Casio G-Shock Radio Controlled Watch

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new G-STEEL models that boast a new shock resistant Carbon Core Guard structure.
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.
