Introduction
Owning a Citizen C690-Q01148 Eco-Drive watch means enjoying a blend of style and cutting-edge technology. This timepiece, part of the Attesa collection, uses light to power its analog and digital displays, eliminating the need for traditional batteries.
Understanding the Citizen C690-Q01148
The Citizen C690-Q01148 is a sophisticated watch from the Attesa line, featuring an Eco-Drive movement. Unlike quartz watches, it converts light into energy, stored in a rechargeable capacitor.
With a titanium case and a 34.4mm diameter, it combines durability with elegance. Its dual analog-digital display supports functions like time, date, alarms, and chronograph, making it a versatile choice for watch enthusiasts.
Why Replace the Capacitor?
Eco-Drive watches are built to last, but their capacitors typically hold a charge for 10-15 years. Over time, the capacitor may fail to retain energy, causing the watch to stop or display erratic behavior, such as a jumping second hand or fading digital display. Replacing the capacitor restores the watch’s ability to store light-generated energy, ensuring reliable performance.
Identifying the Correct Capacitor
For the Citizen C690-Q01148, the correct capacitor is the 295-44 (MT1620). Using the wrong capacitor can damage the watch’s movement. To confirm, check the movement number (C690) on the case back or consult Citizen’s technical guides. Authorized suppliers or watch repair specialists can provide the exact part for your watch.
Tools Needed for Replacement
To replace the capacitor, gather these tools:
- Small screwdriver or watch case opener
- Sim removal tool or precision tweezers
- Citizen 295-44 (MT1620) capacitor
- Soft cloth for cleaning
- Watch press (for press-fit case backs)
Having the right tools ensures a smooth process and prevents damage to your watch.
Step-by-Step Guide to Citizen C690-Q01148 Battery Replacement
Step 1: Prepare Your Workspace
Start by setting up a clean, well-lit workspace. Place a soft cloth on the surface to protect the watch from scratches. Remove the watch band or links to access the case back easily. This step ensures you have clear access to the watch’s internal components without risking damage.
Step 2: Open the Case Back
Check if your watch has a screwed or press-fit case back. For a screwed case back, use a watch case opener to unscrew it gently. For a press-fit case back, carefully use a watch press or a case knife to pry it open. Handle the gasket with care to maintain water resistance.
Step 3: Locate and Remove the Old Capacitor
Inside the watch, locate the capacitor—a small, round component with a connector. Use a sim removal tool or precision tweezers to gently pry it out. Take care not to damage the connector or surrounding movement. Note the capacitor’s orientation, especially the positive side, for proper installation of the new one.
Step 4: Install the New Capacitor
Take the new 295-44 (MT1620) capacitor and verify the positive side (marked with a “+”). Carefully insert it into the slot, ensuring the connector aligns correctly. Press it gently to secure it in place. Proper alignment is critical to avoid damaging the watch’s movement or affecting its performance.
Step 5: Close the Case Back
For a screwed case back, screw it back on carefully, ensuring it’s tight but not over-torqued. For a press-fit case back, use a watch press to secure it, ensuring the gasket is properly seated to maintain water resistance. A secure case back protects the watch from dust and moisture.
Step 6: Perform the All-Reset Procedure
After replacing the capacitor, reset the watch to restore functionality. Pull the crown to the setting position. Press and hold the top right (A) and bottom right (B) buttons simultaneously until the hands spin or the display blinks, indicating a reset. Release the buttons, push the crown back, and set the time and date.
Charging Your Watch After Replacement
New capacitors are not pre-charged. Place your watch under direct sunlight or a bright artificial light (e.g., 3000 LUX fluorescent light) for 5-10 hours. Pulling the crown out during charging can reduce charging time. Ensure the watch is fully charged before regular use to avoid performance issues.
Troubleshooting Common Issues
If your watch doesn’t work after capacitor replacement, try these steps:
- Verify Capacitor Installation: Ensure the capacitor is correctly seated and the connector is secure.
- Repeat the All-Reset: Perform the reset procedure again, following the exact steps.
- Check Charging: Confirm the watch has been exposed to sufficient light.
- Consult a Professional: If issues persist, contact a certified watchmaker or Citizen’s service center.
When to Seek Professional Help
While DIY replacement is possible, certain situations call for professional assistance. If you’re uncomfortable opening the watch, lack the proper tools, or suspect additional issues (e.g., movement damage), a certified watchmaker can ensure a safe and accurate repair. Citizen’s authorized service centers offer reliable repairs with genuine parts.
Maintaining Your Citizen C690-Q01148
To prolong your watch’s life, follow these maintenance tips:
- Regular Light Exposure: Keep the watch exposed to light to maintain capacitor health.
- Avoid Extreme Conditions: Protect the watch from excessive heat, moisture, or magnetic fields.
- Periodic Servicing: Have the watch serviced every 5-7 years to check lubrication and seals.
- Clean Gently: Use a soft cloth to clean the watch, avoiding harsh chemicals.
