Casio G-Shock GA-2100HD-8A

Unlock your full potential, and bring what’s hidden to the fore. Introducing the G-SHOCK that glows in the dark.

This line features luminescent parts set against a dark gray base — a design inspired by the hidden talents we each have, but rarely reveal.

We start with a base of gray to evoke the dark, then add luminescent components and white accents to the face, creating a monochromatic watch with an extra special glow.

Search out a dark space and watch this cool design come to life in glowing luminescence.
