Casio introduces new premium MTG-B4000D watches with stainless steel case and up to 1.5 years of autonomy

Casio introduces the new premium watches MTG-B4000D-1AJF — a flagship model of the MT-G line that combines metal, carbon fiber, and proprietary protective technologies.

What is known

The MTG-B4000D received an updated Dual Core Guard construction, where a carbon frame absorbs shocks, and external stainless steel elements provide rigidity and protection. This hybrid approach made the case both durable and visually more "premium." The bracelet is also made using composite technology, which reduces weight without sacrificing strength.

Model dimensions — 56.6 × 45.3 × 14.4 mm.

The watch supports Tough Solar solar charging, Bluetooth time synchronization, and the Multi Band 6 system. Among its features are world time, stopwatch, timer, alarms, LED backlight, and automatic calendar. The declared autonomy reaches 1.5 years in power-saving mode. The model withstands immersion in water up to 200 meters deep.

Sales of the MTG-B4000D will start in January 2026, but pre-orders are already open in Japan at a price of about $1190.
