Product Details
Description
The Casio Edifice EFK-100D-3AER is a mechanical men's watch that embodies the spirit of synergy between watchmaking and high-performance motorsport. The compact stainless steel case with a diameter of 39 mm houses an automatic movement with manual winding and an impressive power reserve of approximately 40 hours. The transparent screw-down caseback reveals the oscillating movement, lending the watch its distinctive character. The dial is finished using an electroplating process to achieve a forged carbon look — a uniquely textured appearance that is both sporty and elegant. The hour and minute hands with luminous tips ensure excellent legibility even in the dark, while a sweeping seconds hand completes the three-hand composition. The solid stainless steel bracelet is separately high-gloss polished and ultra-thinly coated to accentuate the seamless unity of bracelet and case. With water resistance up to 10 bar, this watch is well equipped for an active lifestyle. The scratch-resistant sapphire crystal rounds off the premium overall package.
