Wrist watch Casio EFR-552D-1AVUEF Male Quartz Stainless steel

The Casio EFR-552D-1AVUEF is a male quartz wrist watch with a solid stainless steel case and stainless steel bracelet. The watch features a durable mineral glass, a date and weekday display, a 10-minute stopwatch and a luminous Neo-display that provides long-term illumination after short exposure to light. It is water resistant to 10 bar (100 metres) and runs on a single SR927W battery with an approximate battery life of three years.

Advantages

Durable materials include a solid stainless steel case and stainless steel band together with scratch-resistant mineral glass. The screw-locked back protects the movement and allows straightforward battery replacement. A secure safety catch reduces the risk of the bracelet opening accidentally. The Neo-display improves readability in low light, and the watch maintains an accuracy of approximately ±20 seconds per month.

Suitable for

• Everyday wear and business-casual outfits
• Swimming and snorkelling (water resistance to 10 bar / 100 m)
• Users who need date and weekday indication

How to use

Set the time, date and weekday using the crown following the watch manual: pull the crown to the appropriate position and rotate until the correct values are shown. Use the stopwatch by starting, stopping and resetting with the designated pushers. The Neo-display charges by exposure to light; place the watch under a light source for a short time to restore luminescence. Replace the battery with a compatible SR927W cell; battery replacement and service are recommended at an authorised service centre to preserve water resistance and the screw-locked back seal.

Recommendations

Do not operate pushers underwater. After exposure to salt water, rinse the watch with fresh water and dry thoroughly. For guaranteed water resistance and correct resealing, have battery replacement and any repairs performed by an authorised service provider.
