Forged carbon with sporty functional beauty

EDIFICE is the first to use forged carbon, which is also used in luxury sports cars, for the dial and case. By incorporating a strong, lightweight, advanced material, the world of sports cars that continue to evolve in pursuit of further performance is expressed with EDIFICE-like styling.

Forged carbon

Developed in the aerospace field and increasingly used in the automotive industry, forged carbon is a composite material made by solidifying carbon fiber with resin and molding it under high temperature and pressure. It has high rigidity and lightweight properties, and is characterized by a beautiful marble pattern created during the manufacturing process.

Mechanical movement seen through the see-through case back

A mechanical movement is used to incorporate an emotional drive system like that of a car into the internal mechanism. The power reserve is approximately 40 hours, and the accuracy is an average daily difference of -35 to +45 seconds. The case back is see-through, so you can see the movement and enjoy the unique charm of a mechanical watch.

Dial design that delicately accentuates the elegant look

A simple dial with 3 hands + date display that highlights the design of forged carbon and other materials is adopted. The hollow hour and minute hands are luminous at the tip, achieving both sportiness and visibility in dark places. The sweeping second hand ticks away the time lightly. The texture has been enhanced in every detail, such as the mirror finish on the slope of the bar index and the grain processing on the dial ring. In addition to the two models with forged carbon dials, the lineup also includes a color dial model that expresses the texture of forged carbon through electroforming.

Urethane band for a light and comfortable fit

The forged carbon case is combined with a urethane band for a strong and lightweight all-black look. It features a three-fold D-buckle for easy fastening and removal.
