Casio Edifice EQB-1300DC-3A, EQB-1300D-2A, and EQB-1300D-5A with Sapphire Crystal

Combining high-performance engineering with a sleek, minimalist aesthetic, the Casio Edifice EQB-1300 series represents the pinnacle of the "Speed and Intelligence" philosophy. This flagship lineup—comprising the EQB-1300DC-3A, EQB-1300D-2A, and EQB-1300D-5A—is designed for those who demand the precision of professional motorsports alongside the refinement of a luxury timepiece.

Design and Dimensions


The EQB-1300 series is built upon the concept of "Intelligent Functional Beauty." Drawing inspiration from the high-octane world of motorsports, the design evokes the sophisticated interiors of high-end sports cars. Every element, from the curved fluid lines of the case to the shimmering metallic finish of the dials, is crafted to reflect the exhilaration of driving and the precision of automotive engineering.

The most striking feature of the EQB-1300 is its remarkably slim profile. Despite housing complex Bluetooth® and solar technology, the case measures a mere 9.5 mm in thickness. With a diameter of 39.5 mm and a lug-to-lug length of 46.5 mm, the watch offers a compact and comfortable fit that slides easily under a suit cuff while maintaining a strong presence on the wrist.

The exterior is a study in material contrast. The bezel features a mirror finish on its sharp contours, juxtaposed against a circular hairline finish on the top surface. This meticulous attention to detail highlights the substantial feel of the solid stainless steel case. Protecting the face is a Sapphire Crystal with an anti-reflective coating, ensuring maximum scratch resistance and crystal-clear visibility under any lighting condition.

Complementing the case is a solid stainless steel H-link band. The links are designed with short spacing to enhance wrist ergonomics and are finished with the same blend of mirror and hairline polishing found on the case. Each model features a one-touch, three-fold clasp for secure and easy wear.

Dial Texture and Color

The dials are the centerpiece of this series, featuring a sophisticated texture created with ultrafine lines and lustrous metallic finishes. This design allows for a "light-transmissive" functionality, meaning the dial looks as solid as metal while still allowing light to reach the solar panels beneath.
The EQB-1300DC-3A features a deep, racing-green dial set against a gray ion-plated case and band for a stealthy, modern look. Meanwhile, the EQB-1300D-2A showcases a classic, vibrant blue dial that echoes the traditional colors of luxury grand tourers. Finally, the EQB-1300D-5A offers a unique, elegant brown dial that provides a warm, sophisticated alternative to traditional watch colors.

Functions and Features

Equipped with Casio’s Tough Solar power system, these watches convert even weak light sources into energy, eliminating the need for battery replacements. The Smartphone Link feature via Bluetooth® ensures the watch is always accurate by automatically adjusting the time four times a day when paired with the CASIO WATCHES app.

The watch is equipped with several advanced features, including a 100-meter water resistance rating that makes it suitable for swimming and everyday exposure to water. Its integrated chronograph functions as a precise 1-second stopwatch with a 30-minute measuring capacity for timing various activities. For added convenience, a dedicated Phone Finder button allows you to trigger a tone on your smartphone if it ever goes missing nearby.

The Time & Place feature enables you to record the current date, time, and exact map coordinates within the app at the press of a button, serving as a highly functional travel or activity log. Finally, the watch includes a full auto-calendar that is pre-programmed to remain accurate until the year 2099.

The series utilizes a high-precision solar-powered quartz movement with an accuracy of ±15 seconds per month (without the mobile link). The power-saving function ensures that the hands stop to conserve energy when the watch is left in the dark, allowing it to run for up to 18 months on a full charge in total darkness.

The Casio Edifice EQB-1300 series is more than just a timekeeper; it is a sophisticated tool for the modern professional. By blending ultra-slim design with robust solar technology and smart connectivity, Casio has created a timepiece that transitions seamlessly from the boardroom to the racetrack. Whether you choose the striking green of the DC-3A, the classic blue of the D-2A, or the refined brown of the D-5A, you are wearing the embodiment of speed and intelligence.
