Casio G-Shock MT-G MTG-B4000B-1AJF JDM | Carbon & Metal Premium Bluetooth Tough Solar (Made in Japan)

Product Description

Cutting-edge engineering and AI-assisted design: The perfect balance between luxury and absolute durability.

The Casio G-Shock MT-G MTG-B4000B-1AJF is a high-end timepiece manufactured exclusively at the high-precision facilities of Yamagata Casio for the Japanese Domestic Market (JDM). This model revolutionizes the MT-G series by incorporating an enhanced Dual Core Guard structure, developed with the help of Artificial Intelligence to simulate and optimize impact resistance. The result is an ultra-durable organic case that fuses layers of textured carbon with a stainless steel bezel featuring a Black Ion-Plated (IP) finish with mirror and satin finishes.

Equipped with the legendary TRIPLE G RESIST protection (capable of withstanding impacts, centrifugal force, and extreme vibrations), this sophisticated analog model features sporty red accents on its three-dimensional dial, protected by a sapphire crystal with an anti-reflective coating for maximum clarity.

🛡️ Premium Technology and Construction

• Triple G Resist + Carbon Core Guard Structure: Designed for aviation and the harshest environments; withstands drops, extreme G-forces, and continuous vibrations.
• Yamagata Premium Production: Intricate dials and internal components manufactured using precision micro-machining technology at Casio’s luxury factory in Japan.
• MIM Monoblock Bezel: Three-dimensional case back created using Metal Injection Molding (MIM) that wraps around the structure for a perfect seal and a sleeker profile (only 14.4 mm thick).
• Sapphire Crystal: Premium crystal with internal anti-reflective coating, virtually scratch-proof.

🔋 Connectivity and Smart Features

• Hybrid Synchronization (Bluetooth + Multi-Band 6): The watch automatically adjusts to the exact time worldwide by connecting to a smartphone or by receiving radio waves from atomic clocks (U.S., U.K., Germany, Japan, and China).
• Tough Solar: High-efficiency solar charging system that provides up to 18 months of battery life in the dark with the power-saving function activated.
• Smart Link App (CASIO WATCHES): Simplified world time setup for over 300 cities, phone finder, watch status self-check, and Time & Place location logging.
