Casio G-ShockGA-2100-1A3ER Black

The GA-2100 inherited the octagon form from the original DW-5000C. Its case and bracelet are crafted from a high-strength resin material that is reinforced with carbon fiber, yet the case remains the thinnest among G-Shock combination models, measuring a mere 11.8 mm (.5 in) thick. Also known for its technical specifications, G-Shock has outfitted the GA-2100 with a background illuminator and neo-display for visibility in low-light situations, timer and stop function for athletes, multifunctional alarm, world time function with up to 29 different time zones, and automatic calendar, among other features. G-Shock was born out of a need for a timepiece that wouldn’t break even when dropped.
