This is a Quad Sensor-equipped model in the G-Shock Gravitymaster Series, designed for pilots working in harsh conditions. Its structure combines a carbon fiber-reinforced resin case with a Carbon Core Guard that protects the module, offering shock resistance and fortifying the watch against vibrations. The resin that forms the bezel area has a three-layer Carbon Fiber Insert structure, making it wear-resistant. The three buttons at 3 o'clock have been designed to resemble a helicopter control stick, while also achieving ease of use. An iconic orange has been used on the dial and band to symbolize the strength and spirit of air rescue teams. Function-wise, this model comes equipped with a Quad Sensor featuring compass, altimeter/barometer, temperature reader and pedometer. It also offers time correction by linking to the dedicated G-Shock app, and the Mission Log feature allows the various data obtained by the watch to be recorded in the app. You can also use the app to set modes on/off and customize settings, including switching between displays. This is a Gravitymaster model that embodies the mobility of a helicopter along with all the functions and toughness essential for flight missions.
