Casio G-Shock 5000 Series Gets Rainbow Metal Design with Solar and Bluetooth
Casio has introduced the Casio G-Shock GMW-BZ5000RC-1 in Japan, adding a new design direction to its 5000 series. The model had surfaced in leaks earlier this year and is now listed on the company’s official store with a price of ¥121,000. A wider global release is expected, though timelines and regional pricing have not been confirmed.


The watch features a full-metal construction with a stainless steel case, bezel, and band. Its standout element is the center case, which uses a gradient rainbow ion-plated finish. This effect extends across the dial and is complemented by rainbow vapor deposition on the glass. Gold-colored ion-plated screws add contrast, while a mix of hairline and mirror finishes across components highlights the metal texture.
The structure combines the bezel and center case at the top and bottom, leaving the center case partially exposed. This design is supported by a resin internal protector that deforms under impact to absorb shocks. A screw-lock case back ensures a tight seal, maintaining G-Shock durability standards. The watch is also water-resistant up to 200 meters.



Casio says artificial intelligence was used alongside decades of shock-resistance data to refine the design and optimize component structure. The manufacturing process involves repeated forging, cutting, and polishing to achieve the final form. Production takes place at Yamagata Casio in Japan, the same facility that produced the original G-Shock.
The watch uses a high-definition MIP LCD with a negative display for improved clarity. Users can switch between multiple time display layouts and choose between STANDARD and CLASSIC font styles through a companion app. Bluetooth connectivity enables automatic time adjustment, while Multiband 6 radio control ensures accuracy.
Additional features include dual world time, a 1/100-second stopwatch, a countdown timer, and five daily alarms. The Tough Solar system supports continuous operation through light-based charging.
