This is a Casio G-Shock GW7900B G-Rescue Atomic Watch Black. With the never ending pursuit of toughness and technology, G-Shock introduces a Solar Atomic addition to the tough and rugged G-Rescue series. Already iconic for its four point protection design, large case, oversized buttons, tide & moon graphs, this new model keeps the same design philosophy of allowing for high functionality and operability, in the harshest conditions, even while wearing gloves. 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.
