Casio is celebrating the 30th anniversary of the G-Shock Frogman, a big fat amphibious watch that’s not for the small of wrist. The new GWFA1000APF1A’s radical colorway and patterns come straight from the South American Poison Dart Frog. Black, blue, and orange carbon and glass fibers are woven together and then laminated. Every piece has an original pattern thanks to the random weave, and translucent case guards provide depth and protection. The markers and hands also match the multi-colored bezel. For an even more unique look, the strap is sprayed with a polarized paint that changes colors in different lighting situations. The caseback gets its own Frogman engraving. The watch offers 200 meters of water resistance, solar-powered quartz timekeeping, and smartphone syncing. It’s also a limited edition model, so expect them to sell out quickly.
