Maintenance
Water Resistance
Your Casio AE-2000W-1AVCF watch is water resistant to 200 meters (660 feet). This means it is suitable for recreational scuba diving, but not for saturation diving. Avoid operating buttons while the watch is wet or submerged to prevent water ingress.
Battery Life
The watch is equipped with a 10-year battery. When the display becomes dim or the backlight weakens, it indicates that the battery is nearing the end of its life and should be replaced by a qualified technician to maintain water resistance.
Cleaning and Storage
- Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture.
- For resin bands, wash with water and mild soap, then rinse thoroughly and dry.
