Casio G-Shock GBX-H5600KI-5

Description

The G-Shock GBX-H5600KI-5 signature timepiece was developed in collaboration with pro surfer Kanoa Igarashi. It features a two-tone bio-based resin bezel and band with ocean-inspired lavender accents applied via vapor deposition on the dial. The watch includes a tide graph, optical heart rate sensor for training analysis, and a high-contrast MIP LCD for clear visibility in sunlight or underwater. A carbon fiber-reinforced resin case back reduces weight for enhanced comfort during surfing, running, and other activities, while Igarashi's signature and surfer number 50 appear throughout the design.
