Casio GMA-P2100BB-1A

A modern, all-black G-SHOCK that can be worn in the city or in the wilderness. Its monochrome design with a matte finish is as simple as it is bold. The main components of the bezel/case and strap are made from bio-based resin, a material chosen because it helps reduce environmental impact.
