The G-Shock rumor mill is spinning at full speed this week, and for fans of the iconic full-metal square, it looks like Casio is preparing to drop one of the most visually intriguing releases of the year.
A fresh leak shared by the reliable tipster @morgan_gshock has surfaced, giving us our clearest and most detailed look yet at the upcoming Casio GMW-BZ5000RC-1DR. Following earlier murmurs of a rainbow-colored metal square, this new spec sheet render clarifies the design language—and it appears the final product is more refined (and restrained) than early speculation suggested.
A “Restrained” Rainbow: The Design Breakdown
Unlike the fully multicolored cases some enthusiasts anticipated, the new render reveals a watch that leans heavily on contrast. The GMW-BZ5000RC-1DR features a full stainless steel construction with a matching metal bracelet, maintaining the premium heft that fans of the full-metal series expect.
However, the "RC" (presumably standing for Rainbow Coating) designation comes into play with a subtle, sophisticated application of color. Rather than a vibrant case, the watch showcases a subtle rainbow ion-plated (IP) finish that catches the light along the edges of the case and the dial frame.
Looking closely at the leaked specifications sheet:
- Cool Tones: Deep blue and purple hues are highly noticeable along the lower right flank of the case.
- Warm Tones: Warmer shades of red and orange fade in closer to the top of the bezel.
- The Dial: The inner frame surrounding the digital screen carries a faint multicolor gradient, tying the package together without being overly loud.
It appears Casio has opted for a "stealth wealth" approach to color, where the rainbow effect reveals itself primarily when light hits the angular surfaces of the square case.
Tech Specs: Familiar Excellence
For collectors wondering if this special edition introduces new hardware, the spec sheet confirms that the GMW-BZ5000RC-1DR will retain the powerhouse features that define the high-end G-Shock square lineup.
According to the documentation, the watch includes:
- Tough Solar charging
- Multi Band 6 radio-controlled timekeeping
- Bluetooth connectivity for seamless smartphone pairing
- 20 Bar water resistance
- Mineral Glass (common in the metal squares to maintain impact resistance)
- White LED backlight
New Module Number and Release Window
While the core features remain standard, there is a new detail eagle-eyed collectors will note: the module number listed is 3575.
This suggests a minor revision or a variant of the current platform. While Casio has not specified what changes this brings to daily use (it could be power efficiency or a tweak to the display logic), it confirms that this isn’t simply a repaint of an existing model.
Additionally, the presence of an "APR" marking on the documentation hints strongly at an April release window. If the leak holds true, the official announcement could be just weeks away.
Pricing and Availability
Pricing details were not mentioned in this specific leak, but earlier reports from European retailers have pointed toward a figure around €800.
Given the special rainbow IP finish and the limited nature of previous "RC" models, the GMW-BZ5000RC-1DR is expected to see limited availability rather than a widely stocked general release. Collectors anticipating this piece will likely need to act fast when it drops.

The Bottom Line
The Casio GMW-BZ5000RC-1DR appears to be a masterclass in subtlety. By limiting the rainbow effect to the edges and the dial frame rather than coating the entire case, Casio may have created a versatile everyday luxury watch that catches the eye without sacrificing the utilitarian aesthetic the square is known for.
In the meantime, if you are looking to add a classic full-metal square to your collection today, the standard model remains a fantastic choice.
