Step-by-Step Procedure to Open a Snap-Off Timex Watch Back

Opening a snap-off case back requires careful handling to avoid scratching or damaging the watch.

  1. Place the watch face down on a soft cloth to protect the crystal.
  2. Locate the small indentation or lip on the edge of the case back.
  3. Insert the thin edge of the case knife or a suitable pry tool into the indentation.
  4. Apply gentle, steady pressure to lift the back away from the case; avoid using excessive force.
  5. Once lifted, carefully work the tool around the edge to fully remove the back.

Important Tips:

  • Do not insert the tool too deeply to prevent damage to internal components.
  • If the back is resistant, alternate prying gently around the edges instead of forcing one spot.

Step-by-Step Procedure to Open a Screw-Down Timex Watch Back

Screw-down backs provide a secure seal and require specific tools to unscrew.

  1. Place the watch face down on a soft surface to avoid scratching.
  2. Adjust the Jaxa wrench or case opener to fit the notches on the case back.
  3. Position the tool so that its pins align firmly with the notches.
  4. Turn the wrench counterclockwise with steady, moderate pressure to unscrew the back.
