Casio G-Shock Carbon Core Guard Analog-Digital Red Resin Band Watch. This tough timepiece boasts a carbon core structure that protects the case by enclosing it in a carbon case while keeping it only 11.8 mm in thickness. The design pays homage to retro G-Shock styles with an octagonal bezel and traditionally shaped red resin band. The distinctive red color is also seen on the dial along with an analog-digital display and double LED light feature, for easy visibility in the dark.
