The buzz around Casio’s upcoming rainbow ion-plated full-metal G-Shock square is getting louder, and the latest chatter is starting to fill in two critical blanks: how much it will cost and when we might see it.
According to a new update from the often-reliable leaker @geesgshock, the model—referenced as the GMW-BZ5000RC-1—could land with a price tag around £800 (approximately $1,069). The leak suggests the final figure may hover just under that mark, depending on the region. Perhaps even more notably, the same source points to an early-to-mid 2026 release window.
This gives us the clearest picture yet of what to expect from this highly-anticipated, eye-catching variant.
Putting the £800 Price Tag Into Context
This estimated price adds a crucial layer to earlier reports, which only confirmed the existence of a rainbow ion-plated version of the robust GMW-BZ5000 series. Until now, speculation on cost was wide-ranging, given the unique finish and expected limited availability.
If the £800 / ~$1,069 figure holds, it clearly positions the watch above the standard stainless steel and black ion-plated (IP) full-metal squares, which typically retail around the $500 mark. The premium is almost certainly attributed to the complex, multi-hued rainbow ion-plating process—a striking finish that’s far more intricate than a standard coating.
Yet, this price would likely place it below Casio’s most experimental or boutique G-Shock releases, which can venture well into the thousands. It seems poised as a premium, special-edition take on the beloved full-metal square silhouette.
Limited Availability Expected
The new leak reiterates that availability will be "relatively tight," with fewer units allocated per region. While not described as a numbered limited edition, the combination of restricted supply and a higher price point strongly suggests Casio will launch this as a special-run model rather than a permanent addition to the lineup.
For collectors and fans, this means acting quickly once official pre-orders are announced.
A recent social media post from a watch insider has given enthusiasts a closer look at the speculated finish. While not an official confirmation, the visual hints align with the leak details.

The Bottom Line
As always, none of this has been officially confirmed by Casio. The brand keeps its cards close, especially for flashy releases like this one. However, the emergence of a fairly specific price range and a release window means the rumor mill is moving from pure speculation to more concrete, discussable details.
We expect more leaks—and hopefully an official announcement—as we move closer to 2026. For now, the GMW-BZ5000RC-1 is shaping up to be a bold, premium, and likely hard-to-get highlight for G-Shock’s 2026 catalog.
