Frederique Constant Introduces the Classics Moneta Solarmetre

The Classics Moneta Solarmetre becomes the first reference from the Frederique Constant Manufacture to be equipped with the solar-powered FC-120 calibre, developed by La Joux-Perret Manufacture. Launched in 2024, the Classics Moneta collection is a pure exercise in style: its flange is inspired by the fluted edge of a coin — hence its name. Today, the complete invisibility of the solar process enhances its design. Technology fades into the background, autonomy becomes potentially perpetual, and innovation sets the Solarmetre models apart from their counterparts. This includes the new 39 mm case diameter and the collection’s first grained-effect dial, available in three versions: ice blue, burgundy, or cloud white. Each watch is delivered with both a leather strap and a Milanese mesh bracelet.

For five centuries, watchmaking has pursued one quest: perpetual motion. While mechanical movements now seem destined to gain only a few additional hours of power reserve, Solarmetre technology provides the ultimate answer: as long as there is light, the watch will run. In complete darkness, it guarantees 10 months of autonomy. Once exposed to light again, it needs only 10 seconds to restart. Just one minute of exposure is enough to recharge the energy required for a full day of operation.

The principle of photovoltaic energy is not new in watchmaking. However, two major issues had until now limited its widespread adoption: bulkiness and less-than-appealing aesthetics. Together with its partner La Joux-Perret, Frederique Constant Manufacture has overcome both obstacles. The solar movement is slim, and its technology is translucent. The three new Classics Moneta Solarmetre models are proof of this.

This new Classics Moneta introduces numerous “firsts.” They are the first Frederique Constant watches equipped with solar technology; the first Classics Moneta references in 39 mm; the first grained-effect dial in the range; and the first delivered with two interchangeable straps—a leather strap with alligator pattern and an elegant Milanese mesh bracelet.

All the retro-modern aesthetic codes are preserved: the slim case, the fluted flange, the two dauphine hands, and the faceted applied indexes. A simple date window allows the grained-effect dial to breathe, its delicate surface revealing nothing of the solar technology it conceals. Yet it is carefully integrated within, layered across three levels. The uppermost level is the dial itself. It appears opaque but is in fact translucent, allowing light to pass through and power the solar movement. The photovoltaic cells are positioned beneath it. Finally, at the deepest level lies the heart of the FC-120 calibre. Its rechargeable battery stores solar energy converted into electricity. An integrated circuit manages the energy flow, acting like a switchyard: part is directed for immediate use, while the remainder is stored in the battery, enabling up to 10 months of autonomy without light.

Driven by its philosophy of innovation, Frederique Constant Manufacture continues to break down barriers in watchmaking. The Classics Moneta captivates with its refined aesthetic, meticulous finishing, and remarkable technology. Swiss Made watchmaking at its finest, delivering exceptional added value. The distinctive design of the Classics Moneta, with its fluted flange, has established itself as one of the brand’s most appreciated signatures. Its Solarmetre variation opens limitless solar horizons for collectors who value innovation.
