To open the back cover of an electronic watch to replace the battery, the method varies depending on the model and design of the watch. In general, you can follow these steps:
1.Confirm the type of watch: First, you'll need to determine what type of watch your watch is, such as a screw-on back, press-fit back, or a special tool to open the back.
2.Screw-up back cover:

Try using your fingers or fingernails to find a bump between the sides.
Using moderate force, gently push upwards along the edge of the watch or bounce up on the back cover until it comes loose.
Gently remove the press-fit back cover and remove the battery.

Some watches require special tools to open the back cover.
