Knowing how to replace the battery in your Timex Expedition watch can save you time and money, allowing you to maintain your watch’s performance without a trip to the jeweler.

Replacing the battery in a Timex Expedition watch might seem daunting at first, especially if you’re unfamiliar with watch maintenance. Yet, with the right approach and tools, it’s a straightforward process that many watch owners can handle themselves. Understanding the basics of your watch’s design and the steps involved will empower you to extend the life of your timepiece confidently.

In the following sections, we’ll explore the essential considerations and general overview of battery replacement for Timex Expedition watches. Whether you’re a seasoned DIY enthusiast or a first-timer, this guide will prepare you to tackle the task with ease and care, ensuring your watch remains as dependable as ever.

Removing the Watch Back Cover

To access the battery inside your Timex Expedition watch, you first need to carefully remove the back cover. Timex Expedition models generally feature either a snap-back or screw-back case, so identifying which type your watch has is essential.

For a snap-back case, use a thin, flat tool such as a case knife or a small flat-head screwdriver. Gently insert the tool into the small notch on the edge of the case back and carefully pry it open. Apply steady, controlled pressure to avoid scratching or damaging the case.

If the watch has a screw-back case, you will need a case wrench or a suitable watch case opener designed for screw-back cases. Align the wrench’s pins with the notches on the case back, then turn counterclockwise to unscrew the cover. Avoid using excessive force to prevent stripping the notches.

Before proceeding, ensure you are working in a clean, well-lit environment and place the watch on a soft cloth to prevent scratches.

Identifying and Removing the Battery

Once the back cover is removed, you will see the internal components of the watch. The battery is typically held in place by a small metal clip or retaining arm. Identifying the battery type and size is crucial for replacement.

  • Observe the battery for any markings indicating its model number (e.g., CR2016, CR2025).
  • Take a photo or note the battery’s position and orientation to assist in correct reinstallation.

To remove the battery:

  • Use plastic tweezers or a non-metallic tool to gently lift the retaining clip or arm.
  • Carefully remove the battery, avoiding contact with the watch’s circuitry.

If the battery is corroded or stuck, avoid forcing it out. Instead, seek professional assistance to prevent damage.

Choosing the Correct Replacement Battery

Selecting the appropriate replacement battery ensures optimal performance and longevity of your Timex Expedition watch. Refer to the battery model number found on the old battery or consult the watch manual for specifications.

Battery Model Voltage Typical Diameter Common Timex Models
CR2016 3V 20mm Expedition Scout, Classic
CR2025 3V 20mm Expedition Field Chronograph
CR1632 3V 16mm Expedition Gallatin

Always purchase batteries from reputable brands to ensure quality and avoid leakage. Avoid mixing different battery brands or types within the watch.

Installing the New Battery

Before installing the new battery, verify that it matches the original in size and voltage. Handle the battery with clean hands or plastic tweezers to prevent contamination.

  • Place the battery in the compartment with the positive (+) side facing the correct direction, as noted during removal.
  • Gently secure the battery under the retaining clip or arm without applying excessive pressure.
  • Check that the battery sits flat and is firmly in place to maintain proper contact.

If the watch has a gasket or rubber seal around the case back, inspect it for wear or damage. Replace the gasket if necessary to maintain water resistance.

Reattaching the Watch Back Cover

After installing the new battery, carefully reattach the watch back cover to protect the internal components.

For snap-back cases:

  • Align the cover with the case, ensuring any notches or markings are properly oriented.
  • Press down firmly and evenly around the edges until the cover snaps securely into place.
  • Avoid using excessive force in one spot to prevent bending or cracking the cover.

For screw-back cases:

  • Align the threads and carefully screw the back cover clockwise using the case wrench.
  • Tighten until snug, but do not overtighten as this can damage the threads or gasket.

Once the cover is secured, test the watch functions to confirm the battery replacement was successful.

Additional Tips and Precautions

  • Avoid touching the new battery with bare fingers as oils and dirt can reduce battery life.
  • Use appropriate watch repair tools to minimize risk of damage.
  • Dispose of the old battery responsibly according to local regulations.
  • If uncertain or uncomfortable performing any step, consult a professional watch technician.
  • Regularly check the watch’s water resistance after battery replacement, especially if you frequently expose it to water.

By following these detailed steps and precautions, you can confidently replace the battery in your Timex Expedition watch while maintaining its reliability and performance.

Accessing the Battery Compartment

To replace the battery in a Timex Expedition watch, the initial step involves gaining access to the battery compartment, typically located on the back of the watch case. This process requires careful handling to avoid damaging the watch or its internal components.

Follow these steps to open the watch case safely:

  • Prepare a clean workspace: Use a soft cloth or pad to prevent scratches on the watch surface.
  • Identify the case back type: Timex Expedition watches commonly feature one of the following:
    • Screw-down case back: Characterized by multiple small notches around the edge, requiring a case back wrench or specialized tool.
    • Snap-on case back: A flat back that can be pried open with a thin blade or case knife.
  • Gather appropriate tools: A watch case opener tool, a small screwdriver, or a case knife, depending on the case back type.
  • Remove the case back:
    • For screw-down backs, align the case opener tool with the notches and gently turn counterclockwise.
    • For snap-on backs, insert the case knife into the small gap and carefully pry the back off.

Ensure the watch is held firmly but gently during this process to avoid slipping and causing damage.

Identifying and Removing the Old Battery

Once the case back is removed, the battery compartment becomes visible. Proper identification of the battery type and safe removal are critical steps.

Proceed with the following guidelines:

  • Locate the battery: Typically a small, round silver cell held in place by a clip or small screw.
  • Note the battery code: The battery will have an alphanumeric code printed on its surface (e.g., CR2016, SR626SW). Record this code to purchase the correct replacement.
  • Remove the battery:
    • If secured by a clip, gently lift or slide the clip aside using a non-metallic tool to avoid short circuits.
    • If secured by a screw, use a precision screwdriver to remove the screw carefully.
    • Use tweezers or a small plastic tool to lift the battery out, avoiding contact with metal tools that could cause damage.

Installing the New Battery and Reassembling

After removing the old battery, installing the new one requires precision to ensure the watch functions properly and remains water-resistant.

Follow these steps for installation:

  • Insert the new battery: Place the replacement battery in the compartment with the correct polarity; the positive side (+) is usually facing up.
  • Secure the battery: Replace the clip or screw, ensuring it is firmly holding the battery without applying excessive force.
  • Check the watch functionality: Before sealing the case back, verify that the watch display or hands are working.
  • Clean the gasket: Inspect the rubber gasket that seals the case back for debris or damage. Wipe it clean or replace it if necessary to maintain water resistance.
  • Replace the case back:
    • For screw-down backs, align the back and use the case opener tool to screw it clockwise until snug. Avoid overtightening.
    • For snap-on backs, press firmly around the edges until it snaps securely into place.

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.
