Casio just launched the MTG-B4000 series in Japan, the first G-Shock watches designed with help from artificial intelligence.
The MTG-B4000 uses AI to create its frame structure. Casio fed the AI years of shock-resistant data from G-Shock development, then had it design the Dual Core Guard structure that mixes carbon frames with stainless steel parts. The process works like this: designers make a basic concept, AI analyzes it and builds optimized 3D models, then designers refine it by hand. They repeat this until they get the right balance of function and looks.
The carbon frame starts as sheets of carbon and glass fiber layered together, then cut into complex 3D shapes. You can see the layered pattern where the two materials meet. This frame connects with the metal bezel, side buttons, and back cover to create the overall look.
The stainless steel bezel has two layers with different finishes. Some parts get Zaratsu mirror polishing for a smooth, distortion-free surface. Other parts get hairline finishes. The back cover uses Metal Injection Molding, where powdered metal gets injected to form the 3D shape.
The dial has multiple layers for depth. It combines slanted rings with big raised indices that have sharp, multi-sided shapes. The indices get a luminous coating and metallic deposition. Casio uses micro-machining technology to make these precise parts.
The watch measures 56.6 x 45.3 x 14.4mm and weighs 112 grams. It passes Triple G Resist testing for shock, centrifugal force, and vibration resistance. Water resistance goes to 20 ATM.
For timekeeping, it has Multiband 6 radio reception that works in Japan, North America, Europe, and China. It also connects to smartphones via Bluetooth using the CASIO WATCHES app for automatic time updates and other functions like world time for about 300 cities.
The Tough Solar charging system runs about 5 months without light, or 18 months in power-saving mode. The sapphire crystal has an anti-reflective coating, and the LED light is white with afterglow. Standard features include world time for 27 cities, a stopwatch, a timer, and an automatic calendar.
Two models are available: the MTG-B4000B-1A2JF costs ¥176,000 ($1,220) and has a blue-gray IP coating. The MTG-B4000-1AJF costs ¥165,000 ($1,144) with regular metal finishing. Both launch in June 2025 and are only available in Japan through Casio’s website.
In other news, Casio has also unveiled the limited edition Oceanus Manta OCW-S6000PB-7AJF watch, which is set to hit Japanese markets in June 2025 at ¥385,000 (~$2,700) with only 600 units available. The watch features a sapphire glass bezel with 12 outer facets and 60 concave cuts, treated with blue and platinum vapor and sputtering finishes to mimic the sea-sky horizon.
