This SLEEK STYLE G-SHOCK pairs minimalist construction with a soft urethane band for light, comfortable everyday wear. Bezel details and a brick pattern recall the first DW-5000C. A metal bezel guards against impact while a carbon-fiber-reinforced resin case protects the module. Bonded glass and a compact module help reduce thickness and weight while retaining shock resistance. Its restrained design suits business, casual and outdoor use. Major resin components in the case and band use bio-based resin.
