EDIFICE Solar watches are powered by light energy. The solar fields “catch” the light and transform it into energy. The CASIO Tough Solar System is 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 color and design.
An accumulator in EDIFICE solar watches saves “superfluous” energy and releases it when the watch is in darkness. EDIFICE Solar watches are always equipped with an accumulator. The accumulator is charged automatically and does not require manual activation.
EDIFICE Solar PROs & CONs
| PROs | CONs |
| almost lifetime power for your watch (long-lasting battery) | can “sleep” and never awake after a long time in the darkness |
| easy to charge (requires almost any source of light) | still requires charging (though it doesn’t require any manual maintenance) |
| eco-friendly (rechargeable battery) | more expensive battery type |
| continues working up to 6 months even when left in complete darkness (sleep mode) | rechargeable battery still requires a change after some time (in 10 years for long-lasting movement performance) |
| probably the most reliable watches in the world | too expensive (in comparison with non-solar) |
