Casio EDIFICE Automatic Watch EFK-100YD-7AJF Mechanical Wristwatch
The Casio EDIFICE EFK-100YD-7AJF combines advanced craftsmanship and automotive-inspired design in a sleek mechanical timepiece. Featuring a forged carbon-textured dial created through electroforming, this 3-hand analog watch embodies both strength and precision. The hollow-style hands with luminous tips ensure excellent visibility in dark conditions, while the mirror-polished bar indexes and finely brushed dial ring enhance its refined look.
Driven by a reliable mechanical automatic movement with manual winding, this watch offers an approximate 40-hour power reserve and a daily accuracy of -35 to +45 seconds. The transparent screw-back case allows you to admire the movement’s rhythm — a hallmark of true watchmaking artistry.
Built for durability and comfort, the solid stainless-steel bracelet features slanted links for a seamless fit. The scratch-resistant sapphire crystal with anti-reflective coating ensures clear readability from any angle. With 10-bar water resistance and magnetic resistance (JIS Class 1), the EFK-100YD-7AJF is perfect for both business and leisure wear.
