It features Tough Solar charging, Bluetooth® Smartphone Link, Carbon Core Guard construction, Flight Log recording, Dual Time, and 200-meter water resistance.

Casio G-SHOCK GRAVITYMASTER Bluetooth Solar Men Watch - Black | GR-B300-1ADR belongs to the MASTER OF G – AIR collection and is designed as aviation-inspired professional gear for demanding environments. Its seamless black exterior, dimensional indexes, and large-diameter triple-layer dial provide strong visibility and a rugged technical appearance.

The watch uses a Carbon Core Guard structure that combines lightweight carbon-fiber-reinforced resin with excellent shock resistance, rigidity, and corrosion resistance. Bio-based resin is used in key case and band components, while the contoured exterior provides a secure and comfortable fit.

Tough Solar technology converts natural and artificial light into power. Bluetooth® Smartphone Link connects the watch to the CASIO WATCHES app for automatic time adjustment, easy settings, access to approximately 300 world-time cities, Flight Log recording, and Phone Finder. Dual Time displays the time in two cities simultaneously and allows quick swapping between home and local time.
