You Will Need

  • Watch with a snap back, hatch back, or screw back
  • Case holding vise
  • Case knife
  • Fine point tweezers
  • Plastic tweezers
  • Small screwdriver
  • Replacement battery or batteries
  • EWB-1 battery tester
  • Case wrench
  • Watch-closing hand press
  • Polishing cloth
  • Toothpick (optional)


  1. Step 1

    Open the band or remove

    Open the watchband or remove it. If the band is connected by a clasp, remove the spring-loaded pin that holds it together with a toothpick.

  2. Step 2

    Place in the vice

    Open the 2 sides of the case holding vise, place the watch in the middle, and slowly release and tighten the sides. The watch should be held snugly.

  3. If you have a specialized watch or waterproof watch, you should take it to a professional watch repair to prevent any damage to the timepiece.

  4. Step 3

    Remove the back

    Remove the back of the watch. Use a case knife to wedge under the back of a snap back and pop it up. Use a screw driver to remove a hatch back. Use a case wrench to remove a screw back by placing the tips in the back slots and twisting counterclockwise.

  5. Step 4

    Move the battery clip

    Move the battery clip out of the way with tweezers for a removable clip or a screwdriver for a screw clip or permanent clip.

  6. Step 5

    Remove battery and test

    Remove the battery and use a battery tester to check it. If the tester shows the battery isn't dead, then your watch needs repairs. If your watch has 2 batteries and one is "good," replace both batteries.

  7. Step 6

    Clean the battery compartment

    Remove any dirt and debris from the battery compartment with a pair of plastic tweezers or a cleaning cloth.

  8. Step 7

    Insert battery and battery clip

    Insert the new battery and snap the battery clip back on or screw the clip back into place.

  9. If your watch has a screw clip, you will need to use a pair of tweezers to hold the clip in place while you twist the screw back in.

  10. Step 8

    Close the watch

    Replace the watch back and secure with the screwdriver, case wrench, or a watch hand press.

  11. Step 9

    Clean the watch and replace hinge pin

    Clean the watch with a cleaning cloth. If you removed the hinge pin on the clasp, put the clasp back together and replace the pin.

  12. Step 10

    Reset the watch

    Reset the time on the watch and put it on. Now you'll have to come up with a new excuse for your tardiness!
