Casio Introduces G-Shock GMW-BZ5000RC-1 With Rainbow Finish

Casio introduced the G-Shock GMW-BZ5000RC-1 in Japan on April 3, 2026, listing it at ¥121,000 on its official store with a wider global release expected. The full-metal watch features a gradient rainbow ion-plated center case, rainbow vapor deposition on the glass, and gold-colored accents; Casio says it used artificial intelligence with decades of shock-resistance data to refine the design and structure.
Scoring Rationale
Official product announcement from Casio scores moderate for credibility and relevance to consumer-electronics; novelty is limited to a new model and finish, while AI-driven design details add slight technical interest, so overall impact is notable but industry-segment focused.
