From G-SHOCK, the tough watches that continue to evolve in search of maximum resistance, a model that uses a carbon core protective structure. The case is made of fine resin containing carbon fiber which, although lightweight, exceeds the rigidity of regular resin. Prevents damage and deformation from impacts to protect the internal module. In addition, the two-layer back coating structure also protects against impacts on the back of the watch. The shockproof structure also allows the exterior to be designed without button protection. The design features a three-dimensional dial and a bold layout of large face buttons. Finished with a solid design that creates a powerful look. A model that combines the G-SHOCK shockproof structure with an urban outdoor style.
