A smaller G-STEEL model that expands the range of design variations by making the module smaller while retaining the same layer guard structure and features. Uses a black urethane band on a GST-W310 base model equipped with advanced features. The stainless steel bezel gives the model an edge, and the black finish on the dial and the band creates a monotone design. Used a light-shielded distributed solar cell to enhance the beauty of the dial.
