This MASTER OF G Series FROGMAN GWFA1000 Series analog watch with ISO 200m diver-level water resistance features the coloring of the Borneo rainbow toad, a rare toad that inhabits Borneo that was rediscovered in 2011, for the first time in about 87 years.

The stainless steel bezel is etched to create depressions and is finished with rainbow ion plating (IP) to create the look and feel of a Borneo rainbow toad. The rainbow IP creates different and unique coloring for each model, which represents the rarity for the rainbow toad.

In combination with the semitransparent urethane of the parts gripping the bezel, this captures the image of the pristine habitat of the rainbow toad. The image of a frog holding an analog hand is engraved on the back cover of this model.
