Casio G-Shock Master of G FROGMAN Limited Edition GW-8200TPF-1

Frogman embodies a bright, bold, and fearless spirit, reinterpreting the powerful aesthetic of the three-striped poison dart frog from South American rainforests for G-SHOCK. The fluorescent green and black design recalls the animal's warning coloration, with bold vertical stripes popping up against a dark base for a striking and unmistakably rugged look. The strap and bezel feature a spray-on finish that evokes the natural texture of the frog's skin, while the caseback features the iconic diving frog symbol that is distinctive to the Frogman collection. Using Tough Solar technology, the watch is charged by light, eliminating the need to change the battery and ensuring reliable performance even in low-light conditions, while the bio-based resin bezel and strap underscore the model's focus on functionality and sustainability without sacrificing the extreme durability typical of G-SHOCK.
