EDIFICE EFK-100YD — Mechanical Automatic, Forged Carbon Dial

EDIFICE AUTOMATIC / EFK-100 Series / Released July 2025

From EDIFICE's ongoing pursuit of the affinity between motorsport and watches comes this 3-hand analog model featuring a distinctively patterned dial. The dial expresses the texture of forged carbon, while hollow-shaped hour and minute hands with luminous tips balance a sporty look with visibility in low light. Mirror-finished bar index edges and a fine machine-turned dial ring add refined detail throughout. At its heart is a mechanical movement, viewable through the see-through case back — a genuinely mechanical watch experience. The solid stainless steel band gets slanted case-side edges for a more integrated feel with the case, and inner anti-reflective coated sapphire glass resists scratches while ensuring high visibility.
