Casio’s latest full-metal G-Shock, the GMW-BZ5000RC-1, has officially arrived in the US after a phased release in Japan and Europe. Initially launched in Japan in April 2026, the watch became available in select European markets later that month before appearing on Casio’s global storefronts.
A Modern Take on a Classic Design
This model is part of the GMW-BZ5000 series, introduced in late 2025 as an evolution of the iconic 5000-series square design. What makes the RC variant stand out is its unique finish.
The watch features a full stainless steel build, including the case, bezel, and bracelet. Its centerpiece is a gradient rainbow ion-plated case, complemented by a subtle rainbow vapor-deposited ring around the display. Gold-colored screws on the bezel add contrast, while the case alternates between brushed and polished finishes. The rainbow effect is subtle when viewed head-on but becomes more pronounced from angled perspectives.
