Innovation Meets Precision: G-SHOCK Debuts MT-G Watches Designed by Humans and AI

New MTG Series Introduces Newly Developed Structure Using Advanced Materials and Innovative Technology

DOVER, N.J., July 2, 2025 /PRNewswire/ -- Today, Casio America, Inc., is excited to unveil the MTGB4000, the newest addition to its premium MT-G lineup and the first G-SHOCK timepiece developed through a design process combining human ingenuity with generative AI technology. This launch marks a new era of innovation in watchmaking, where advanced computational design meets G-SHOCK's signature shock-resistant engineering.

The MTGB4000-1A and MTGB4000B1A2 debut a newly developed, distinctive frame that redefines G-SHOCK's iconic toughness and refined craftsmanship. Development began with initial sketches from G-SHOCK's designers, which were then optimized using AI to enhance structural performance while preserving the bold aesthetics of the MT-G line. The result is a timepiece that achieves a new harmony of strength and elegance, pushing the frontiers of functional beauty, delivering both rugged durability and elevated visual appeal.

Building off of the MT-G line's signature construction, the new launch combines the strength of metal and resin for a bold yet functional design. This new model features an evolved Dual Core Guard structure with integrated band connection parts, allowing the frame to absorb external shocks and reducing the load on the inner case. This innovation further enhances the MTGB4000's shock resistance while giving the watch a bold and cohesive form.

The frame is cut from laminated carbon and glass fiber sheets, producing a dimensional silhouette with visible layering along the sides. The top of the bezel is adorned with precision finishes, including Sallaz polishing, a high-end technique that produces smooth, distortion-free mirror surfaces. Contrasting hairline and mirror finishes highlight the craftsmanship behind each metal detail, adding richness and depth to the overall design. The MTGB4000B1A2 is further distinguished by a newly developed blue-gray IP coating, offering a rich, futuristic aesthetic.

Crafted using metal injection molding (MIM), the case back features intricate shaping and a highly durable form. Clarity and scratch resistance come courtesy of a sapphire crystal with anti-reflective coating, while the multi-dimensional dial is expertly produced through precision processing at Yamagata Casio.

The new timepieces come equipped with the following features: 

• Triple G Resist Structure (Shock-resistant)
• Centrifugal gravity resistant (Vibration-resistant)
• 200 Meter water resistance
• Tough Solar power
• Smartphone Link
• Radio-controlled (Multi band 6)
• Auto hand home position correction
• World time (27 cities)
• Stopwatch
• Countdown timer
• Alarm
• LED light (Super Illuminator)

The MTGB4000-1A ($1,250) and MTGB4000B1A2 ($1,350) will be available for purchase on July 2^nd at select Retailers, gshock.com, and the G-SHOCK Soho store. For more information about the G-SHOCK brand, visit gshock.casio.com/us. 

About G-SHOCK

CASIO's shock-resistant G-SHOCK watch is synonymous with toughness, born from the developer Mr. Ibe's dream of 'creating a watch that never breaks'. Over 200 handmade samples were created and tested to destruction until finally in 1983 the first, now iconic G-SHOCK hit the streets of Japan and began to establish itself as 'the toughest watch of all time'. Each watch encompasses the 7 elements; electric shock resistance, gravity resistance, low temperature resistance, vibration resistance, water resistance, shock resistance and toughness. The watch is packed with Casio innovations and technologies to prevent it from suffering direct shock; this includes internal components protected with urethane and suspended timekeeping modules inside the watch structure. Since its launch, G-SHOCK has continued to evolve, continuing to support on Mr. Ibe's mantra "never, never give up." www.gshock.casio.com/us/
