Casio G-Shock Digital Solar Powered G5600UE-1

This tough solar model is the original G-5600 G-SHOCK design.
The Tough Solar system, which is equipped without changing the basic design of the watches, makes it possible to generate enough power to keep the watch running with minimal exposure to normal lighting.
