Product description

The Frogman GW-8230NT-4ER is already the third commemorative model to mark the 30th anniversary of the G-SHOCK Master of G FROGMAN family. This limited-edition is based on the design of the first DW-8200NT from the year 2000; the asymmetrical shape with striking red band and bezel. The redesign focusses on reducing its environmental footprint by using bio-based resins and the watch is powered by a solar panel designed especially to complement the shape of the dial. The iconic Frogman diving frog character is engraved on the case back and also makes an appearance on the LCD display each time the backlight button is pressed.
