A third FROGMAN 30th anniversary commemorative model

This diver’s watch is the third commemorative model for the 30th anniversary of the FROGMAN, a line of diver’s watches known for the ceaseless pursuit of uniqueness and change since the first model made a splash in 1993. The new watch revisits the design of the DW-8200NT that debuted in 2000, using state-of-the-art technologies. Tough Solar charging, the use of bio-based resins, and other features all help to reduce environmental impact.

 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.
