Introduced in 2021 to update their movement tech, the Must SolarBeat integrates photovoltaic technology into the traditional Tank profile. The solar cells are positioned beneath the dial, absorbing ambient light through invisible micro-perforations cut directly into the black Roman numerals.
The stainless steel case maintains the established proportions, featuring mirrored brancards and a beaded crown set with a blue synthetic spinel. The caliber is highly efficient and designed to operate continuously for over a decade before requiring factory maintenance.
Founded in Paris in 1847, Cartier approaches horology with the perspective of a master jeweler, prioritizing form, proportion, and aesthetic purity. The Maison was a crucial pioneer of the modern wristwatch, creating the purpose-built Santos-Dumont in 1904 for aviator Alberto Santos-Dumont and later the iconic Tank in 1917, whose "brancards" seamlessly integrated the case and lugs into a singular design.
While historically collaborating with ebauche movement suppliers, Cartier has since invested significantly in its own manufacture capabilities in Switzerland, developing a suite of in-house calibres. The brand's enduring significance lies not in technical innovation, but in creating a portfolio of iconic case shapes that are foundational to watchmaking itself.
