GA2100HD-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 grey base — a design inspired by the hidden talents we each have, but rarely reveal.
We start with a base of grey 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.
