Solar Powered

A solar panel converts even weak illumination from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it's a solar battery.

Casio watches with solar technology, receive thermal and electrical energy that recharges the watch batteries through solar panels on the face of the watch.

Solar Power Features:

The combination of a solar panel with a large-capacity rechargeable battery enables a variety of energy-hungry functions to operate smoothly.

• Digital Watches: Digital display of various functions
