Wrist watch CASIO EFR-556DB-2AVUEF – men's quartz, stainless steel case, 48.7×12.6×53.5 mm, SR920SW battery

CASIO EFR-556DB-2AVUEF is a men’s wrist watch with quartz movement housed in a stainless steel case with a silver finish. The case measures 48.7 × 12.6 × 53.5 mm, combining a substantial presence on the wrist with a slim profile. The watch is powered by an SR920SW battery with an approximate three-year life and features a multi-layered dial, 1-second stopwatch function, date display and 100-meter water resistance for everyday reliability.

Advantages

The stainless steel case provides corrosion resistance and a stable structure that protects the movement. The multi-layered dial improves legibility and gives clear separation between time markers and subdials. A 1-second chronograph and durable quartz movement deliver precise time measurement. With 100-meter water resistance and a long-life SR920SW cell, the watch is designed for regular daily use without frequent maintenance.

Suitable for

• Everyday office wear and business environments

Usage recommendations

For reliable operation, replace the SR920SW battery when the watch shows signs of reduced accuracy or when functions become intermittent. Clean the stainless steel case and bracelet periodically with a soft cloth and mild detergent solution, then rinse and dry thoroughly. For extended water exposure or post-impact inspection, have seals and water resistance checked by an authorized service center.
