Since its launch in 1983, G-SHOCK has remained at the forefront of innovation, constantly redefining toughness. That legacy continues with the new HIDDEN GLOW series—featuring glow-in-the-dark elements that represent the hidden, untapped potential within us all.

Inspired by the serene beauty of summer seas, these models showcase a refreshing white and blue colour palette. Their luminescent dials capture the captivating glow of bioluminescent plankton, evoking the magical transition from daylight to twilight on the beach. Each timepiece features a distinct dial design, using light and colour to express its unique character.

The GA2100HDS-7A stands out with a bezel and band crafted from bio-based resin—an environmentally conscious material that reflects G-SHOCK’s commitment to reducing environmental impact.

Striking and versatile, the HIDDEN GLOW series adds a bold, contemporary touch to everything from casual outfits to office-ready looks.
