- Introducing new special collaboration models between G-SHOCK, the watch that has been revolutionising timekeeping toughness since 1983, and the world-famous virtual band Gorillaz. Base models for this lineup are the world-popular square design digital 5600 Series. The colors of the GWB5600GZ model are inspired by the hues of Gorillaz's latest* album "NOW NOW." A combination of pop blue and pink are incorporated into the design, and the bi-color message "NOW" floats onto the display whenever it is illuminated with the backlight.
