G Shock Duo Sea of Star Glow GA2100HDS-7A White/Resin

Take your inspiration from the summer seas with this white and blue G-SHOCK, designed to capture the glow of ocean nights. The phosphorescent blue face lights up after dark, echoing the shimmer of bioluminescent plankton drifting across calm water. Paired with a clean white and blue palette, it transitions effortlessly from bright daytime to soft evening hues.

Lightweight, shock-resistant and built with a Carbon Core Guard structure, this style is as ready for daily wear as it is for the outdoors. A polished, sea-inspired look that moves easily from casual settings to work.
