Product Information
Overview
The Casio G-Shock GA-B2100-3AER is a durable anadigi watch featuring G-Shock's iconic "2100" silhouette and a distinctive green color scheme. It combines analog clarity with digital functionality in a sporty format that feels modern and practical. With shock-resistant construction and 20 ATM water resistance, it's built for an active life, while the black dial gives a sharp, technical expression.
Comfort
Its lightweight design and resin/rubber materials ensure the watch sits securely without feeling heavy, even during exercise and movement. The relatively slim profile for a G-Shock allows it to wear smoothly on the wrist, and the buckle makes it easy to adjust the fit. Double LED illumination improves readability in the dark, and the hands can be moved aside to provide an unobstructed view of the digital display.
