New Casio G-Shock rainbow glass watch coming soon to the US

Casio has announced that the new G-Shock x XG GMAS110XG-4A and GMS5600XG-1 watches will be released in the US. The two collaboration models were unveiled in Japan at the end of May 2026.

Now, the Casio G-Shock GMAS110XG-4A is listed at the brand’s online store for $200. A product page for the GMS5600XG-1 at the Casio store indicates that this model will retail for $280. However, the brand has yet to confirm the release date of these XG collaboration watches in the US. As a reminder, these products are set to launch in Japan on June 12th, which could indicate a June release for the US market.

The seven members of XG, a hip-hop and R&B group, have been G-Shock ambassadors since July 2025. The band’s logo features on the dial of both the GMAS110XG-4A and GMS5600XG-1, and each model’s design has been influenced by the group. The GMAS110XG-4A has a bright pink resin casing and strap, with a glittering round hybrid dial. The GMS5600XG-1 features a rainbow vapor deposition glass surrounding a dark background digital display, with a pared-back matte black resin case and strap.

Casio’s digital-analog GMAS110 has two analog hands, a speed indicator dial and two inset digital displays. Functions include support for world time, a stopwatch, a timer and multiple alarms. The digital GMS5600 is a rectangular watch, with a black ion-plated stainless steel bezel. It has a similar feature set, with a less precise stopwatch, a timer and a single alarm. Plus, both models are water resistant to 200 m.
