Tough Solar
Solar Powered
Casio's proprietary solar charging system converts not only sunlight, but even light from weak light sources such as fluorescent lamps, into power.
Stable operation of high-load functions
A solar panel that generates power from even a weak light source combines with a large-capacity rechargeable battery to drive multiple power-hungry functions reliably. The area required for the LCD, dial printing and other elements is calculated precisely to permit installation of a highly resilient film-like solar panel on the dial. Six solar cells connected in a series all receive the same amount of light.
