G-SHOCK GRAVITYMASTER has long been the timepiece series at the forefront of tough timekeeping. Five side buttons and a front light button help to simplify operation by providing more direct access to functions. These models are the first of the G-SHOCK lineup to feature a large 7 x 33-dot LCD, and an ion plated multi-faceted metal bezel, creating the image of a state of-the-art aircraft. A bi-color molded band adds a definite touch of fashionable elegance.

Connected Engine supports time correction using a time calibration signal and Bluetooth®connection. After connection with a smartphone with Bluetooth® , you can use the G-SHOCK Connected* app to configure countdown alarm settings, to manage waypoint memory contents, and to manage and store a flight log of distances and travel times of flight missions. To ensure timekeeping accuracy, time information can be obtained from an on-line time server and used to correct the watch’s time setting.
