With the never ending pursuit of toughness and technology, G-Shock introduces a Solar Atomic addition to the tough and rugged G-Rescue series.

With its monotone, grey IP coloring and aperture band design, this new addition to the G-Rescue series not only looks tough, it also very comfortable to wear.
