Removing the Back Cover of Your Timex Expedition Watch

To access the battery compartment of your Timex Expedition watch, the back cover must be carefully removed. Depending on the specific model, the back cover may be a snap-on type or secured with screws. Using the correct method ensures the watch remains intact and avoids damage.

For snap-on backs, gently pry the cover open using a thin, flat tool such as a case knife or a small flathead screwdriver. Insert the tool in the small notch or gap along the edge of the back cover and carefully twist or lift it to pop the cover off. Avoid applying excessive force to prevent bending or scratching the case.

If your watch has a screw-back cover, locate the small screws around the edge of the back. Using a precision screwdriver set, unscrew each carefully and place them aside in a secure spot. Once all screws are removed, lift the back cover off gently. Be mindful of any gaskets or seals that maintain water resistance; these should be preserved and reinstalled properly.

Identifying and Removing the Old Battery

Once the back cover is removed, the internal components of the watch become accessible. The battery is typically housed under a small metal clip or retainer to hold it in place.

Before proceeding, ensure you are working in a clean, static-free environment. Use plastic tweezers or a non-metallic tool to avoid short-circuiting the battery or damaging the watch’s circuitry.

Locate the battery, which is usually a small, round silver cell. Note the battery model number, often printed on its surface, as this will be crucial for purchasing the correct replacement.

To remove the old battery:

  • Gently lift or slide the retaining clip if present.
  • Carefully extract the battery with tweezers.
  • Avoid touching other components or the watch’s movement.

Store the old battery safely for proper disposal according to local regulations.

Choosing the Correct Replacement Battery

Timex Expedition watches commonly use specific coin cell batteries, but the exact type depends on the model. Using the correct battery ensures proper function and longevity.

Below is a table outlining common Timex Expedition battery types and their specifications:

Battery Model Voltage Diameter (mm) Height (mm) Typical Usage
CR2016 3V 20.0 1.6 Basic digital models
CR2025 3V 20.0 2.5 Advanced digital/analog models
CR2032 3V 20.0 3.2 Most common Timex Expedition models

Always verify the battery number on the original cell to ensure compatibility. Additionally, purchase batteries from reputable sources to guarantee authenticity and performance.

Installing the New Battery Safely

When ready to install the new battery, handle it with clean hands or plastic tweezers to avoid contamination that can reduce battery life. Align the battery with the positive (+) side facing up, matching the orientation of the previous battery.

Place the battery into the compartment carefully, ensuring it sits flat and makes proper contact with the terminals. If there is a retaining clip, secure it gently without applying excessive pressure that could damage the battery or internal components.

Before closing the back cover, check the watch to confirm it powers on and functions correctly. If the watch does not start, double-check the battery orientation and contact points.

Reassembling the Watch and Maintaining Water Resistance

After confirming the watch operates with the new battery, carefully reinstall the back cover. If the watch has a gasket or rubber seal, inspect it for damage or dirt and clean or replace it if necessary to maintain water resistance.

For snap-on backs, press the cover firmly and evenly until it snaps back into place. Avoid forcing it unevenly, which could deform the gasket or the case.

For screw-back covers, realign the cover and tighten the screws evenly in a cross pattern to ensure even pressure distribution. Do not overtighten screws, as this can strip threads or crack the case.

Finally, test all watch functions once again to confirm proper operation. If the watch is rated for water resistance, consider having it professionally pressure tested to verify the seal integrity after battery replacement.
