Cartier Introduces Solar-Powered Tank

Cartier’s new Tank collection includes the brand’s first solar-powered watch. The SolarBeat Tank Must is a slim, square stainless automatic powered by SolarBeat movement. Light that passes through the Roman numerals on the face reaches the photovoltaic charging system to keep it moving. The wrist strap is made of non-animal leather—another sustainability cue from the luxury label.
