5. Maintenance and Care

5.1 Cleaning Your Watch

Regular cleaning helps maintain the appearance and functionality of your watch. Wipe the watch case and band 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.

5.2 Water Resistance

Your G-Shock DW6900-1V is rated for 200-meter water resistance. This means it is suitable for recreational scuba diving. However, avoid operating buttons underwater, as this can compromise the water seal. After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it with a soft cloth.

5.3 Battery Replacement

The watch uses one LR44 battery (included). The battery life typically lasts for several years, but this can vary depending on usage of features like the backlight and alarm. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by an authorized Casio service center to ensure proper sealing and water resistance is maintained.

6. Troubleshooting

If you encounter issues with your watch, refer to the following common problems and solutions:

• Blank Display or Dim Display: This usually indicates a low battery. Replace the battery as described in Section 5.3.
• Incorrect Time/Date: Re-adjust the time and date settings as described in Section 3.2. Ensure the correct city code and DST setting are selected.
• Buttons Not Responding: Ensure the watch is not in a mode that locks button operations. If the issue persists, a full reset might be necessary (consult a service center).
• Water Inside Display: If condensation or water droplets appear inside the watch, stop using it immediately and take it to an authorized service center. This indicates a breach in the water resistance.
