Casio G-Shock Watch GA-2000-1A9

From G-SHOCK, the toughness watches that continue to evolve in search of ultimate strength, this model uses a carbon core guard structure. The case is made of fine resin containing carbon fiber that, although lightweight, exceeds the rigidity of normal resin. Prevents damage and deformation from impacts to protect the internal module.

The two-layer structure of the back cover guards against impacts to the back of the watch. The shock-proof button structure also allows the exterior to be designed without a button guard.
