The GRAVITYMASTER G-Shock series was conceived and developed as aviation timepieces with pilot-friendly functions. A large button located at 9 o’clock can be used to trigger a 60-second continuous bearing or temperature sensor reading with a single press. High-luminosity LED display light enables reading of display information even in the dark, and in addition to displaying the time in your current location, a second time can be indicated by the 9 o’clock dial. All of this and a new World Time function, designed with international pilots in mind, makes GRAVITYMASTER the logical watch of choice for adventure seekers.
