3. Setup and Installation

Replacing a watch capacitor requires precision and specialized tools. It is highly recommended that installation be performed by a qualified watchmaker or a professional with experience in watch repair to avoid damage to the watch or the new capacitor.

General Installation Steps (for professional reference):

1. Carefully open the watch case back using appropriate tools.
2. Locate the existing capacitor. Note its orientation and connection points.
3. Gently remove the old capacitor, taking care not to damage surrounding components.
4. Insert the new MT920 capacitor, ensuring correct polarity and secure connection.
5. Carefully close and seal the watch case back, ensuring water resistance (if applicable) is maintained.

4. Operating Instructions

After installation, the new capacitor will need to be charged. Eco-Drive watches are powered by light, which is converted into electrical energy and stored in the capacitor.

Initial Charging:

• Place the watch in a location where it can receive direct light, such as near a window with sunlight or under a bright lamp.
• Avoid extreme heat, which can damage the watch.
• Allow the watch to charge for several hours, or even a full day, to ensure the capacitor reaches a sufficient charge level. The second hand should begin moving normally once enough charge is accumulated.

5. Maintenance

To ensure the longevity and optimal performance of your Citizen Eco-Drive watch and its new capacitor, follow these maintenance guidelines:

• Regular Light Exposure: Ensure your watch is regularly exposed to light. Do not store it in a dark place for extended periods.
• Avoid Extreme Temperatures: Protect your watch from extreme hot or cold temperatures, which can affect battery life and watch components.
• Cleaning: Keep the watch clean, especially the dial, to allow maximum light absorption.

6. Troubleshooting

If your watch does not function correctly after capacitor replacement, consider the following:

• Watch Not Running: Ensure the watch has been adequately charged after installation. Place it under strong light for an extended period.
• Intermittent Operation: This could indicate insufficient charge or a loose connection. Re-expose to light or have the installation checked by a professional.
• Incorrect Movement: Double-check that the capacitor is compatible with your specific watch movement number. Refer to Section 2.

If issues persist, it is advisable to consult a professional watch repair service.
