G-Shock GA-2100-5AER Watch - Carbon Core

(15,786 reviews)

The GA-2100 had HUGE success last year, and so Casio has dropped the iconic G-Shock design in fresh shades for 2021. Building on the famous octagonal shape, it features a chic black face with bold hour and minutes hands powered by reliable quartz movement, while the shock resistant structure protects against impact and vibration. This bold design comes together with a stylish taupe resin strap for effortless wear come day or night. Still water resistant up to 200m and with a stopwatch, world time and alarm functions - it’s geared-up for adventure.
