Durable Design: A Carbon and Stainless Steel Hybrid
The new MTG-B4000D-1AJF features a multi-layer construction, combining a carbon fiber-reinforced resin bezel with a stainless steel exterior. Casio calls this advanced technology “Dual Core Guard,” and it’s designed to provide exceptional shock absorption while maintaining the strength and durability associated with metal structures. This approach to watchmaking reflects a broader trend in combining materials for enhanced performance and resilience.
Even the watch’s metal bracelet utilizes an innovative hybrid structure. While appearing entirely metallic, it’s actually composed of layers of reinforced steel integrated with resin components. This design effectively balances lightweight comfort with optimal rigidity, resulting in a total watch weight of just 178 grams.
