Tools Required for Battery Replacement

Before beginning the battery replacement process on your Timex Expedition watch, it is essential to gather the necessary tools to ensure the procedure is efficient and safe. Having the correct tools minimizes the risk of damaging the watch components.

The most commonly required tools include:

  • Precision screwdriver set: Typically, a small Phillips or flathead screwdriver is needed to remove the back cover screws.
  • Case back opener: For models with snap-off backs, a specialized pry tool helps avoid scratches.
  • Plastic tweezers: To handle the battery safely without short-circuiting.
  • Replacement battery: Confirm the correct battery type by checking the existing battery or the watch manual.
  • Soft cloth or mat: To place the watch on and protect it from scratches during the process.
  • Magnifying glass: Optional, but helpful for small components.

Having these tools ready will streamline the battery change and protect your watch from accidental damage.

Identifying the Correct Battery Type

Timex Expedition watches use various battery types depending on the model and features. Using an incorrect battery can impair functionality or damage the watch.

To identify the correct battery:

  • Remove the back cover carefully.
  • Locate the battery and note any markings, usually a series of numbers and letters.
  • Refer to the Timex user manual or official website for model-specific battery information.
  • Consult the table below for common Timex Expedition battery types:
Timex Expedition Model Battery Type Battery Code Voltage
Expedition Field Chronograph Silver Oxide SR927SW 1.55V
Expedition Scout Silver Oxide CR2016 3V
Expedition Gallatin Silver Oxide SR626SW 1.55V
Expedition Rugged Silver Oxide CR2025 3V

If uncertain, bring the old battery to a watch repair shop or electronics store to verify compatibility with the replacement.

Removing the Back Cover

The method to remove the back cover varies depending on whether your Timex Expedition watch has a screw-down case back or a snap-off case back.

For screw-down case backs:

  • Use a precision screwdriver to carefully unscrew the small screws holding the back plate.
  • Keep the screws in a safe place as they are very small and easy to lose.
  • Lift the back cover gently to avoid damaging the gasket or internal components.

For snap-off case backs:

  • Locate the small notch or indentation along the case back edge.
  • Insert a case back opener or a thin, flat tool into the notch.
  • Apply gentle, steady pressure to pry the back cover off.
  • Work slowly to prevent bending or scratching the case back.

In either case, place the watch on a soft cloth to protect the surface and avoid any slippage during the process.

Removing and Replacing the Battery

Once the back cover is removed, the battery will be visible, often secured by a small clip or retaining arm.

To remove the battery safely:

  • Note the orientation of the battery (positive and negative sides).
  • If a clip holds the battery, gently lift or slide it away using plastic tweezers or a non-metallic tool.
  • Avoid using metal tools that can short the battery or damage the watch’s circuitry.
  • Carefully extract the battery with plastic tweezers.

For inserting the new battery:

  • Align the new battery in the same orientation as the old one.
  • Slide it into place, ensuring the retaining clip secures it without exerting excessive force.
  • Double-check that the battery sits flat and contacts the terminals properly.

Reassembling the Watch

After the battery replacement, reassemble the watch carefully to maintain its water resistance and mechanical integrity.

  • Inspect the gasket or rubber seal around the case back for any damage or debris; replace it if necessary to preserve water resistance.
  • Align the back cover correctly with the watch case.
  • For screw-down backs, tighten screws evenly and securely but avoid overtightening to prevent stripping.
  • For snap-off backs, press the cover firmly until it snaps into place, ensuring no gaps remain.

Finally, test the watch to confirm it is functioning correctly and that all features respond as expected.

Additional Tips for Safe Battery Replacement

  • Work in a clean, well-lit area to avoid losing small parts.
  • Avoid touching the battery terminals with bare hands to prevent corrosion.
  • Dispose of old batteries responsibly, following local regulations.
  • If the watch has complex features such as sensors or digital displays, consider professional servicing.
  • Keep the watch away from magnets during the process to prevent interference.

Following these detailed steps ensures a successful battery replacement in your Timex Expedition watch, maintaining its reliability and performance.

Preparing to Change the Battery in Your Timex Expedition Watch

Before beginning the battery replacement process, it is crucial to gather all necessary tools and ensure a clean, well-lit workspace to avoid losing small components. The following items are typically required:

  • Replacement battery (verify the correct battery model for your Timex Expedition, often a silver oxide button cell like CR2016 or similar)
  • Small flathead or Phillips screwdriver
  • Case back opener tool or a small, thin blade
  • Tweezers (preferably non-metallic to avoid short circuits)
  • Soft cloth or watch cushion to protect the watch face
  • Plastic or wooden toothpick (optional, for delicate component handling)

It is important to verify the exact battery type compatible with your specific Timex Expedition model, which can be found in the user manual or by referencing the existing battery code. Using an incorrect battery can damage the watch or result in improper functionality.

Removing the Case Back of the Timex Expedition Watch

Timex Expedition watches commonly feature either a snap-off or screw-back case. Identifying the type of case back is necessary to proceed correctly.

Case Back Type Description Removal Method
Snap-Off Flat back with a small indentation or notch on the edge Use a case knife or thin blade inserted into the notch to gently pry the back off
Screw-Back Back with multiple small indentations or grooves along the edge Use a case wrench or adjustable tool to unscrew the back counterclockwise

When removing the case back:

  • Place the watch face down on a soft cloth to prevent scratches.
  • Apply gentle, steady pressure when prying or unscrewing the case back.
  • Be cautious not to damage the rubber gasket that provides water resistance.

Extracting and Identifying the Old Battery

Once the case back is removed, you will see the internal components of the watch, including the battery holder.

  • Locate the battery, which is usually secured under a small metal clip or retaining arm.
  • If a clip holds the battery, carefully lift it using a small screwdriver or plastic tool.
  • Use tweezers to gently remove the battery to avoid touching other components or causing static discharge.

Take note of the battery’s orientation (positive and negative sides) before removal to ensure correct placement of the new battery.

Installing the New Battery and Reassembling the Watch

After removing the old battery, proceed as follows:

  • Insert the new battery in the exact orientation as the original one.
  • Secure the battery under the retaining clip if applicable, ensuring it is firmly seated.
  • Check that the watch starts running immediately, indicating proper installation.

Before replacing the case back:

  • Inspect and, if necessary, lightly lubricate the rubber gasket with silicone grease to maintain water resistance.
  • Ensure the gasket is properly seated in its groove.

To close the case back:

  • For snap-off backs, align the case back correctly and press down firmly until it snaps into place. Using a case press tool is recommended to apply even pressure.
  • For screw-back cases, carefully screw the back on clockwise using the case wrench, avoiding cross-threading.

Final checks:

  • Confirm the watch is functioning correctly and the hands move as expected.
  • Set the time and date according to the manufacturer’s instructions.
  • Test buttons and other features to ensure full operation.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
