CASIO G-SHOCK FROGMAN 30TH ANNIVERSARY GW-8230NT-4JR MADE IN JAPAN JDM

Dive deep into the celebration of the 30th anniversary of the G-SHOCK Master of G FROGMAN family of full-fledged diver’s watches with ISO-standard 200-meter water resistance.

The third commemorative model to mark the 30 years since the first FROGMAN made a splash in 1993, this limited-edition timepiece revisits the bold design of the DW-8200NT debut in 2000 — the iconic asymmetrical FROGMAN shape with striking red band, bezel, and LCD.

More than just a revival, the redesign evolves with a focus on reducing environmental footprint. Earth-friendly bio based resins are used in the bezel and band, and the Tough Solar feature is powered by a solar panel designed especially to complement the shape of the DW-8200 dial.

For this very special 30th anniversary design, the popular diving frog so familiar to FROGMAN fans is engraved on the case back and displayed with the LED backlight.
