The new shock resistant structure of these models is the result of the G-SHOCK MT-G constant pursuit of improved strength and durability. A New Core Guard structure integrates the lugs and pipes that connect the band into single pieces, creating a wall that isolates the watch's module from impact. The resin of the center case is also reinforced with carbon fibers, which further enhances module protection, while reducing overall weight.
These watches come with a new Connected Engine module for improved timekeeping accuracy. A Bluetooth® communication function makes it possible to connect with a smartphone running the G-SHOCK Connected* app and obtain accurate time information from an on-line time server. MULTIBAND 6 automatically adjusts time settings based on reception of one of six time calibration signals around the globe, for automatic time adjustment when you are within the range of a signal, even if connection with a smartphone is not possible for some reason. All of this means that timekeeping is accurate, no matter where in the world you happen to be.
Other features include high-brightness LED illumination, World Time, stopwatch, and more. Stable operation is ensured by a CASIO original Tough Solar charging system.
