A legendary silhouette meets pioneering horology in the Cartier Tank Must SolarBeat™ (Ref. WSTA0121).Rooted in Louis Cartier’s iconic 1917 design, this small-model timepiece seamlessly unites clean Art Deco geometry with modern, sustainable innovation. Beneath its silvered dial lies Cartier’s photovoltaic SolarBeat™ quartz movement, which harnesses natural and artificial light through discreet micro-perforations concealed within the Roman numerals. The result is over a decade of reliable, maintenance-free precision without compromising the maison’s signature aesthetic. The polished stainless steel case measures 29.5 mm by 22 mm with an ultra-slim 6.6 mm profile, accented by Cartier's beaded crown set with a cabochon synthetic blue spinel. Signature blued-steel sword hands sweep across the traditional railway minute track, while an integrated stainless steel link bracelet ensures exceptional versatility and comfort. Water-resistant to 30 meters, the WSTA0121 represents a brilliant, eco-conscious evolution of quintessential Parisian luxury.
