From G-SHOCK, the watch lineup that has constantly been testing new limits in timekeeping toughness since 1983, comes a new all-black metal and resin G-STEEL model. The metal bezel has a black ion-plated (IP) finish, creating a chic and fashionable look. The base model is the GST-B400, which features a thin module and carbon core guard construction. The G-STEEL series delivers in terms of both toughness and design, and the cool all-black coloring creates a universally fashionable look.
