Casio Edifice EFR-571DC-2AVUDF Black Ion-Plated Chronograph Watch

The Casio Edifice EFR-571DC-2AVUDF is a men's chronograph watch with a black ion-plated stainless steel case and band. It suits men who want a bold analog watch for everyday wear, formal outfits and short timing tasks. The model pairs a retrograde chronograph layout with a date display and 100-meter water resistance.

The watch uses stainless steel for both the case and the band, with black ion plating, a dark finish applied to the metal. Mineral glass covers the dial, and a screw lock back seals the case. The one-touch 3-fold clasp opens and closes without fuss, while the analog display sets three hands alongside three dials for stopwatch minutes, stopwatch seconds and 24-hour time. A 1-second stopwatch runs to 9 minutes and 59 seconds, and the date display keeps the calendar close at hand. Casio rates timekeeping at ±20 seconds per month and battery life at about three years on an SR920SW cell.

Key features and benefits of the Casio Edifice EFR-571DC-2AVUDF

• Retrograde chronograph design: The dial uses a retrograde chronograph layout, where a timing hand travels an arc and snaps back to the start. That gives the timing display a distinctive look and separates it from a standard three-hand face.
• 1-second stopwatch: The stopwatch counts in one-second steps and measures up to 9 minutes and 59 seconds. That range suits short tasks such as timing a lap, a cooking step or a brief workout interval.
• 100-meter water resistance: The watch is rated to 100 meters, which covers swimming and snorkelling. Keep the buttons untouched while underwater so the seals are not stressed.
• Date display: A date display shows the current date on the dial. It saves you reaching for a phone when you need to check the day of the month.
• Mineral glass: Mineral glass protects the dial and is made to resist scratches. It keeps the face clear during daily wear.
• Stainless steel case and band: Both the case and the band are stainless steel. That gives the watch metal strength, and the black ion plating adds a dark finish that works with casual and formal clothing.
• One-touch 3-fold clasp: The clasp folds in three parts and opens with a one-touch release. It makes the watch quicker to put on and take off while keeping the band closed.
• Screw lock back: A screw lock back closes the rear of the case with a threaded fitting. It helps keep the internal mechanism sealed during normal use.
• Accuracy of ±20 seconds per month: Casio rates the watch at ±20 seconds per month. That figure gives you a clear idea of how closely it should keep time over a month.
• Approx. 3-year battery life on SR920SW: The watch uses an SR920SW battery with an expected life of about three years. That keeps battery changes infrequent.
• Analog display with 3 hands and 3 dials: Hour, minute and second hands sit alongside three dials for stopwatch minutes, stopwatch seconds and 24-hour time. You can read the time and timing information at a glance.
• Case size and weight: The case measures 51 × 47.1 × 11.3 mm and the watch weighs 146 g. That gives it a substantial wrist presence with an 11.3 mm profile.

Who the Casio Edifice EFR-571DC-2AVUDF is for

The Casio Edifice EFR-571DC-2AVUDF is aimed at men who want an analog chronograph watch that looks bold and still handles daily routines. Its black ion-plated stainless steel build suits office days, evenings out and weekend wear, while the stopwatch and date display add practical value for people who like to time short activities or check the date quickly. The 100-meter water resistance also makes it a reasonable choice for swimming and snorkelling, provided the buttons are not pressed underwater.

• A man choosing one watch for office wear and casual weekends.
• Someone who wants a stopwatch for short intervals rather than long race timing.
• Swimmers and snorkellers who want date and timing on the wrist.
• A gift for a man who likes metal-band watches with a dark finish.

Less suitable if: you want a watch without chronograph functions, or you prefer a band that is not metal.

Using and caring for the Casio Edifice EFR-571DC-2AVUDF

The black ion plating on the case and band is a finish, so treat it as you would any coated metal: wipe off sweat and dirt after wear, and keep the watch away from harsh cleaners. The 100-meter water resistance supports swimming and snorkelling, but the pushers should stay untouched while the watch is underwater. Have the battery changed when the watch begins losing time; Casio gives an approximate three-year life on an SR920SW cell.

• Wipe the case and band with a soft, damp cloth, then dry with a soft cloth.
• Store the watch in a dry place when you are not wearing it.
• Check the one-touch 3-fold clasp for secure closure before swimming.
• Do not press the buttons underwater.
• Replace the SR920SW battery when timekeeping drops, around the three-year mark.
