G-Shock is fortifying its G-Steel series with two new Tough Solar models with Multi-Band 6 timekeeping. Both have basic black coloring featuring a black IP on the bezel and case, along with Neo-Brite luminous white hands and double LED lights. The GST-W100G-1BJF has a resin band, while its counterpart GST-W110BD-1BJF carries a more rugged aesthetic, courtesy of a metal band with black IP. For now, the watches are available exclusively in Japan. We’ll have to wait and see whether the pieces make their way to our shores.
