Tough Solar System

Solar watches are powered by light energy. The solar fields "catch" the light and transform it into energy. The CASIO Tough Solar System is now so advanced that even the weakest light sources are sufficient to operate the watches.

The solar cells are so small and inconspicuous that they can be integrated easily into every watch face design. CASIO's solar field can also be manufactured in any colour and design.

An accumulator in solar watches saves "superfluous" energy and releases it when the watch is in darkness. Solar watches are always equipped with an accumulator. The accumulator is charged automatically and does not require manual activation.
