Casio's AI-Designed MTG-B4000 Watches Bring Carbon-Steel Hybrid Tech to US Market
Casio has officially launched its next-generation MT-G watches in the United States, introducing the MTGB4000-1A and MTGB4000B-1A2 models through the official G-Shock web store. The new timepieces represent a significant technological leap for the brand, incorporating artificial intelligence in the design process and featuring a revolutionary hybrid construction that combines carbon fiber with stainless steel elements.
The standout innovation lies in Casio's reimagined Dual Core Guard structure, developed with the assistance of in-house AI tools. Engineers have created a hybrid frame that fuses carbon-fiber plates with stainless-steel components, utilizing a screw-less lug arrangement designed to minimize shock transfer. This approach has resulted in a case measuring 56.6 × 45.3 × 14.4 mm that remains remarkably slim for an MT-G model while maintaining the series' robust 200-meter water resistance rating and G-Shock's Triple G Resist certification against shock, vibration, and centrifugal force.
The weight reduction achieved through this hybrid construction is notable, with both models weighing just 112 grams—considerably lighter than previous MT-G standards. This reduction comes from the carbon composite mid-case and the elimination of traditional metal screws at the lugs, creating a more comfortable wearing experience without compromising durability.
Casio has equipped the MTGB4000 series with comprehensive connectivity features, including Tough Solar charging that provides five months of autonomy in normal use, extending to 18 months in power-save mode. Multi-Band 6 radio reception ensures precise timekeeping by automatically syncing with atomic clock signals, while Bluetooth connectivity to the Casio Watches app enables one-touch world-time selection, phone finder functionality, automatic hand calibration, and access to approximately 300 city presets.
The watches cater to active users with a 24-hour stopwatch and countdown timer, making them suitable for athletes, travelers, and outdoor enthusiasts. Low-light visibility is addressed through a bright white Super Illuminator LED and Neobrite-filled indices. Premium construction details include a domed sapphire crystal with inner anti-reflective coating and a knurled screw-lock crown.
Market Reception and Availability
Both MTGB4000 models are now available for immediate purchase on the official G-Shock US website, with free domestic shipping and a standard one-year warranty that can be extended to three years through Casio's registration program. The launch comes after weeks of anticipation from US consumers who previously had to rely on overseas imports to access the latest MT-G technology.
However, the integration of AI in the design process has sparked debate among watch enthusiasts. Users on the aBlogtoWatch forum have expressed mixed reactions to both the design aesthetic and the use of artificial intelligence in timepiece development, suggesting that traditional watchmaking purists may need time to embrace this technological approach.
Given the rapid sell-outs experienced with previous MT-G releases, Casio advises interested buyers to act quickly, particularly those considering the stealthier B-1A2 colorway, which offers the complete feature set in one of the brand's darkest MT-G finishes to date. The MTGB4000 series positions itself as an evolution from the MTG-B3000 line, targeting users who sought more aggressive styling while maintaining the advanced functionality that has made the MT-G series popular among professionals and enthusiasts alike.
