Tough Solar

Tough Solar is the name given by Casio to the solar powered battery charging system used in its G-Shock, ProTrek, Pathfinder and other lines of watches.

A self-contained, environmentally-friendly solar cell provides a supply of energy to the watch. Spare solar energy is saved in a battery.

Normally, the solar cell and rechargeable battery should be able to last as long as the watch.
