Casio EDIFICE EFK-100YD-3AJF Automatic Watch
📄 Product Description
The Casio EDIFICE EFK-100YD-3AJF blends motorsport aesthetics with advanced mechanical craftsmanship.
This 3-hand analog model captures the emotional spirit of racing machines through its electroformed forged carbon-textured dial, delivering both strength and refined beauty.
The hollow hour and minute hands feature luminous tips for excellent legibility in dark environments. Mirror-finished bar indexes and a precisely textured dial ring enhance the watch’s dimensional depth and premium appeal.
Equipped with a mechanical automatic movement (manual winding supported), this model provides an approximate 40-hour power reserve with daily accuracy between -35 and +45 seconds. The see-through screw back reveals the rhythmic motion of the 24-jewel movement, offering the pleasure of traditional mechanical watchmaking.
A solid stainless steel bracelet with slanted links ensures a seamless fit with the case, providing both comfort and durability. The sapphire crystal with inner anti-reflective coating offers scratch resistance and superior visibility.
