Replacing Watch Batteries

If you have an inexpensive watch and you want to replace the battery yourself, it's very easy to do.

First, you will need to have a new battery ready to put in your watch. Buy the proper battery for your make/model of watch.

Next, flip your watch over and look at the back. There will be a small tab or concave area on the back of the watch, slip a small knife in the area and gently slide to the right or left (your choice). Try not to use the point of the knife, use the flat edge of the knife to raise up the watch back.

Do not touch any other parts within the back of the watch or you may render certain functions useless. If you have a diving watch, they must be pressurized and you can not change the battery yourself without rendering the watch totally useless.

There may be a rubber gasket that falls out when you take off the back case, this is to help your watch stay water resistant. Then, carefully pop the battery out and put the new battery that you purchased into the watch.

Put the gasket in place (if there was one) and put the metal cover back on your watch. Viola! You have changed a watch battery. Make sure that opening the back of your watch won't invalidate your warranty for your watch. If it will, best to take your watch to your neighborhood jeweler who can put a new battery in your watch usually rather quickly.
