Edifice Automatic EFK-110 Series 38mm Watch Collection

The Casio Edifice EFK-110D ships within 1-2 weeks.

The Casio Edifice EFK-110D is a proper second act that addresses the things people wanted, without touching what was already working. The original EFK-100D made a genuine case for Casio's entry into mechanical watchmaking: well-finished, well-sized, priced under $300, and powered by a dependable Japanese automatic. The EFK-110D takes that foundation and tightens it in every direction that counts. Smaller case, slimmer profile, shorter lug-to-lug, a new movement, and a date window that's moved from 6 o'clock to 3 o'clock.

The design language stays the same — electroformed textured dial, integrated H-link bracelet with polished and brushed surfaces, sharply defined bezel, hollowed hands — but the overall package wears noticeably better on the wrist than its predecessor. The stainless steel case comes in at 38mm across and 11.8mm thick with a 43mm lug-to-lug — down from 39mm, 12.5mm, and 43.5mm respectively on the EFK-100D. Those aren't dramatic numbers on paper, but a 0.7mm reduction brings the Edifice into range for wrists that found the original slightly too tall. The case finishing carries over with a combination of mirror-polished and hairline-brushed surfaces that gave the original its visual depth. The sapphire crystal sits above the dial with the same high-transparency AR-free clarity. 

The movement has also been changed. Where the EFK-100D ran on a Seiko Instruments NH35, the EFK-110D switches to the Miyota 8215 — a 21-jewel Japanese automatic operating at 21,600 bph with a 42-hour power reserve, manual-wind capability, and hacking seconds. The practical tradeoff versus the NH35 is unidirectional winding (the 8215 is a single-direction rotor). The whole movement remains visible through the screw-down exhibition caseback. Water resistance holds at 100 meters.
