As the Casio G-Shock GMW-BZ5000 series continues its rollout to more countries, there’s a new rumor circulating that suggests the full-metal squares will receive a rainbow makeover in 2026. This leak indicates the upcoming limited-edition rainbow-ion-plated GMW-BZ5000RC-1, marking the first special release in the new BZ5000 collection.
Details About the New Model
According to the Instagram account @geesgshock, Casio is preparing a model named GMW-BZ5000RC-1, which is a rainbow ion-plated variant of the GMW-BZ5000. The post also notes that this model is a limited edition expected to be released between early to mid-2026, expanding the relatively new BZ5000 series beyond its basic finishes, which include silver, gold, and black.
Design Speculations
The image shared appears to be a user-created mock-up designed for visual appeal and not a true representation of the final product. There are no details about the dial layout, color blocking, or case-bracelet gradient currently available, so any design anticipations should be considered mere guesses.
For context, the GMW-BZ5000 series represents Casio’s latest high-end interpretation of the classic G-Shock square. The watches in this series come with an all-metal case and bracelet, equipped with a high-contrast MIP LCD, Tough Solar technology, Bluetooth connectivity, and Multi-Band 6 radio control. Previous variants have focused on standard metallic hues, so a rainbow-ion-plated RC-1 would serve as a standout piece, reminiscent of earlier “rainbow” models like the MT-G and GMW-B5000.
Availability and Pricing
At this time, Casio has not listed the GMW-BZ5000RC-1 on any official regional websites or limited-edition platforms, and there is a lack of press materials or pricing details available. Until more information surfaces, the only verified facts are the claimed reference number, the rainbow ion-plated design, and the approximate release timeframe of early to mid-2026. Details regarding materials, specific color schemes, market availability, and production quantities remain uncertain.
