Description
The Casio Edifice EFR-571DC-1AV (also referenced as EFR-571DC-1AVDF / EFR-571DC-1A) is a high-performance, Japanese-engineered quartz chronograph designed for men by Casio under the speed-and-intelligence-inspired Edifice line. Known among watch enthusiasts and racing fans by its series nicknames—the "Black Ion Plated Chronograph" or "Dark Stealth Chronograph"—this 47.1mm timepiece pairs a dark gray/black ion-plated stainless steel case with a multi-layered matte black dial, a screw-lock back plate, a date display at 3 o'clock, and a solid dark gray ion-plated stainless steel construction. Engineered for modern gentlemen who appreciate tactical motorsport aesthetics, stealth styling, and precise chronograph capabilities, it blends bold wrist presence with daily durability. The defining visual highlight of this EFR-571DC-1AV reference is its multi-dimensional black dial face set within a sleek, dark gray ion-plated case. Set beneath a protective mineral crystal, the dial features bold 3D hour markers with luminous accents, sporty sub-dials positioned for stopwatch functions, and a framed calendar date window at 3 o'clock. The monochrome dark stealth aesthetic delivers a powerful, high-contrast look while ensuring effortless legibility day or night. Beneath its stealthy exterior, the watch is driven by a high-accuracy Japanese Quartz Movement powered by an SR920SW battery, offering a reliable battery life of approximately 3 years with a timekeeping precision within ±20 seconds per month. The integrated 1-second chronograph features an extended measuring capacity of up to 9 hours, 59 minutes, and 59 seconds, complete with timing modes for elapsed time, split time, and 1st-2nd place finishes. The housing measures 47.1mm in case width (51.0mm lug-to-lug) with a profile thickness of 11.3mm and a total weight of 146 grams, offering a well-balanced, comfortable fit on the wrist. Dial protection is provided by a durable, scratch-resistant mineral crystal. Engineered for everyday durability and water activities, the stainless steel case incorporates a dark gray ion-plated finish, a screw-lock back plate, and a protected crown guard, achieving a certified 100-meter (10 bar / 330 ft) water resistance rating to protect against daily rain, splashes, showering, and swimming. The timepiece comes completed on an integrated dark gray ion-plated stainless steel link construction, secured by a solid one-touch 3-fold deployment clasp.
