Timex Watch Battery Replacement — How to Do It?

Replacing the battery of your Timex watch is easy. 

But before you can replace the battery in your Timex watch, you’ll need to have a few items on hand:

  • New watch battery in the correct size for your specific Timex model

You’ll need a new replacement watch battery that is the right size and model for your particular Timex watch.

As explained earlier, check the back of your watch for the model number, then use an online battery chart to find the battery size needed for your Timex watch model. 

Once you know the battery size, purchase the exact battery for your watch so it will fit properly.

  • Small screwdriver for opening the back

After purchasing the battery, get a small screwdriver made for watches to unscrew and open up your Timex watch case. 

This will help you to pop the back case off from your Timex watch to change the battery.

  • Tweezers for removing the old battery

Once the case is open, you’ll need a good pair of tweezers to carefully pluck out the old or dead battery from inside the Timex watch. 

Tweezers allow you to grip the tiny battery without touching it directly.

  • Clean cloth or tissue

After taking out the old/dead battery, get a soft lint-free cloth or tissue handy to wipe away any fingerprints or smudges from the watch face or interior parts when changing the battery. 

  • Eyeglasses if needed for magnification

If you have trouble seeing the small parts, it can be helpful to wear magnifying eyeglasses. 

This allows you to see the tiny battery compartment clearly so you can remove the old battery and insert the new one properly.
