This special model commemorates the 30th anniversary of the birth of G-SHOCK MASTER OF G's authentic diver's watch "FROGMAN". The bezel is made of multi-colored carbon to express the mysterious colors of the rare hermit frogs that inhabit the Amazon in South America. Combined with a skeleton urethane material, it also expresses the texture of the skin of hermit frogs that inhabit the waterside. The band is spray-painted with polarizing ink to resemble the speckled pattern of frogs. Furthermore, the engraving of the frog character on the back of the case, an indispensable part of the FROGMAN series, is also finished to a special specification with a speckled pattern of hermit frogs.
