Overview
Introducing the Multi Fluorescent Color series from G-SHOCK, the modern timepiece that has continued to evolve to meet the needs of unmatched toughness since its launch in 1983. The matte black bezels and bands are offset by vivid fluorescent blue, pink, and yellow colors inspired by the virtual world for the hour and minute hands, hour markers,and dial markings. Base models are the Bluetooth® Solar GA-B2100 with octagon bezel, the big-case GA-100, GA-110, and GA-700, and the digital big-case solar GX-56. The cool matte black coloring and vivid accents create designs that look great whenever and wherever these watches are worn.
