Go sleek, sharp and bold with a G-SHOCK standard-bearer in a metal-clad octagonal take on the original iconic design.
Forged in stainless steel with rounded hairline finish, the strong bezel says super style all the way. The dial is treated with vapor deposition finish for a meticulously detailed metallic look that suits a classic metal G-SHOCK timepiece. Incremental variations in the detailed square dot texturing on the wristband take casual urethane materials up a notch.
