GSTB300-1A
From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, come new rugged style G-STEEL models that feature Carbon Core Guard structures.
Technology
Carbon Core Guard
A new Carbon Core Guard structure for GST-B300, which protects the module with a carbon case. Highly durable carbon fiber-reinforced resin is added not only to the center case, but also to the front and side button guards, providing even stronger resistance to shocks from above or below, or from any side.
Tough Solar
CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power.
Design
Bezel & Front Button
The battery indicator at the 6 o’clock position, designed to evoke a brake disk, shows the remaining battery power by an arrow pointer and a curved red bar, providing visually interesting ways to check the battery.
