The 45mm g-shock ga2100 features a virtual reality-inspired look. These 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. Featuring 200 meter water resistance, shock resistance, and a double led light, the watch secures with a buckle clasp.
