By the end, you’ll be equipped with the information to handle this maintenance task efficiently and keep your Timex ticking like new.

Removing the Back Cover of Your Timex Watch

Before attempting to replace the battery, gaining access to the watch’s internal components is essential. Timex watches generally have two types of back covers: snap-off and screw-off. Identifying which type your watch has will determine the tools and method you need.

For snap-off backs, look for a small indentation or lip along the edge of the case back. This allows you to pry the cover open with a case knife or a thin, flat tool. Exercise caution to avoid scratching the case or injuring yourself. Insert the tool carefully into the indentation and gently twist or pry until the back pops off.

Screw-off backs are typically found on higher-end or water-resistant Timex models. These covers have several small notches or grooves spaced evenly around the perimeter. To remove a screw-off back, use a case wrench or adjustable watch opener designed to grip these notches securely. Turn the wrench counterclockwise to unscrew the back cover. If you do not have a watch case wrench, a rubber ball with a good grip can sometimes work by applying firm pressure and twisting.

Identifying and Removing the Old Battery

Once the back cover is removed, you will see the battery secured under a small metal clip or retainer. The battery is usually a small, round silver oxide cell.

Take note of the battery type and number inscribed on the battery surface. This information is crucial when purchasing a replacement. Common Timex watch batteries include types such as CR2016, CR2025, or SR626SW.

To remove the battery:

  • Use a pair of non-metallic tweezers or a plastic tool to avoid short-circuiting.
  • Carefully lift the metal clip or retainer holding the battery in place. Some retainers are spring-loaded and can be gently pushed aside.
  • Slide the battery out from under the clip.

Avoid touching other components inside the watch as they can be fragile or sensitive to static electricity.

Installing the New Battery

After removing the old battery, clean the battery compartment if there is any dust or debris. Use a soft brush or a can of compressed air to clear the area.

Insert the new battery with the correct polarity. Usually, the positive side (+) faces outward, but verify this based on the battery type and watch model. Ensure the battery sits flat and securely under the retainer or clip.

Gently press the metal clip back into place if it was moved or lifted. Confirm that the battery is firmly held and does not move around inside the compartment.

Replacing the Back Cover and Testing the Watch

Before sealing the watch, check that the watch is functioning properly by observing the second hand or digital display. If the watch does not start, double-check battery orientation and contact points.

To replace the back cover:

  • For snap-off backs:
  • Align the cover properly over the case.
  • Press down firmly with your thumbs or use a watch press tool to snap it back into place.
  • Ensure it is evenly sealed all around.
  • For screw-off backs:
  • Place the cover on the case, aligning the threads carefully.
  • Turn clockwise by hand initially to avoid cross-threading.
  • Use the case wrench to tighten securely but avoid over-tightening as this can damage the threads.
Back Cover Type Removal Tool Replacement Method Common Models
Snap-off Case knife or flat pry tool Press firmly to snap back on Basic Timex Weekender, Easy Reader
Screw-off Case wrench or rubber ball Turn clockwise to screw on Timex Ironman, Expedition

Once the back is securely in place, set the time and date as needed. Your Timex watch is now ready to wear with a fresh battery installed.

Identifying the Type of Timex Watch Battery Required

Before replacing the battery in your Timex watch, it is essential to determine the correct battery type. Using the wrong battery can damage the watch or result in inaccurate timekeeping.

  • Consult the Owner’s Manual: The manual typically specifies the battery model number.
  • Check the Back Case of the Watch: Some Timex watches have the battery type engraved or printed on the case back.
  • Inspect the Existing Battery: If accessible, remove the old battery and note the model number printed on it.
  • Use Online Resources: Timex’s official website and watch battery databases provide cross-reference guides based on your watch model.
Common Timex Battery Types Equivalent Battery Codes Typical Watch Models
