Features

From G-SHOCK, the watch that sets the standard for timekeeping toughness, comes the latest models to feature basic G-SHOCK black that captures the essence of one-tone resin. This model is based on the compact and practical AW-591 design. A simple matte black finish allows the form of the watch itself to come out, while the buckle, buttons, and bezel have a black ion plate finish.
Everything about this new basic black model captures the very essence of the rough, tough basic G-SHOCK image.
