Casio announced a new collaborative and limited G-Shock release with environmental NGO Surfrider Foundation Japan. The yellow G-5600SFJ-9 follows 2024’s black G-5600SRF-1, and like that model, it is a Tough Solar-powered G-5600 watch.
Although they share a similar style and similar logos on the face and case back, one difference is that last year’s model was with the original California-based Surfrider Foundation and this year’s is with Surfrider Foundation Japan, which was incorporated in 2011. (It’s not known if this Japan edition will be sold in the West, but it’s also listed on the Casio international site for Asia.) The yellow color is inspired by the theme of “Sunrise Surf,” and the bezel and band are made of mix-molded yellow and light yellow bio-based resin, giving each individual watch a uniquely marbled appearance.
The G-5600SFJ-9JR will be released in Japan in June 2025 for 20,900 yen.
