FEATURES
Mechanical movement: Shown off with a see-through case back
To incorporate a drive system as passionate and dynamic as those that power sports cars, a mechanical movement has been introduced, offering a power reserve of around 40 hours and an average daily rate of -35 to +45 seconds. See-through case back design offers views of the movement in motion, offering the enjoyment of the unique charms of a mechanical watch.

Dial design: A refined look with fine detailing
Electroforming reproduces the look of forged carbon on the dial for a uniquely textured, refined look. The hour and minute hands, with hollowed sections and phosphorescent tips, blend a sporty aesthetic with excellent visibility in the dark. The sweep-motion seconds hand glides gracefully, marking the passage of time. Details such as a mirror finish on the beveled edges of the bar indexes and a ground finish on the dial ring enhance the watch with a sophisticated sense of texture.

DETAILS
Metal band for an elegant shine
A solid stainless-steel band accentuates the sense of unity with the metal case. Separate mirror and hairline finishes are applied to individual components, bringing out the luster of the metal.

Scratch-resistant sapphire crystal

EFK-100D-3ADR
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 100 meters leaves you free to focus on more exciting things.
