These Tough Solar models provide a choice of either the original G-5600 G-SHOCK design or the G-6900 design that is so popular among followers of today's street fashions. 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.
