Maintenance
Water Resistance
Your Casio WSC-1250H-3AVCF watch is water resistant to 100 meters (330 feet). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. It is also suitable for swimming and snorkeling. However, it is not recommended for scuba diving. Avoid operating buttons while the watch is wet or submerged to prevent water ingress.
Battery Replacement
The watch is powered by one CR1220 battery, with an approximate life of 3 years. When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance.

Cleaning
To clean your watch, wipe it with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner or benzine, as they may damage the resin components.
Troubleshooting
- Display is dim or blank: This usually indicates a low battery. Replace the CR1220 battery.
- Time is incorrect: Re-adjust the time and date settings as described in the "Initial Setup" section. Ensure the correct home city is selected.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though this model typically doesn't have a button lock). If wet, dry the watch thoroughly. If the issue persists, a battery replacement or professional inspection may be required.
- Water inside the watch: Immediately take the watch to a qualified service center. Do not attempt to dry it yourself, as this can cause further damage.
