Casio G-Shock GA2100

The bezel, band, and dial feature a monochromatic color scheme in white, light blue, or yellow. Each component, including index marks and inset dials, is painstakingly shaded and textured in a slightly different way to achieve a streamlined and solid watch face design.

The bezel and band are made with environmentally friendly bio-based resin, a polymer made from materials extracted from corn. Produced using chemical or biological synthesis of renewable organic resources, the material is expected to help reduce environmental impact and facilitate a shift to a circular economy.
