This Limited Edition G-SHOCK GST-B300 men's watch comes as a set with three bands- stainless steel, brown cloth, and black polyurethane. This series 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 men's watch features automatic time adjustment via Bluetooth when paired with a dedicated smartphone app, world time setting for over 300 cities, as well as various alarm and countdown timer settings. It is also equipped with other practical functions such as the solar charging system developed by Casio, and a high-luminosity full auto double LED light.
