Casio G-Shock GA-2100K-1AER

Immerse yourself in a mysterious, smoky light atmosphere with the Casio G-Shock GA-2100K-1AER watch. Inspired by the rhythmic nightlife of music, this model evokes the shadowy pulse of nightclubs and music festivals, where laser lights cut through the midnight beats.

A newly developed surface treatment gives the dial a clean and refined look that perfectly complements the iconic and streamlined GA-2100 “CasiOak” design. The smooth dial serves as the ideal base for the glossy surface and rich color scheme that reflects the impressive depth of the deep black. The varying textures and tones of the watch’s various parts evoke a late-night music scene – neon details shimmer like laser lights, and the translucent, matte bezel and strap create an atmosphere reminiscent of a dance floor filled with smoke machines.

This bold new look is combined with G-SHOCK’s legendary durability. Shock, vibration and 200m water resistance, along with Carbon Core Guard construction, ensure style never takes precedence over practicality.
