  • Hold the case firmly, and insert the blade of the case knife into the indentation.
  • Apply gentle, steady pressure to pry the back open. Avoid forcing the blade too deeply, as this can damage internal components.
  • Once the back begins to lift, gently work the blade around the perimeter to release the cover fully.
  • Carefully remove the back and set it aside on a clean surface.

Throughout this process, avoid touching the interior mechanisms or the battery with bare hands, as oils and moisture can affect the watch’s performance.

Techniques for Unscrewing Screw-Back Cases

Some Timex models have screw-back cases featuring notches or grooves around the edge that require specific unscrewing techniques.

  • Secure the watch in a watch holder or between soft cloths to prevent slipping.
  • Inspect the back for notches that will accommodate the pins of a case wrench.
  • Adjust the pins on the case wrench to match the spacing of the notches.
  • Place the wrench pins into the notches and turn counterclockwise slowly.
  • If resistance is high, apply steady pressure and ensure the pins are properly seated.
  • Once loosened, unscrew the back by hand and remove it carefully.
  • For screw-down backs without notches, use a rubber friction ball by pressing it firmly against the back and turning counterclockwise.

Avoid using excessive force or inappropriate tools like knives, as this can cause deformation or scratches.

Precautions and Tips When Handling Watch Backs

Working with watch backs requires a cautious approach to maintain the integrity of the timepiece.

  • Always work in a clean, dust-free environment to prevent contamination of internal parts.
  • Use non-magnetic tools to avoid interference with watch mechanisms.
