Casio America has introduced the MTGB4000, the latest model in its premium MT-G lineup and the first timepiece developed using a blend of human design and generative AI optimization. The MTGB4000-1A and MTGB4000B1A2 feature a newly engineered Dual Core Guard structure that integrates the band connection into the frame, improving shock absorption and reducing stress on the inner case.
The bezel is crafted from laminated carbon and glass fiber sheets, creating a layered silhouette visible along the sides, while precision Sallaz polishing and alternating hairline and mirror finishes on the metal elements underscore the craftsmanship. The MTGB4000B1A2 adds a blue-grey ion-plated coating for a futuristic look. The case back is produced via metal injection molding for intricate, durable shaping, and a sapphire crystal with anti-reflective coating ensures clarity and scratch resistance.
Powered by solar charging, the new MTGB4000 models offer 200-metre water resistance, multi band 6 radio control, smartphone link functionality, world time for 27 cities, and a Super Illuminator LED. The triple-shock-resist and vibration-resist structure, along with auto hand home-position correction, stopwatch, countdown timer and alarm features, equip the watch for both rugged use and everyday wear.
