Frederique Constant’s Classics Moneta Solarmetre Proves that Solar Power Maybe the Future

A quartz watch delivers flawless, grab-and-go battery accuracy while a mechanical watch offers the soul of traditional, intricate engineering. But what can a solar-powered watch do? Frederique Constant’s Classics Moneta Solarmetre shows us exactly what solar power can achieve. The first reference from the Frederique Constant Manufacture to be equipped with the solar-powered FC-120 calibre, the Classics Moneta Solarmetre serves as an excellent example of what boundary-breaking watchmaking can do without compromising at all on aesthetics.

Debuted in 2024, the Classics Moneta collection is a masterclass in design, drawing its name from the coin-edge fluting along its inner bezel. The new Solarmetre models elevate this aesthetic by keeping their solar technology completely invisible, delivering virtually limitless power while allowing the watch’s refined style to take centre stage.

A New Era of Power

Photovoltaic technology isn’t new to horology, but where mechanical movements struggle to gain a few extra hours of power reserve, solar energy delivers a seamless solution: perpetual operation powered by light. Even in total darkness, it retains 10 months of reserve power, recharges a full day’s energy in just one minute of light and restarts within 10 seconds of exposure.

Until now, solar adoption was hindered by bulky movements and compromised aesthetics. Frederique Constant, alongside its partner La Joux-Perret, solved both problems by developing an ultra-slim, translucent solar movement, a breakthrough showcased in the sleek design of the three new Classics Moneta Solarmetre models.

A Culmination of Firsts

The new Classics Moneta marks a series of milestones for Frederique Constant as the brand’s first solar-powered timepiece, the first Classics Moneta housed in a 39 mm case, the debut of a grained dial in the collection, and the first reference supplied with two quick-change straps: an alligator-embossed leather strap and a refined Milanese mesh bracelet.

Despite these innovations, the watch preserves all of its retro-modern aesthetic codes: a slim profile, fluted flange, faceted applied hour markers and two dauphine hands. A minimalist date window allows the textured dial to breathe, its delicate surface masking the sophisticated three-layer solar construction beneath. At the top, the dial appears opaque but is actually translucent, allowing ambient light to stream through to the middle level, where a photovoltaic cell converts light into electrical energy. Within the watch lies the FC-120 calibre, equipped with a rechargeable battery and an integrated circuit that acts like an energy switchyard, directing power for immediate timekeeping while storing surplus energy to guarantee up to 10 months of continuous operation in total darkness.

Driven by a commitment to relentless innovation, Frederique Constant Manufacture continues to push the boundaries of Swiss watchmaking. The Classics Moneta seamlessly blends refined aesthetics and meticulous hand-finishing with cutting-edge technology, delivering exceptional value without compromise. Defined by its signature coin-edge flange, the Moneta’s distinctive design has quickly become one of the brand's most celebrated hallmarks. Now, with the addition of the Solarmetre variation, it opens limitless horizons for collectors who seek timeless elegance powered by modern ingenuity.
