G-Shock GSTB300S-1A G-Steel Connected Silver Black Men's Watch
The G-SHOCK GST-B300 with front button design, has been developed with a new Carbon Core Guard structure, 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. 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. As for functions, in addition to automatic time adjustment via Bluetooth when paired with a dedicated smartphone app, the watch features world time setting for over 300 cities as well as various alarm and countdowin timer settings, all easy to use. It is also equipped with other practical functions such as the Tough Solar, solar charging system developed by Casio, and a high-luminosity full auto double LED light.
