G-SHOCK MTG Collection Bluetooth® Tough Solar Watch MTG-B4000-1AER

ABSOLUTE TOUGHNESS

Developed at a time when watches were still fragile instruments, G-SHOCK began with a young engineer who dreamed of "designing a watch that would not break even when dropped".

G-SHOCK has proven itself in every testing environment known to humankind; from extreme sports, temperatures as low as -30°, and even space. Favoured by police officers, athletes, astronauts, firefighters, mountaineers, and Special Forces units, these watches are genuine all-rounders and reliable companions in every situation.

Introducing the cutting-edge fusion of form and function with the MTG-B4000 where advanced metal components merge with the original G-SHOCK resin to redefine rugged sophistication.

The MTG-B4000 presents a next-generation Dual Core Guard structure, crafted with the support of artificial intelligence and a reimagined frame design that artfully blends carbon fibre and stainless steel. This revolutionary exterior sets a new standard, balancing durability and elegance in a bold design evolution. Blending AI innovation with expert human craftsmanship, this watch embodies a seamless integration of material, architecture, and aesthetic. Designers developed the base form, which was then enhanced through AI simulations to produce an optimised 3D structure—ultimately refined by hand to create a timepiece that unites functional performance with organic beauty. The frame’s dynamic, multi-dimensional shape is precision-cut from laminated carbon and glass fibre sheets, revealing a striking, layered visual. The stainless steel bezel components are meticulously finished with both hairline and mirror polishing, achieving a sophisticated and tactile contrast.

Engineered with Triple G Resist technology, the MTG-B4000 stands resilient against shock, centrifugal force, and vibration. The case back, crafted via metal injection moulding (MIM), adds structural depth and reinforces its robust character. Every detail is considered—from the high-clarity sapphire crystal to the finely crafted dial, produced using advanced processing techniques at Yamagata Casio. Built to perform as impressively as it looks, the MTG-B4000 offers smart connectivity via the CASIO WATCHES app, Bluetooth® pairing, Multiband 6 radio control, Tough Solar charging, and a high-brightness LED light. This is more than a timepiece—it’s a statement of technological artistry, ready to accompany you on any adventure.
