Casio, long associated with quartz and digital technologies, surprised everyone by announcing an automatic collection. For the first time, the Japanese company introduced an automatic mechanical movement within its Edifice range, thus demonstrating new horological ambitions.
A historic turning point
Since the end of World War II, Casio had focused exclusively on electronic components, computers, and calculators. After its foray into watchmaking in 1974 with the Casiotron , the company primarily innovated in digital quartz technology . G-Shock watches , the F-91W , integrated calculators… Casio had established itself with its modern, durable, and affordable approach. The arrival of the EFK-100 series therefore marks a major shift.
Focus on the Edifice EFK-100: complete technical specifications
The concept: affordable sporty-chic design
The EFK-100 collection continues the Edifice line, offering a sporty watch with a sharp silhouette, drawing inspiration from the world of automobiles. Features include brushed steel, carbon fiber, and a mechanical movement. Put that way, you might think you're at a race car.
The variations of the EFK-100
The first of the new models is the EFK-100D , offered with three different dials: silver-white, blue, and green. The dial has undergone an electroforming process that replicates the effect of carbon fiber. With its 39mm diameter and 12.5mm thick stainless steel case and its metal bracelet alternating polished and brushed surfaces, this watch strikes a balance. Its launch price of €279 makes it particularly accessible for those entering the mechanical watch market.
A step above, the EFK-100CD stands out with its genuine forged carbon dial. This material, directly derived from the world of racing, adds texture and a technical look. The case retains the dimensions of the base model, but the overall design gains character. Here again, the steel bracelet completes the look, and the watch is priced at €299, a price point that confirms Casio's commitment to offering automatic watches with a price-to-performance ratio that is hard to beat.
Finally, the EFK-100XPB is the sportiest model in the range. Here, Casio has chosen forged carbon not only for the dial but also for the case. The whole is completed by a urethane strap, which reinforces its sporty look. Larger with its 40 mm diameter and 45 mm lug-to-lug measurement, this version is clearly aimed at those seeking a luxurious sporty design. More exclusive and limited, it is also positioned at a higher price point, around €449.
Common characteristics
Regardless of the model, Casio has chosen to rely on the same technical base: the NH35 automatic caliber, produced by TMI (Seiko). This is a tried-and-tested movement, appreciated for its robustness and ease of maintenance. It offers approximately 41 hours of power reserve and a frequency of 21,600 vibrations per hour, all supported by 24 jewels.
All versions of the EFK-100 feature a transparent case back, a detail that will appeal to those new to mechanical watchmaking. The sapphire crystal, ensuring scratch resistance, and the 100-meter water resistance guarantee versatile use. Casio has also paid close attention to legibility: skeletonized hands, luminescent applied hour markers, and a discreet date window at six o'clock.
Whether in steel or urethane, each strap contributes to a sporty and modern aesthetic, true to the Edifice spirit. By bringing these elements together, Casio has succeeded in its goal: to offer a versatile, attractive, and above all, affordable first mechanical collection.
Conclusion
Casio has taken a symbolic step with the Edifice EFK-100 : entering the world of mechanical watches. Combining meticulous finishing, high-end materials (forged carbon, sapphire), a sport-inspired design, and above all, a reliable and affordable automatic movement, these models represent an ideal offering in the accessible automatic segment. Price, style, and durability make the EFK-100 a true success for Casio, in our humble opinion.
