G-Shock is a brand of watches manufactured by Casio, known for its resistance to shocks (e.g. hard knocks and strong vibrations). They were, and continue to be, designed primarily for sports, military, and outdoor adventure oriented activity; for example, practically all G-Shocks have some kind of stopwatch feature, countdown timer, light and water resistance. Recent models have become more luxury and design oriented as well as becoming very popular among youth.
