The ga2100 models from g-shock inherit the octagon form what 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 only 11. 8 mm thin, which is the thinnest among g-shock combination models. The 49mm watch features 200-meter water resistance, shock resistance, and a double led light.
