Casio’s new MT-G B4000 pushes high-end G‑SHOCK models into future terrain, where AI and human design fuse. The MTG‑B4000B1A2 (blue‑gray IP finish, $1,350) and MTG‑B4000‑1A (brushed steel, $1,250) debuted July 2 via G‑SHOCK and select retailers.
Casio leveraged generative AI to optimize structural strength and material distribution. Designers fed sketches into machine learning, which then refined load points and geometry for a lightweight yet resilient carbon‑glass fiber and stainless steel frame.
A carbon-core Dual Core Guard structure features metal-injection-molded stainless steel parts with Sallaz-polished bezels and hairline textures. The layered carbon‑fiber frame reveals subtle depth along the case, especially on the IP‑coated B1A2 model.
Under the hood: Triple G‑Resist for shock, vibration, and centrifugal resistance; 200 m water resistance; Tough Solar + Multi‑Band 6 radio‑control; LED Super‑Illuminator and Bluetooth smartphone link via the CASIO app.
The MT‑G B4000 isn’t just a timepiece—it’s a showcase of next‑gen engineering. For men who value resilience and design, it captures both.
