GA2100HD-8A

ARCHIVE MODEL

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.

Reveal the Hidden Glow – G-SHOCK Glow-in-the-Dark Collection

Commanding style in the dark is often difficult but not for the Hidden Glow collection of G-SHOCK watches. The matte gray of the GA700HD-8A, the GA2100HD-8A, and the DW6900HD-8 fades out of sight in the dark to underscore the luminescent glow-in-the-dark components of the dial. For top performance in the dark, all three watches have an iteration of our Super Illuminator LED light, providing a further boost for readability.

Express what’s hidden. The Hidden Glow collection by G-SHOCK.

Glowing faces express personality
with colour and light

Matte grey bezels and bands meet white faces and black inverted LED displays in a monochromatic worldview built with neutral shades. All or part of each dial incorporates resin parts imbued with phosphorescent material, providing a green glow in darkness that reveals each model’s distinctive face design in silhouette.

Attention to materials: Bio-based resin

Key resin components used in the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
