Carbon core guard structure realizes thinness and light weight

The case is made of fine resin containing carbon fiber, and the "carbon core guard structure" provides both high impact resistance and light weight. With a thickness of only 11.8mm and a weight of approximately 51g, it is incredibly slim and light to wear, making it hard to believe that it is a G-SHOCK. It is designed to be comfortable not only for outdoor activities and sports, but also for everyday use, with less stress even when worn for long periods of time.
