Upgrade the retro look you love with the octagonal Casio G-Shock GA-2100 line, which inherits the design concept of the very first G-Shock, but now with Smartphone Link and Tough Solar power. Bold in design, this model features a green carbon fiber-reinforced interior case and matching green resin band. The dual-layer dial construction highlights the dimensionality of the LCD and inset dial and meticulous attention to detail gives the dial a look of enhanced texture.
