Use a soft, dry cloth to wipe away fingerprints. For more thorough cleaning, use a damp cloth with mild soap, then rinse with fresh water and dry immediately.

Yes, the lugs are compatible with standard aftermarket watch straps if you prefer to change the look, though it is recommended to have a professional handle the spring-bar removal.

The EFR-539BK-1A2 features luminescent markers on the hands and dial indices, which provide visibility in low-light conditions after being charged by a light source.

Battery life varies based on usage of the chronograph features, but under normal conditions, the battery should provide several years of operation.

The battery may be depleted. Take the timepiece to an authorized service center for a battery replacement.

Refer to the user manual to perform a hand-alignment procedure, which allows you to manually reset the chronograph hands to the 12 o'clock position.
