Light-powered watches manufactured by Citizen utilize a rechargeable power cell that stores energy converted from light sources. This power cell eliminates the need for periodic replacements, providing a sustainable and convenient timekeeping solution. For example, exposure to sunlight or artificial light replenishes the stored energy, ensuring continuous operation.
This technology offers significant advantages for both consumers and the environment. By eliminating the need for regular battery changes, it reduces waste and the demand for disposable batteries. This contributes to a lower environmental impact compared to traditional battery-powered watches. The long-lasting power reserve and reliable performance further enhance the user experience. This technology has evolved since its inception, improving efficiency and storage capacity over time, establishing Citizen as a leader in light-powered watchmaking.
