4. Maintenance

4.1 Cleaning

Wipe the watch regularly with a soft, dry cloth to remove dirt and sweat. For stubborn grime, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.

4.2 Water Resistance Care

• Do not operate buttons underwater.
• Avoid exposing the watch to hot water or steam (e.g., hot showers, saunas), as this can damage the waterproof seals.
• If the watch is exposed to saltwater, rinse it with fresh water and dry thoroughly.

4.3 Battery Replacement

The watch uses two types of batteries: CR2016 for the digital functions and SR626SW for the analog movement. When the display dims or the watch stops functioning, it's time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.

5. Troubleshooting

• Digital Display is Dim or Blank: The battery may be low or depleted. Refer to Section 4.3 for battery replacement.
• Analog Hands Not Moving: The SR626SW battery for the analog movement may be depleted. Refer to Section 4.3.
• Time is Inaccurate: Re-set the time following the instructions in Section 2.2. If the issue persists, the battery may be weak, or the watch may require servicing.
• Buttons Unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a stated feature for this model). If buttons are stuck, gently clean around them. If still unresponsive, professional inspection may be needed.
• Water Inside the Watch: Immediately take the watch to a professional for inspection and repair to prevent further damage.
