G-SHOCK GA-2100K

Clean, modern dial design

A newly developed surface finish imparts a clean look to the dial that perfectly complements the streamlined design of GA-2100 watches. This smooth surface is the ideal canvas for the glossy finish and rich colour scheme, which projects the incredible depth of piano black.

Ethereal nightlife, rendered in layered textures and vibrant hues

The varying textures and colours of the watch components recall the late-night music scene. Accents in neon colours sparkle like laser light, while translucent materials with a matte finish are employed to give the bezel and band a fantastic texture reminiscent of the dance floor haze created by a fog machine.
