G-SHOCK GA-2100K-5ADR Octagonal Bezel

Immerse yourself in the feel of mysterious, smoky light with a watch inspired by the music-driven nightlife. 

These new watches bring to life the shadowy thrill of nightclubs and music festivals, laser strobes cutting through the beat of midnight music. 

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 color scheme, which projects the incredible depth of piano black.

The varying textures and colors of the watch components recall the late-night music scene. Accents in neon colors 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.

A whole new look and feel — cutting-edge design infused with G-SHOCK shock resistance.
