Casio’s First Mechanical Watch Ever - The Edifice EFK

#Casio #EFK‑100

A turning point in Casio history

The EFK‑100 is the first time Casio has equipped a mechanical movement in the EDIFICE line, which is famous for its motorsport-inspired design and analog-quartz technology. This is a sign that Casio has officially entered the traditional mechanical field.
The watch uses the Seiko NH35A automatic movement, with the ability to hand-wind, stop the second hand (hacking), has 24 jewels, a power reserve of about 40 hours, and a frequency of 3Hz.

Unique Design & Materials

The EFK‑100 retains EDIFICE’s “Speed ​​& Intelligence” design language, with dials made of forged carbon in some models (such as the EFK‑100CD‑1A), or recreated through electroforming (the EFK‑100D models) — creating a robust, refined look, each with its own unique pattern.
The 39 mm (or 40 mm for the XPB) steel case, scratch-resistant sapphire crystal, 100 m water resistance, and a transparent caseback allow you to admire the mechanical movement at work.
