Casio releases the G-SHOCK GBX-H5600KI-5 signature watch in Malaysia on Aug. 6, 2026, featuring a collaboration with World Surf League pro surfer Kanoa Igarashi.

The watch was based on the G-LIDE GBX-H5600 model and featured a mixed-colour bio-based resin bezel and band inspired by cliffs in Portugal.

Casio equipped the timepiece with an optical heart rate monitor, tide graph, accelerometer, MIP LCD, and training analysis powered by Polar algorithms.

The model included Igarashi’s signature on the dial and case back alongside his surfer number 50 printed on the band.
