# CASIO G-Shock ANALOG-DIGITAL 2100 Series | GA2100HDS-7A

Take your inspiration from the summer seas, with the white and blue G-SHOCK.

The watch’s blue phosphorescent face glows magically at night, evoking the shimmer of bioluminescent plankton floating in the sea. Paired with a white and blue color scheme, the design beautifully captures the beach’s dynamic transformation from the brilliance of the daylight sun to soft nighttime hues.

Shimmery sea-inspired styles flow easily from casual settings to work situations.
