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-colour 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 vapour deposition on the watch face.

Equipped with tide graph function, optical sensor to measure heart rate and analyse 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 fibre-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-colour moulding, there are individual differences in colour and pattern in every timepiece.

Kanoa Igarashi

Influenced by his parents, Igarashi began surfing at the age of three in his hometown of Huntington Beach, California. Including his junior career, Igarashi went on to set a series of remarkable records across the United States. In 2016, he qualified for the world’s premier professional surfing circuit, the WSL Championship Tour (CT), becoming the youngest surfer in history to compete at that level. In 2019, at the third event of the CT season, he claimed his first career victory — also marking the first-ever CT win by an Asian surfer.

In 2021, Igarashi represented Japan in the surfing competition at the Tokyo 2020 Olympic Games, the first year the sport was featured as an official event, and won the silver medal. At the 2022 ISA World Surfing Games, Igarashi won a perfect first place in all eight of the heats to capture his long-sought World Champion title.

In the 2025 CT season, Igarashi reinforced his status as one of the world’s elite surfers with a 7th-place finish in the WSL world rankings. With his sights set on the CT World Title, he continues to sharpen his performance as he prepares for the upcoming Olympic Games in Los Angeles, his hometown.

Colour scheme inspired by Portuguese sea cliffs

Mixed-colour moulding in brown tones expresses landscapes from Portugal — one of Igarashi’s home and training bases — such as the cliffs and rocky shores surrounding the renowned surf destination of Ericeira. Combined with a tide graph depicting ocean waves, this achieves a design befitting a G-LIDE. An accent colour of purple evokes the “magic hours” of early morning and twilight when the sky appears to be painted colourfully.

Design details imbued with Igarashi’s individual identity

Igarashi’s signature is incorporated into the design on the watch face and case back, and Igarashi’s surfer number, 50, adorns the band — special design features for a collaboration model emphasising the connection between surfers and G-SHOCK.

Diverse functions to support athletic use

Based on the GBX-H5600, the watch is equipped with a heart rate monitor and accelerometer to provide measurement functions that support four different activities, along with a tide graph, moon data, and more. The MIP LCD provides high-definition display of diverse measurement data. Training and sleep analysis powered by Polar’s algorithms is included as well. A watch equipped to support intense use day after day.

Smartphone Link

Smartphone pairing via Bluetooth® delivers automatic time correction and makes it easy to configure tide graph settings from the app. Tracked data can also be sent to a paired smartphone and checked in training logs and life logs. Detailed training and sleep analysis data and more can be reviewed as well.

Bio-based resin

Key resin components used in the bezel, case, and band are made with bio-based resin, a material expected to help reduce environmental impact.
