G-STEEL daring meets sophisticated gleam in monochromatic silver color scheme. The monochrome aesthetic pairs a metal bezel colored silver with a newly developed tough silicone band in the same color. The surface of the band is protected with a urethane sheet finished with vapor deposition in silver to achieve a metallic glimmer in a band that feels great against the skin. Soft and comfortable to wear, with a glittery metal look, these timepieces are fashion items that take you wherever you want to go. Choose your favorite — the iconic GM-2100 with octagonal bezel.
