Fresh buzz around Casio’s upcoming rainbow ion-plated full-metal square G-Shock is starting to answer the question everyone’s been debating: how much will it cost? A new round of leak chatter now points to the model being referenced as the GMW-BZ5000RC-1, with an expected price hovering around £800 (roughly $1,069). Depending on the region, it could even arrive just under that number. The same information also suggests an early-to-mid 2026 launch window, meaning this striking full-metal square could still be some months away.
Until now, the rainbow ion-plated version of the GMW-BZ5000 series has been more mystery than certainty. Earlier talk confirmed the existence of the finish, but didn’t clearly place it in Casio’s pricing ladder. That gap left plenty of room for speculation, especially because rainbow-style treatments are the kind of detail brands often reserve for smaller runs or special drops.
If the £800 estimate proves accurate, it would put the GMW-BZ5000RC-1 well above the usual full-metal square options. Standard stainless steel and black ion-plated full-metal models typically sit far lower, often around the $500 range. The big difference here is the rainbow ion plating, which is expected to be the main reason for the higher price. It’s the kind of finish that’s designed to turn heads and spark conversation, and Casio rarely applies treatments like this without charging a premium.
Another detail getting repeated in the latest leak: availability may be tight. That doesn’t necessarily mean it will be sold as a numbered limited edition, but restricted allocation by region can create a very similar outcome in the real world—fewer pieces in stores, quicker sell-outs, and more demand from collectors who don’t want to miss the drop. Combined with the higher-than-normal price, it sounds less like a permanent catalog addition and more like a special-run release aimed at enthusiasts.
None of this has been officially confirmed by Casio yet, so it’s still best treated as informed speculation. Still, the appearance of a specific price range alongside a potential early-to-mid 2026 release window is a sign that clearer details on the Casio GMW-BZ5000RC-1 could surface soon.
