The Casio Edifice EFK-100 Series delivers clean, sporty sophistication with mechanical muscle beneath the surface. Refined and compact, this automatic lineup offers modern watchmaking in a timeless silhouette — equally at home in a business setting or on weekend rotation.
Available in three dial variants — the EFK-100CD-1A with a carbon-pattern black dial, the EFK-100D-7A with a brushed silver dial, and the EFK-100D-2A with a bold sunburst blue dial — each features applied indices, luminous sword-style hands, and a framed date window at 3 o’clock. The case measures a compact 39mm wide, with a 43.5mm lug-to-lug and 12.5mm thickness, hitting the sweet spot for all-day comfort and versatility.
Inside is the dependable Seiko NH35A automatic movement, delivering reliable mechanical performance with hand-winding, hacking, and a 41-hour power reserve. With 100 meters of water resistance, a screw-down caseback, sapphire crystal, and a solid steel bracelet, the EFK-100 Series is Casio Edifice at its most refined — and now fully automatic.

Casio is a brand name most people are familiar with. Founded in 1946 in Japan as Kashio Seisakujo and reestablished as Casio Computer Co., Ltd. in 1957 - they’ve made everything from the world’s first all-electric calculator to synthesizers, cameras, and more. Of course, they are also famous for their watches, which include G-Shock, Pro Trek, Edifice, and other tech-forward brands. The Casio Vintage line, as the name suggests, celebrates their earliest digital timepieces. Always fun and irreverent, these fashionable watches are affordable and a great addition to one’s watch box.
