The new GM2100 models inherit the octagon form that was employed for the original DW-5000C and now feature a steel bezel. Analog-digital timekeeping comes packed into a no-nonsense simple design without sacrificing G-SHOCK level toughness. High-strength resin material reinforced with carbon fibers makes it possible to create a case that is a mere 11.8mm thin, which is the thinnest among G-SHOCK combination models. Additional features include 200-meter water resistance, shock resistance, and double LED light. The resin strap secures with a buckle clasp.
