These Quad Sensor Bluetooth connected G-SHOCK Master of G “GRAVITYMASTER” GRB200 models pack flight mission essential functions into a tough and rugged carbon core guard structure.

A high-strength, highly weather-resistant Carbon Core Guard Structure protects the module with a resin case reinforced with carbon fibers. This, combined with world-renowned G-SHOCK 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 Quad Sensor system of these models 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 simplifies configuration of watch settings, and also provides a Mission Function.
