At this point, everybody can agree that AI is not the magic wand we were promised would improve every aspect of life.

It clogs up our social media feeds with slop, routinely provides inaccurate answers, frustrates routine work tasks and threatens the stability of all creative arts, democratic governments and trust in news media.

However, when utilized as a tool to enhance human creativity with extremely complex computation and data analysis, as it is meant to, generative AI can indeed make life easier.

Better still, it can help create some really cool stuff. Take, for example, the newest addition to G-Shock’s MT-G collection, the B4000.

Casio’s design team fed initial plans into a machine learning program, which enhanced the structural performance of the selected materials beyond what human engineers had achieved.

As Casio puts it, the MT-G B4000 contains a “newly developed, distinctive frame that redefines G-SHOCK’s iconic toughness and refined craftsmanship.”

It is made of laminated carbon and glass fiber sheets, shaped to maximize shock resistance and structural stability while minimizing weight.

Layers of protection

All G-Shock’s top-end models, including the luxurious MR-G and technical MT-G lines, contain a core case structure secured to a frame by a bezel and caseback.

The MT-G B4000 utilized the same metal injection molding process that G-Shock has used for years on the caseback and bezel. This process allows for intricate steel shaping at a thinness that would be nearly impossible to achieve with conventional tooling.

Where the AI assisted Casio’s design team was with the frame that holds everything together, including the integrated resin strap, and acts as the first line of defense against concussion and abrasion damage.

The generative AI program created a shape for the laminated carbon and glass fiber frame that maxed out the strength-to-weight ratio based on the physics of impact damage.

The works

In reality, the AI-assisted case design is just window dressing because 95 percent of the MT-G B4000 is pure G-Shock, as we’ve all come to know and love it, at its highest level.

The analog dial, akin to the much-adored “CasiOak,” is sneakily packed with timekeeping features. Along with the active time, there is a 24-hour chronograph, timer, alarm, world time, calendar and alarm.

An LED backlight illuminates the full dial, and a battery indicator displays the charge on the Casio Tough Solar quartz movement. The time is accurate to +/- 15 seconds per month, far outperforming all but the most expensive mechanical watches.

Regardless of how much AI input was involved in the design of this watch, which honestly wasn’t much, it is easily one of the best G-Shock models available.

As is expected of Casio, even this top-shelf watch with a sleek, modern look and all the features you could ask for is relatively affordable at no more than $1,350.

Availability and pricing

The Casio G-Shock MT-G B4000 is available now from G-Shock.

The brushed steel reference B4000-1A costs $1,250, and the blue-gray IP-coated steel reference B4000-B1A2 costs $1,350.
