a watch can get.

Watch is in near-mint condition. Case shows minor signs of use, with some surface debris trapped along some of the case edges.

A wonderfully executed blend of timeless watchmaking and modern engineering, the WSTA0059 showcases just how brands can still be innovative without the need to create wacky complications that offer very little practical value to the wearer.
