G-Shock's signature toughness in the rugged Master of G collection takes to the skies with an all-new Quad Sensor-equipped Gravitymaster pilot's watch. 

The Quad Sensor Gravitymaster is built around G-Shock's high-strength, highly weather-resistant Carbon Core Guard Structure, which protects the module with a resin case reinforced with carbon fibers. This, combined with world-renowned shock resistance, creates a structure that is also highly vibration resistant. The bezel is made up of three layers of resin with carbon fiber inserts. The top layer is semi-transparent to reveal the carbon material inside. The three buttons on the right side of the watch are arranged in a way that makes them resemble a fighter jet control stick, while also contributing to ease of operation.

The Gravitymaster's Quad Sensor system uses compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurement capabilities, along with an accelerometer that keeps track of your step count, into a compact configuration. This makes it easy to keep tabs on the natural environment around you and to maintain logs of your activities for comprehensive flight mission support. A special G-Shock phone app enables the wearer to easily configure watch settings, and also provides a unique Mission Function.
