Casio has just dropped the G-Shock MTG-B4000, a watch that doesn’t just tell time – it tells the future of design. By combining human creativity and generative AI, Casio has crafted a timepiece that pushes the limits of G-Shock’s shock-resistant DNA while introducing a frame unlike anything in its history. Available in Singapore from August 22, the MTG-B4000 blends cutting-edge engineering with bold street-ready style.

Co-created with generative AI

The MTG-B4000’s frame is the first in a Casio consumer watch to be co-created with generative AI. Starting with proposals from human designers, AI ran load simulations based on decades of G-Shock data, then suggested structural configurations optimized for strength, material performance, and machinability. The result? A layered frame cut from carbon and glass fiber sheets, showing off a striking side pattern, topped with a refined metal bezel polished to perfection. The new integrated band connection absorbs impact directly, further enhancing durability.

Beyond the tech

This drop isn’t just about tech — it’s about a new design philosophy. Casio’s purpose of “putting wonder at hand” comes alive through AI collaboration, redefining what shock resistance can look like. The MTG-B4000 is both experimental and practical, embodying innovation without compromising on toughness. It’s a glimpse into how human creativity and machine intelligence can build together.
