How to change the battery of the watch?

The battery replacement method of the watch is as follows:

Tools/raw materials: watches, fixers, screwdrivers, watch button cell, tools for fixing watches.

1. There are two kinds of back covers of watches, one is to open them by rotating and the other is to pry them open.

2. Rotating the open back cover requires two tools, one is to fix the watch, and the other tool is stuck in the card slot to select the watch cover.

You should knock on the watch cover with a screwdriver thin enough. Before prying it open, pull out the knob to make the watch in a state of no electricity. Although the battery is dead, there will still be a weak current flowing. When you pry it open, you should use force slowly and don't worry.

4. After opening the lid, slowly pull out the battery with a screwdriver, then put the new button cell in, and wipe off the dust by the way.

5. When replacing the back cover, press the back cover up slowly, and then press it hard along the edge of the back cover. When you hear a crisp sound, it means that the watch cover has been installed.
