Casio’s premium G-Shock MTG-B4000B-1A has started appearing in the U.S. through retailer Arizona Fine Time. The watch is the latest model in the MTG-B4000 series, which also consists of the MTG-B4000B-1A2JF and the MTG-B4000-1AJF.
The watch is listed at $1,500 and appears to be shipping immediately. That puts it at the same U.S. retail price as the older MTG-B4000B-1A2. In Japan, the related MTG-B4000B-1AJF launched on May 15, 2026, priced at ¥176,000, or about $1,110.
The MTG-B4000B-1A is part of Casio’s MT-G line, which combines resin and metal construction. This model uses a carbon laminated frame with stainless steel, along with a Dual Core Guard structure. Casio says the design was refined through simulation and human review to balance strength, shape, and wearability.
The case uses carbon fiber reinforced resin and stainless steel, while the bezel has a two-part inner and outer structure. The stainless-steel bezel gets black ion plating with both hairline and mirror finishes. The case back is made from stainless steel using Metal Injection Molding. The watch also has Triple G Resist protection, covering shock, centrifugal force, and vibration resistance.
The black dial carries red accents and microfabrication details from Casio’s Yamagata factory. It is protected by a sapphire crystal and paired with a black soft urethane band. Other hardware details include a screw-lock crown, Neobrite luminous treatment, a high-brightness LED light, and 200-meter water resistance.
For timekeeping, the quartz watch supports Multi Band 6 radio-controlled adjustment and Bluetooth syncing through the Casio Watches app. App features include automatic time correction, phone finder, watch status display, self-check, Time & Place logging, and world time for around 300 cities. Like most G-Shocks, the MTG-B4000B also uses Tough Solar charging, and can last for around five months without seeing the sun, or up to 18 months in power-saving mode.
