Cartier Tank Must Solar

Introduced in the late 1970s, Cartier reissues the Tank Must this year with a new collection of timepieces. Our favorite model of the collection is a version that happens to be their first solar-powered model ever. The watch features their SolarBeat photovoltaic movement that feeds off of solar power to charge the watch and has a lifespan of over 16 years. The watch is charged through solar energy that is fed through small perforations in the dial's Roman numerals to power the photovoltaic cells underneath. The company also created a new strap that uses waste from apples grown in Europe to create a leather alternative that meets the brand's criteria for quality and comfort. 

Available this September.
