Casio G-SHOCK GA-700 Series – Model GA700HDS-7A
The GA700HDS-7A draws inspiration from the summer seas, blending crisp white with shimmering blue for a refreshing, ocean-inspired look. Featuring a phosphorescent face that glows in the dark like bioluminescent plankton, this watch captures the magic of the sea both day and night while maintaining G-SHOCK’s legendary toughness.
Design Overview
This model’s dial incorporates resin components imbued with phosphorescent material, creating a gentle blue glow in darkness. The unique color play recalls the beach’s transformation—from the brilliance of the midday sun to the calm hues of the night sea. Combined with the oversized GA-700 case, the striking white-and-blue design transitions seamlessly from casual wear to work settings.
With its signature front button, shock-resistant build, and 200-meter water resistance, the GA700HDS-7A is engineered for both style and performance. The Super Illuminator LED light ensures excellent readability in the dark, while the multifunction features keep you ready for any situation.
