You rely on your watch to keep the time, hardly giving it a thought until one day when it decides to stop running. More often than not, that means it's time to change the battery. Replacing a watch battery requires removing the back of the watch, called the case back, in order to remove the old battery and insert a new one. Returning the case back to its normal spot is an uncomplicated task that you can perform in a short amount of time.

Items you will need

  • Soft surface
  • Case back wrench
  • Small standard screwdriver
Step 1

Set the watch face down on a soft surface, such as a computer mouse pad or a cloth. This protects the watch face from being scratched.

Step 2

Place the case back on the watch. Some watches will have a rubber O-ring or gasket. If yours does, place this in position before placing the case back on.

Step 3

Align the indent on the case back with the indent on the side of the watch and press on the case back gently with your thumbs until you hear a click. The case back is now in place.

Step 4

Use a small standard screwdriver or a case back wrench, available at many hardware or watch repair stores, to close a case back that has several slots on the back. Use the screwdriver or the metal tips on the case back wrench to turn the slots on the case back in a counterclockwise direction. When all of the slots have been turned, the case back is in place.

Step 5

Set the watch, if necessary.
