With the never ending pursuit of toughness and technology, G-Shock introduces the GW7900B-1 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.
