From G-SHOCK, the watch that sets the standard for timekeeping toughness, comes the latest models to feature a stealth GX56BB-1 black that captures the essence of one-tone resin. These models are based on the AW-591, DW-6900, GX-56 and G-100, which are designed to withstand impact from any direction, and the compact and practical AW-591 design. A simple matte black finish allows the form of the watch itself to stand out, while the buckle, buttons and bezel* have a black ion plate finish. Everything about these new stealth black models captures the very essence of the rough, tough basic G-SHOCK image.
