From GRAVITYMASTER, the tough watch designed for the severe environments faced by pilots, comes a new timepiece that delivers an even higher level of toughness through the use of the same carbon and titanium materials found on modern aircraft. A new shock resistant Carbon Core Guard structure integrates the case and back cover into a single carbon Monocoque unit that protects the module from external shock and makes it possible to eliminate carbon guard parts from the buttons on the sides of the case. The use of carbon material for the bezel and band, and titanium alloy for buttons, button pipes, and components results in a watch that is both structurally tough, lightweight, and resistant to rust. Automatic time adjustment is performed using either Bluetooth or a time signal, which helps to ensure accurate timekeeping while flying on a mission. Materials, structure, and functions. Everything about this model contributes to the creation of a new GRAVITYMASTER model with a new level of toughness that can stand up to new challenges.
