These G-SHOCK Master of G “GRAVITYMASTER” GR-B200 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 helicopter control stick, while also contributing to ease of operation.
