LIMITED EDITION
GRB200RAF-8A

GRB200RAF Gravity Master

Designed in conjunction with the Royal Air Force, the watch has been built to accommodate the severe environments faced by pilots using a carbon core guard structure. This, combined with world-renowned G-SHOCK shock resistance, creates a structure that is highly vibration resistant. The bezel is made up of three layers of resin with carbon fiber inserts, with the top layer being semi-transparent to reveal the carbon material inside.

The special edition timepiece features design elements inspired by aviation, including the three buttons on the right side of the watch arranged in a way that makes them resemble a helicopter control stick while also contributing to ease of operation. Additionally, the stealth colorway is inspired by the Eurofighter Typhoon, designed to be difficult to distinguish in the sky during operations.

GRB200RAF-8A

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.
