G-SHOCK GA-100TU-1A3DR

Utilitarian practicality, savvy style — all with G-SHOCK functionality and toughness.

Pairing a black watch face with a band in beige or olive green, the two-tone utility color line evokes the functional look of a great piece of kit.

Choose from five base models: the DW-6900 with iconic triple graph or the GA-700 with large case, both of which feature a metal front button with anti-slip finish; or the large-case designs of the GX-56, GA-100, and GA-110.
