Casio uses generative AI to co-design structural components of G-Shock watches, with AI analyzing decades of shock-resistance data to propose optimized physical structures that human designers then refine. This practice began with a one-of-a-kind prototype in 2023 and expanded to a commercially available watch line in 2025.

In December 2023, Casio announced the G-D001, a one-of-a-kind 18-karat gold G-Shock created for the brand's 40th anniversary using generative design — a computer-aided design technique that uses AI to optimize physical structures. In May 2025, Casio announced the MTG-B4000, described as the first commercially available G-Shock watch with a frame designed using generative AI. For the MTG-B4000, human designers submitted initial structural concepts, and AI conducted load simulations using decades of accumulated G-Shock shock-resistance data, then proposed optimized 3D structural configurations based on factors including structural strength, material characteristics, and machinability. A third AI-assisted release, the full-metal GMW-BZ5000, was announced in late 2025 and launched in the US market, also using generative design and over 40 years of G-Shock shock-resistance data. In all cases, AI-generated designs were refined by human engineers and craftspeople before final production.
