G-Shock GRB200-1A9 Watch
G-Shock GRB200-1A9 Watch – Gravitymaster (Master Of G – Air)
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.
