Casio Edifice Automatic EFK-100CD-1AER

Casio's First Automatic Watch - A Groundbreaking Combination of Precision, Power, and Sports Car-Inspired Design

The Beginning of a New Era

The Casio Edifice EFK-100CD-1AER represents a historic milestone: Casio's first automatic watch series. This model combines Casio's excellence in technical watch design with a mechanical movement that pulses like the engine of a GT race car.

Designed for GT car enthusiasts

Housed in a sleek and compact 39mm steel case, the EFK-100CD captures the design language of high-performance sports cars. The molded carbon-fiber-replica dial, created using electroforming, brings sporty edginess and refined detail to the surface.

The sapphire crystal offers durable scratch protection and excellent clarity, while the shiny steel bracelet combined with the convenient one-touch clasp completes the whole with style and comfort.

Mechanical movement and transparent charm

At the heart of the watch ticks Casio's own automatic movement - an automatic movement with manual winding. This 24-jewel movement vibrates 21,600 times per hour and offers up to 40 hours of power reserve.

The transparent screw-locked caseback on the back of the watch gives you a glimpse into the live movement of the mechanism – like watching a sports car engine in action.

Designed for movement and durability

As befits the Casio EDIFICE series, the EFK-100CD is not just a showy outer shell – it has all the necessary features:

• 100 m (10 bar) water resistance, suitable for swimming and active everyday life
• Magnetic protection to ensure operational stability
• Date display, stop second hand function and accuracy of -35 – +45 seconds per day
