Casio Edifice EQS-940DB-1AVUDF Black Dial Chronograph Watch

The Casio Edifice EQS-940DB-1AVUDF is a men's solar chronograph watch with a 45 mm stainless steel case, a black dial and a silver stainless steel band. It suits anyone who wants a single timepiece for timing, travel and everyday wear, and it runs on light rather than a replaceable battery.

The bezel is black ion-plated, giving the round case a darker rim above the steel. Mineral glass covers the dial. A quartz movement runs the hands, and a battery level indicator shows how much charge is left, so you know when to leave the Casio Edifice solar chronograph watch in daylight for a while. World time reads the hour in other zones, 100 metres of water resistance covers rain, splashes and swimming, and a date window keeps the day of the month within sight.

Key features and benefits of the Casio Edifice EQS-940DB-1AVUDF

• Solar power: The watch draws energy from light, so it keeps running without a battery swap. That means no booking in a battery change and no gap in timekeeping.
• Chronograph: A stopwatch function times intervals alongside the normal time display. You can time a run, a meeting or a recipe without reaching for your phone.
• World time: The watch can show the time in other time zones. It is useful when you travel, or when you work with people in another country and need their working hours.
• Battery level indicator: A display element shows how much charge is left. When it dips, a few hours of daylight or lamplight tops it back up.
• Mineral glass: Mineral glass is a hard, scratch-resistant crystal that protects the dial. It keeps the face clear through daily wear and wipes clean with a soft cloth.
• 100 metres water resistance: The case is rated to 100 metres, which covers splashes, rain and swimming. It is not built for diving or high-pressure water sports.
• 45 mm round case: The stainless steel case measures 45 mm across in a round shape. That gives a bold presence on the wrist while still tucking under most sleeves.
• Stainless steel band: The bracelet is stainless steel in a silver finish that matches the case. Steel resists corrosion and keeps its shape through daily wear.
• Black ion-plated bezel: The bezel is finished in black ion plating for a darker ring around the dial. The plating is chosen for its scratch resistance, so the rim keeps its look.
• Date display: A date window shows the day of the month. You get the date at a glance without checking another device.
• Quartz movement: Quartz timing uses a vibrating crystal to regulate the hands. It is accurate and needs very little attention beyond keeping the charge topped up.

Who the Casio Edifice solar chronograph watch is for

This Casio Edifice watch is aimed at men who want one watch that covers work, travel and weekends. The 45 mm steel case and black dial read as a dressy piece with a suit, while the chronograph, world time and 100 metre rating take it well beyond the office. It also suits anyone who would rather not think about battery changes.

• Wearing to the office or to meetings where a steel bracelet and black dial fit the dress code.
• Travelling across time zones, with world time giving a second zone at a glance.
• Swimming, or days outdoors where rain and splashes are part of the plan.
• Timing intervals, whether that is a training session, a commute or a recipe.
• Daily wear for people who prefer a low-maintenance watch.

Less suitable if: you dive or take part in high-pressure water sports, because the 100 metre rating covers swimming and splashes rather than diving.

Using and caring for the Casio Edifice EQS-940DB-1AVUDF

Solar watches stay charged as long as they see light, so a spell on a windowsill or under a lamp now and then keeps the battery level indicator healthy. The stainless steel case and band wipe clean with a soft, dry cloth, and the mineral glass takes a damp cloth when it picks up smudges. Press the crown fully in before the watch goes near water.

• Store the watch where light reaches it rather than in a closed drawer, so the charge holds.
• Wipe the bracelet after wear to lift sweat and dust from between the links.
• Keep the watch away from strong chemicals and extreme heat, which can mark the ion-plated bezel.
• Rinse and dry the case after swimming in salt water, then check the crown is pushed in.
• Use a soft cloth on the mineral glass rather than a rough one, to avoid fine marks.

How to choose a solar chronograph watch

Four things matter most in a watch like this. Movement comes first: a solar quartz module such as the one in the Casio Edifice EQS-940DB-1AVUDF removes battery changes but needs regular light. Case size is next, and this model measures 45 mm across, a bold diameter that sits well on medium and larger wrists. Check water resistance too, since 100 metres here means swimming is fine while diving is not. Then look at the extras you will actually use; this watch carries a chronograph, world time, a date window and a battery level indicator.
