How to Change a Watch Battery

Imagine this scenario: You’re sitting on your couch, minding your own business, when the second hand stops ticking. There are two possible reasons that this happened: Either time has stopped altogether, or your watch battery is dead. Some scientists from UC Berkeley predict that time could end within the next three to four billion years. Most agree that it’s very unlikely to happen during our lifetime.

With that in mind, you can safely conclude that your watch’s battery has died. You know what that means: You need to change your watch battery for a new one. You might wonder, how to change a watch battery?

How to Change a Watch Battery in 10 Simple Steps

Step 1: Remove the back cover. 

There are generally three types of back covers: ones that unscrew themselves, ones that require a small screwdriver, and ones that must be gently pried loose.

Step 2: Remove the gasket. 

If you notice a rubber ring underneath the back cover, this is the gasket. Set it aside before taking out the battery. Note: If it’s dirty, you should clean it, too.

Step 3: Find the watch battery. 

Most watch batteries are of the button-cell variety. It’ll usually be a shiny metallic color, with a diameter somewhere between 6 and 9.5 millimeters.

Step 4: Extract the watch battery. 

Now for the big moment! Once you’ve located the watch’s battery, it’s time to determine what’s holding it in place. Some are restrained with a cover and screw, others with a spring clip, and still others are more loosely installed. Make sure that you use the correct tool for the job. Warning: We recommend using plastic tools, rather than metal ones, to avoid an electrical shock.

Step 5: Identify the watch battery. 

Notice the 3- or 4-digit number on the back of the casing. This will tell you exactly which model it is.

Step 6: Buy the watch battery replacement. 

You can purchase replacement watch batteries in most jewelry stores, electronics stores, drug stores, or hardware stores. You’ll also find plenty of them on our Battery Depot website! Refer to your defunct battery’s identification number to ensure that you’re getting the rig
ht one for your timepiece.

Perform Step 4 in reverse.

Step 8: Make sure that it’s working.
