The GA-2100HDS-7AER fuses the iconic design of the GA-2100 with a pearl white finish and deep blue accents that evoke the freshness of the sea in summer.
Its clean, modern aesthetic is enhanced by a glowing dial that recalls the glow of bioluminescent plankton on summer nights, conveying a sense of calm and movement, like the sky and ocean merging at sunset.
Crafted with renowned G-SHOCK strength, this ultra-lightweight model with Carbon Core Guard construction offers durability without compromising on style. Perfect for those looking for a versatile watch that flows between casual, urban and professional.
