The g-shock gm2100 models inherit the octagon form that was employed for the original dw-5000c. 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. 8 mm thin, which is the thinnest among g-shock combination models. The watch features a 43mm gold-tone stainless steel case, 200 meter water resistance, shock resistance, a double led light and a resin strap that secures with a buckle clasp.
