Casio G-Shock - GBX-H5600KI-5A G-LIDE Kanoa Igarashi 2026

Pro surfer and G-SHOCK ambassador Kanoa Igarashi returns with his fourth signature timepiece! Inspired by the cliffs of Portugal, one of Igarashi’s home training bases, this latest collaboration features a two-color bio-based resin bezel and band that complement everyday fashions. Accents in the lavender hues of the ocean at the magic hour that he loves so much are rendered in vapor deposition on the watch face.

Equipped with tide graph function, optical sensor to measure heart rate and analyze training sessions, and high-definition, high-contrast memory-in-pixel (MIP) LCD for outstanding readability even in direct sunlight and under water, this special timepiece delivers all you need not just for ocean fun, but running, walking, and other daily workouts, as well. Thanks to a case back made of carbon fiber-reinforced resin, the watch is about 18 grams lighter than the previous model with built-in heart rate monitor (DW-H5600), for a truly comfortable feel and fit even at your most active.

With Igarashi’s signature throughout, as well as the number 50, his surfer number in the world’s ultimate pro-surfing series, this impressively detailed design is sure to inspire the intrepid ocean-goer in you. * Due to the characteristics of mixed-color molding, there are individual differences in color and pattern in every timepiece.

■Kanoa Igarashi

Born October 1, 1997, in California, USA. Igarashi grew up watching his dad surf every day in Huntington Beach, California. At the age of 3, he was done watching and jumped in the water himself. He was an instant talent and quickly commanded the attention of the surfing community. In 2009, at 11 years old, Igarashi gained National Scholastic Surfing Association (NSSA) fame by claiming a stunning 30 contest wins to set a new record for the most victories in a single season. In 2012, at the age of 14, he became the youngest ever to win the USA Championship Under-18. Four years later, he was the youngest ever, and first Asian, to participate in the World Surf League (WSL) Championship Tour. In 2017, Igarashi won the WSL Vans U.S. Open of Surfing, held in his hometown of Huntington Beach, as he continued to show the world what he could do. In 2019, he was the first Asian to claim victory at the Corona Bali Protected, the third event of the Men’s Championship Tour. In 2021, Igarashi represented Japan in the surfing competition at the Tokyo 2020 Olympic Games, winning a silver medal.
