Casio G-Shock Classic Octagon Series Chronograph Dual Display Black Plastic Strap Watch GA-2100-1AER

Built for everyday wear with a technical edge, the Casio G-Shock Classic Octagon Series GA-2100-1AER watch pairs a carbon-reinforced resin case with a resin strap secured by a buckle clasp. A black dial combines luminescent hands with LCD digital displays, protected by mineral crystal for a clean, durable finish.

Powered by a quartz movement with an accuracy of +/- 15 seconds per month, it brings practical functionality to the wrist. Shock-resistant construction supports impact and vibration resistance, while a 200 metre water resistance adds confidence for active use. Features include world time, a stopwatch, five daily alarms, an LED light and a hand moving function for clear visibility of the digital display.
