From G-SHOCK, the watch that is constantly testing new limits in timekeeping toughness, comes a new Utility Color addition to the GA2000. Built with Carbon Core Guard structure, which takes toughness to a new level. The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin. This material protects the internal module from shock-induced damage and deformation. The dual back cover protects the back surface against impact.
