EFK-110D-1AJF
The EDIFICE EFK-110 brings a Japanese automatic mechanical movement to a compact 38 mm case. An approximately 42-hour power reserve, sapphire glass and 10-bar water resistance make it suitable for daily wear. A transparent case back reveals the movement in operation. The electroformed dial adds texture, with raised indexes and a sharply defined bezel giving the face a sporty appearance. Alternating hairline and polished finishes on the stainless steel bracelet add depth to the exterior.
