G-Shock DW6900WS-1 Watch in black
G-Shock's Smokey Sea Face Series expresses the multi-faceted moods and looks of the majestic seas. This lineup’s colors are based on a summer sea motif, which changes its appearance depending on the time of day, including the jet-black of the night sea. The bezel and band are decorated with a pattern that resembles an ocean wave, which is made possible by mixed-color resin molding technology.
