Cartier WSTA0122 Tank Must SolarBeat SS Silver Dial

The Cartier Tank Must SolarBeat WSTA0122 is a compelling modern reinterpretation of the iconic Tank design, powered by Cartier’s photovoltaic SolarBeat movement. Housed in a sleek stainless steel rectangular case measuring 33.7 mm by 25.5 mm with a slender 6.6 mm profile, this large model preserves the Tank’s timeless geometry while embracing sustainable innovation. The silvered dial features micro‑perforated Roman numerals allowing light to penetrate and charge the movement below, complemented by blued‑steel sword hands and a beaded crown set with a synthetic cabochon‑shaped spinel. Water‑resistant to 3 bar (approximately 30 meters), the watch carries a refined presence that belies its technical sophistication. Though not a limited edition, the SolarBeat variant stands out in the Tank Must line for its eco‑friendly quartz caliber and collector interest in Cartier’s forward‑thinking approach to energy. Its movement, the SolarBeat photovoltaic quartz, offers longevity and low maintenance—an appealing proposition for enthusiasts valuing both heritage and innovation. This piece bridges Cartier’s storied history with modern watchmaking, offering a subtle yet meaningful twist on a classic. Like New with Cartier box, cleaning kit, and undated papers.
