Introduction

Although the Ecodrive watches made by Citizen contain a rechargeable battery, after a long period of usage the battery is no longer able to hold a charge. When that occurs, it would be less expensive to replace the battery instead of buying a new watch. This guide demonstrate how to properly perform that on a Citizen Ecodrive watch.

Before doing any repairs it might be a good idea to do these:

1. Place the watch to bright sunshine for one full day the dial facing straight to the sun.

2. After the sun treatment pull the knop fully out and keep it that way for 30 seconds (or more).

3. Press the knop back in and wait for 10 seconds.

4. If the watch now works normally, you saved the battery price and your fixing work…

5. If not, you unfortunately have to do as instructed here.

Good luck!
