Watch CASIO G-SHOCK G-Steel GST-B200B-1AER

Carbon Core Guard structure
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. The small case of the GST-B100 series base model provides a comfortable fit, even though the watch is equipped with a wide face.
The light-on-dark LCD contributes to both functionality and face design.
