Discover the fusion of motorsport engineering and precision watchmaking with the Casio EDIFICE EFK-100YCD-1AJF Automatic Watch.
Inspired by the world of high-performance sports cars, this model features a forged carbon dial that evokes the texture and strength of carbon fiber used in luxury vehicles.
Driven by a mechanical automatic movement (with manual winding capability), this timepiece delivers approximately 40 hours of power reserve and offers the emotional experience of viewing the intricate movement through the see-through screw back.
The dial features a simple yet sophisticated three-hand design with date display, complemented by hollow hour and minute hands with luminous tips for enhanced legibility in low light. A smooth sweeping second hand and precisely finished mirror bar indexes elevate the watch’s sporty and refined aesthetic.
