Street-smart and nature-minded � a fashionable G-SHOCK dressed in all black. The monochromatic design with a matte finish makes for a simple, yet bold design. Key resin components of the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact. Choose your favorite all-black timepiece � the GMD-S5600, a smaller, slimmer version of the iconic G-SHOCK design, or the ever-popular GMA-P2100 analog-digital combination.
