How to change the battery of a quartz watch?

The power source of the quartz watch is the battery. Usually, the battery life of the quartz watch is 2-3 years. Once the time is not accurate, it is likely that the battery power is insufficient. Replacing the battery in a quartz watch is a relatively simple process that you can do at home with the right tools and care. Quartz watch manufacturers share step-by-step guides on how to replace quartz watch batteries:

Tools you need:

1. New watch battery (make sure it is the right type and size for your watch).
2. Watchmaker’s screwdriver set or watch back removal tool.
3. Tweezers (non-magnetic if possible).
4. Clean, lint-free cloth or watchmaker's gloves to avoid fingerprints.
5. Soft surface or pad used to protect the dial.

Steps to replace the battery:

1. Prepare your workspace

Work in a well-lit and clean area, free from dust and debris.
Place a soft surface or watch mat in the work area to protect the watch surface.

2. Identify the type of the case back

Some watches have screw-down case backs that require special tools to open, while others have snap-off case backs.
Determine what type of case back your watch has before proceeding.

3. Open the back of the watch

A. For the snap-on case back:
Use a case back removal tool or cover knife to carefully pry off the case back.
Insert the tool into the small gap between the watch back and the case.
Apply gentle pressure while rotating the tool to pop off the back cover.

B. For screw-in case backs:
Use the appropriate size screwdriver from the kit to remove the screws on the back cover.
Turn counterclockwise to remove the screw.
Carefully remove the back cover.

4. Find the battery

After opening the back cover, locate the battery inside the watch. It is usually held in place by small clips or brackets.

5. Remove the old battery

Use non-magnetic tweezers to carefully remove the old battery from its holder. Note the orientation of the battery, noting which side is facing up.

6. Insert new battery

Place the new battery in the same orientation as the old battery. Make sure it fits securely in the bracket.

7. Turn off the watch

If your watch has a snap-off back, carefully press it back into place until it folds.
If it has a screw-down back, use a screwdriver to retighten the screws.

8. Test the watch

Press the crown (the small knob on the side of the watch) to restart the watch.
Check to make sure the watch is operating properly and the hands are moving smoothly.

9. Replace the gasket (if applicable)

If your watch has a rubber or plastic gasket inside the case back, make sure it is clean and in good condition before resealing the watch.

10. Clean your watch

Use a clean, lint-free cloth or watchmaker's gloves to clean the outside of your watch to remove any fingerprints or smudges.

very simple! You have successfully replaced the battery in your quartz watch. If you are unwilling to do this yourself or encounter any difficulties, consider taking your watch to a professional watchmaker or jeweler for battery replacement and maintenance.
