My Buying Guides on Eco Drive C690 Battery
When I first started looking for a replacement battery for my Eco Drive C690 watch, I realized that choosing the right one is crucial for maintaining the watch’s performance. Here’s what I learned through my experience that might help you pick the best Eco Drive C690 battery.
Understanding the Eco Drive C690 Battery
The Eco Drive C690 is a solar-powered watch, which means it doesn’t use a traditional disposable battery. Instead, it has a rechargeable cell that stores energy from light. When I was shopping, I learned that the battery is often referred to as a “secondary battery” or “rechargeable cell,” and it’s different from standard watch batteries.
Why Replacement Might Be Needed
Even though Eco Drive watches are designed to last for years without battery replacement, I found that after many years of use, the rechargeable cell can lose its ability to hold a charge. If your watch isn’t running properly or the power reserve seems shorter, it might be time to replace the battery.
Choosing the Right Replacement Battery
When I looked for a replacement, I found that the Eco Drive C690 typically uses a rechargeable lithium-ion battery, often labeled as CTL1616 or similar. It’s important to get the exact type recommended for your model to avoid compatibility issues. I recommend checking your watch’s manual or consulting a professional to confirm the correct battery type.
Where to Buy the Eco Drive C690 Battery
I found several options to buy replacement batteries:
- Authorized Seiko or Citizen dealers
- Specialized watch repair shops
- Reputable online stores that sell watch batteries
I always made sure to buy from trusted sources to avoid counterfeit or low-quality batteries, which can harm my watch.
DIY Replacement vs Professional Service
While some batteries can be replaced at home, I chose to have a professional watchmaker replace mine. The process requires carefully opening the watch case without damaging the seals that keep it water-resistant. Unless you have experience and the right tools, I suggest professional replacement to ensure your watch stays protected.
Maintaining Your Eco Drive Battery
To keep my Eco Drive battery healthy, I make sure to expose my watch regularly to natural or artificial light. Avoiding long periods of darkness helps maintain the battery’s charge capacity. Also, I avoid extreme temperatures and moisture to prolong battery life.
Final Thoughts
Replacing the Eco Drive C690 battery is not as straightforward as swapping a regular battery, but with the right information and care, it’s entirely doable. My advice: verify the exact battery type, buy from reliable sources, and consider professional installation to keep your watch running smoothly for years to come.
