Introducing the G-SHOCK as nature-minded as you, made with renewable materials and a focus on sustainability. This not only helps manage environmental impact, but also ensures workers are protected and craftsmanship is high quality throughout the production process.The bands are colored with dyes from FOOD TEXTILE, a project to reuse food that would otherwise be discarded to create natural dyes. Soft, earthy colors are brought to life with dyes made with over 90% natural ingredients.The dark brown hue of the GA-B2100CT-1A5 band is achieved with a dye extracted from coffee, while the khaki grey color of the GA-B2100CT-5A band comes from a dye extracted from echinacea. Materials that had been destined for the trash are reborn in a beautiful new form β€” a sustainable, environmentally friendly watch.
