The new GA2100HC-2A color model was designed under the theme of exploration of an unknown coastal region. This new model is based on the thin octagonal GA-2100. The GA2100HC-2A uses a transparent clear resin to cover the watch case and highly transparent blue resin for the band. The HIDDEN COAST Theme Series is designed to go well with street fashions and other styles.
