4. Maintenance

Water Resistance:

Your Casio W-737H-1A2VCF watch is rated for 100-meter (10 BAR) water resistance. This means it is suitable for everyday use, showering, swimming, and snorkeling. However, it is not designed for scuba diving or high-impact water sports. Avoid operating buttons while the watch is wet or submerged to prevent water ingress.

Battery Life:

The watch is powered by a CR2025 lithium battery, providing an approximate battery life of 10 years under normal usage conditions. 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.

Care and Cleaning:

• Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture.
• For stubborn dirt, use a soft brush and mild soap solution, then rinse thoroughly with fresh water and dry completely.
• Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
• Do not use chemical cleaners or solvents, as they may damage the resin case and band.

5. Troubleshooting

Display is Blank or Dim:

• The battery may be low. Consider replacing the battery.
• Ensure the watch is not exposed to extreme cold, which can temporarily affect LCD performance.

Time is Incorrect:

• Re-set the time and date following the instructions in the 'Setting the Time and Date' section.
• Check if Daylight Saving Time (DST) is incorrectly set.

Buttons are Unresponsive:

• Ensure the watch is not wet when pressing buttons, as this can cause issues.
• A strong impact might have dislodged internal components. If the issue persists, seek professional service.

Alarm Does Not Sound:

• Verify that the daily alarm is activated in Alarm Mode. Look for the alarm indicator on the display.
• Check the battery level.
