Practicality and smart style—all with G-SHOCK's functionality and toughness. The black face is paired with a beige or olive green strap, and the versatile two-tone color is reminiscent of the practical appearance of an outstanding piece of kit. There are five basic models to choose from: the DW-6900 with its iconic triple graphic or the GA-700 with its large case design, both of which feature metal front buttons with a non-slip finish; or the GX-56, GA-100 and GA-110 in large case styles.
