Master of G-Air Gravitymaster 54.7mm Black Dial

Gold-toned detail meets bio-based carbon on the Casio G-Shock Master of G-Air Gravitymaster, reference GRB300H-5A. The 54.7 mm case uses a carbon core guard structure and light yellow gold ion-plated stainless, and the black dial is read with Neobrite luminous markings and a day and date display. The case is 15.7 mm thick.

Tough Solar power runs the quartz movement, with a battery level indicator, and a Bluetooth smartphone link supports a flight log via the app. Dual time, a stopwatch, a countdown timer, a daily alarm, an LED Super Illuminator and a full auto-calendar are included. Mineral glass covers the dial, a stainless steel screw back closes the case and water resistance is 20 bar (200 m). The resin band uses a tang buckle, for pilots and travelers who want a large, rugged watch.
