From G-SHOCK come new G-STEEL model designs with "layer guard structure" for outstanding shock resistance. New "tough leather" combines resin with synthetic leather for a band that is water resistant, and has better wear resistance and tensile strength than leather materials of the past. Distinctive stitching adds an authentic leather look. The multi-dimensional face features large hour markers and hands that have an ivory texture. A combination of antique and modern, the subdued design of this watch recalls a vintage motorcycle or rider jacket.
The GST-S120L comes in a choice of two models, one black and one rose gold. Black and mustard, and rose gold and black combinations create designs that are elegant and powerful.
In addition to Tough Solar and a hand shift feature, these models feature Neon Illuminator for the face and a white backlight for the digital display provide easy reading even in the dark.
