Casio's Gravitymaster "Master Of G-Air" GR-B300 series is heavily discounted for a limited time. You can pick up either the GR-B300-1A4 with orange accents evoking a night cockpit vibe or the blue/gray GR-B300-1A4 inspired by a pilot’s head-up display (HUD) for just $180.

If you’ve been eyeing Casio’s aviation-inspired Gravitymaster series, now’s a great time to pull the trigger. The G-Shock Gravitymaster GRB300-1A4 pilot watch is currently available for just $180 at Casio.com, a 40% discount off its usual retail price of $300.

The GRB300-1A4 is designed to capture the mood of a night cockpit, and Casio really commits to the bit. The watch pairs a matte black body with bright orange accents inspired by low-glow instrument lighting aboard an aircraft. Up close, the triple-layered dial and 3D indices give the face a surprising amount of depth, while the oversized hands and Super Illuminator LED make quick readability a non-issue in dim cabins or dark streets.

If you’d rather lean into a more tech-forward cockpit aesthetic, the Gravitymaster GR-B300-8A2 is also on sale for $180 (40% off). This one swaps the orange glow for a gray-and-digital-blue, HUD-inspired design while still retaining bold, still aviation-centric, and easily one of the most futuristic-looking variants in the series.

Except for the color scheme, both watches share the same build and features. The bezel flows in a single smooth contour—Casio says it’s modeled after next-generation aircraft—and the entire case uses carbon fiber–reinforced resin to keep things light without compromising strength. Both have the usual G-Shock credentials, including 200-meter water resistance, shock protection, and the Carbon Core Guard structure.

The GRB300-1A4 and GRB300-8A2 also bring a handful of smart touches. Bluetooth syncing with the Casio app automatically updates the time four times throughout the day (no matter where you land), while dual-time tracking lets you keep tabs on both your departure and destination zones. You also get the usual time-keeping features, such as world time, alarms, a stopwatch, a rotary status indicator, and a full auto-calendar round out the feature set.
