Crafted for true sports car enthusiasts and GT car fans — the EFK-100D, a sleek three-hand analog watch, embodies the EDIFICE spirit of synergy between timepiece engineering and the world of high-performance cars.
Electroforming reproduces the look of forged carbon on the dial for a uniquely textured, sporty, yet refined look. The sapphire crystal enhances visibility, while dynamic touches like raised indexes and sharp bezel and case complete the sophisticated design.
The mechanical movement with 40-hour reserve powers the watch hands like a humming sports car engine, all housed in a compact 39mm case. The see-through case back reveals the movement in motion, reinforcing the unique charms of a mechanical watch.
Water resistance up to 10 bar leaves you free to focus on more exciting things.
