Solar Dial And Non-animal Material Strap - Cartier Tank Must

The latest solar-powered dial (no need to replace the battery, can replace the quartz movement) matched with the Cartier Tank Must watch embodies Cartier's vision: to improve the quality of life and the experience of Cartier customers. Cartier successfully applied the photoelectric principle to the dial of the Tank watch, while retaining the original design aesthetic. At the heart of this technological feat are delicate, nearly invisible, hollowed-out holes in the Roman numeral hour markers, through which solar energy can pass to the photovoltaic cells below the dial. The development team took two years of research and development to create this SolarBeat movement, which has an average service life of about 16 years https://www.tocowatch.co/.

The Tank Must is the first Cartier timepiece to be equipped with this movement. This watch is also groundbreaking with an innovative material strap, which is produced in a process that reduces the carbon footprint (divide by 6), saves water (up to 10 litres) and energy (up to 7 litres) compared to producing calfskin straps megajoules, equivalent to about 200 smartphone charges).

Cartier has chosen to give preference to local sources of supply: recycling apple-growing waste in Europe, processing raw materials in Italy, making watch straps in Portugal, and assembling watches in Switzerland.
