Tank Must SolarBeat Steel Silver Dial 22mm

The Cartier Tank Must SolarBeat ref. WSTA0089 reimagines an icon through sustainable innovation. This 22mm small model features a polished stainless steel case and is powered by Cartier’s SolarBeat photovoltaic movement, which captures light through invisible perforations in the dial to ensure long-lasting, maintenance-free performance.

The silvered dial displays black Roman numerals, blued-steel sword-shaped hands, and a classic minute track, reflecting the timeless elegance of the Tank line. A beaded crown set with a synthetic cabochon-shaped spinel completes the refined design.

Paired with a black calfskin strap and stainless steel ardillon buckle, the Tank Must SolarBeat offers comfort and understated style. Water-resistant to 30 meters, this model blends Cartier’s signature aesthetics with forward-thinking watchmaking, embodying both tradition and innovation in a modern form.
