The Citizen C690-Q01148 battery replacement process is essential for maintaining the functionality of your Citizen Eco-Drive watch, particularly the ATTESA model with the C690 movement. Known for its solar-powered technology, the Citizen C690-Q01148 relies on a rechargeable capacitor (often referred to as a battery) to store energy. Over time, this capacitor may lose its ability to hold a charge, necessitating a replacement. This guide provides a detailed, step-by-step approach to the Citizen C690-Q01148 battery replacement, ensuring your watch continues to perform optimally. With clear instructions, practical tips, and expert insights, this article aims to make the process accessible to both beginners and seasoned watch enthusiasts.
Understanding the Citizen C690-Q01148 Eco-Drive Technology
Before diving into the Citizen C690-Q01148 battery replacement, it’s crucial to understand the technology behind this watch. The Citizen C690-Q01148 is part of the ATTESA series, featuring a Sepa Eco-Drive solar movement. Unlike traditional quartz watches that rely on disposable batteries, Eco-Drive watches use a rechargeable capacitor that converts light into energy. The C690 movement, specifically, powers a 1/100th-second chronograph and other advanced features, making it a sophisticated timepiece.
However, even with its advanced technology, the capacitor in the Citizen C690-Q01148 may degrade after years of use, leading to issues like the watch stopping or failing to hold a charge. This is where the Citizen C690-Q01148 battery replacement becomes necessary. The replacement process involves swapping out the old capacitor with a new one, such as the MT920 or CTL920F, which is compatible with the C690 movement.
Why Replace the Battery in Your Citizen C690-Q01148?
The Citizen C690-Q01148 battery replacement is not just about restoring functionality; it’s about preserving the longevity of your investment. Here are some reasons why you might need to replace the capacitor:
- Diminished Charge Capacity: Over time, the rechargeable capacitor may lose its ability to store energy, even when exposed to sufficient light.
- Watch Stopping or Losing Time: If your watch stops or loses time despite being exposed to light, it’s a sign that the Citizen C690-Q01148 battery replacement is overdue.
- Aging Technology: Capacitors typically last 7–10 years, depending on usage and light exposure. After this period, a replacement is often required to maintain performance.
By addressing these issues promptly, you can ensure your Citizen C690-Q01148 continues to function as a reliable and stylish timepiece.
Tools Required for Citizen C690-Q01148 Battery Replacement
To perform a Citizen C690-Q01148 battery replacement, you’ll need the right tools to avoid damaging the watch’s delicate components. Here’s a list of essential tools:
- Precision Screwdriver Set: For removing the case back screws.
- Watch Case Opener: To safely open the watch’s case back.
- Anti-Static Tweezers: To handle the capacitor without causing static damage.
- Replacement Capacitor (MT920 or CTL920F): Ensure it’s compatible with the C690 movement.
- Clean Cloth: To maintain a dust-free workspace.
- Magnifying Loupe: For precision work on small components.

Having these tools ready will make the Citizen C690-Q01148 battery replacement process smoother and safer.
Step-by-Step Guide to Citizen C690-Q01148 Battery Replacement
Step 1: Prepare Your Workspace
Before starting the Citizen C690-Q01148 battery replacement, set up a clean, well-lit workspace. Lay down a soft cloth to prevent scratches and ensure all tools are within reach. Working in a dust-free environment is critical to avoid debris entering the watch.
Step 2: Remove the Case Back
Using a precision screwdriver or watch case opener, carefully remove the case back of your Citizen C690-Q01148. Most models have a screw-down or snap-on case back. For screw-down cases, use the appropriate screwdriver to loosen the screws. For snap-on cases, gently pry open the back with a case opener, being cautious not to scratch the titanium case.
Step 3: Locate the Capacitor
Once the case back is removed, you’ll see the internal components of the C690 movement. The capacitor, typically a small, cylindrical component, is located near the movement’s center. For the Citizen C690-Q01148 battery replacement, identify the MT920 or CTL920F capacitor, which is specific to this model.
Step 4: Remove the Old Capacitor
Using anti-static tweezers, carefully remove the old capacitor. Note its orientation to ensure the new capacitor is installed correctly. Avoid touching other components to prevent damage to the movement. If the capacitor is secured with a clip or bracket, gently release it before removal.
Step 5: Install the New Capacitor
Insert the new MT920 or CTL920F capacitor in the same orientation as the old one. Ensure it’s securely seated and connected to the movement. The Citizen C690-Q01148 battery replacement requires precision, so double-check the connection to avoid loose fittings.
Step 6: Reassemble the Watch
Carefully place the case back onto the watch, ensuring it aligns properly. For screw-down cases, tighten the screws evenly to avoid damaging the threads. For snap-on cases, press the case back firmly until it clicks into place.
Step 7: Charge the Capacitor
After completing the Citizen C690-Q01148 battery replacement, expose the watch to bright light to charge the new capacitor. Citizen recommends 1–5 hours of direct sunlight or 3000 LUX fluorescent light at a distance of about 20 cm (8 inches) to fully charge the capacitor. This step is crucial to ensure the watch functions properly.
Step 8: Test the Watch
Once charged, test the watch to ensure all functions, including the chronograph and timekeeping, are working correctly. If the watch doesn’t start or exhibits issues, revisit the capacitor installation or consult a professional.
Tips for a Successful Citizen C690-Q01148 Battery Replacement
- Use Genuine Parts: Always use a genuine Citizen capacitor, such as the MT920 or CTL920F, to ensure compatibility and performance.
