Aircraft cockpit-inspired aesthetics
The G-Shock Gravitymaster GR-B300 series is a modern take on a pilot’s watch that combines G-Shock's signature ruggedness with a design that takes cues from an aircraft’s cockpit. Like earlier Gravitymaster watches, the GR-B300-8A2 utilizes the Carbon Core Guard structure, which Casio claims is made of the same carbon material used in aircraft fuselages. The triple-layer 3D dial and oversized bezel add depth to the watch face and improve readability, while the large, blue accented indices and hands echo a pilot’s head-up display (HUD).
You get dual-time support for tracking two time zones at once, and a flight log feature that lets you record flight data like times, points of departure, transit points, home destinations, and so on. Bluetooth connectivity is also onboard, allowing you to link the watch to your smartphone using the Casio app while also enabling automatic adjustments four times a day for impeccable accuracy.
The GR-B300-8A2 comes with Tough Solar charging, so you won’t have to worry about frequently replacing the battery—even when stored in total darkness, Casio says the watch lasts up to 18 months.
