AvatarByArmando Lewellen Watch Brands

If you own a Timex Expedition watch, you know it’s a reliable companion built to withstand the rigors of outdoor adventures. However, even the toughest timepieces eventually need a battery replacement to keep ticking accurately. Knowing how to change the battery in a Timex Expedition watch not only saves you time and money but also ensures your watch remains ready for your next journey.

Replacing the battery in a Timex Expedition is a straightforward process, but it requires a bit of care and the right tools to avoid damaging the watch’s delicate components. Understanding the basic structure of your watch and the type of battery it uses is essential before you begin. This knowledge helps you approach the task with confidence and precision.

Whether you’re a seasoned DIY enthusiast or a first-timer looking to extend the life of your watch, learning the proper way to change the battery can be empowering. In the sections ahead, we’ll guide you through the essentials, preparing you to maintain your Timex Expedition’s performance without the need for professional assistance.

Opening the Watch Case

Before you can replace the battery in your Timex Expedition watch, you need to carefully open the watch case. Most Timex Expedition models feature a snap-back or screw-back case, and the method of opening varies accordingly.

For snap-back cases, use a case knife or a thin, flat tool to gently pry open the back. Locate the small indentation or lip on the edge of the case back and carefully insert the tool. Apply gentle pressure to lift the case back without damaging the watch.

For screw-back cases, you will need a specialized case wrench or a case opener tool. Align the tool’s pins with the notches on the case back and turn counterclockwise to unscrew the back. Be sure to work on a clean, flat surface to avoid losing any small components.

When opening the case, take the following precautions:

  • Work in a well-lit area.
  • Use a soft cloth or pad to protect the watch face and avoid scratches.
  • Avoid using excessive force to prevent bending or breaking the case back.

Removing and Identifying the Battery

Once the case is open, you will see the battery secured under a retaining clip or small metal arm. Use non-metal tweezers or a plastic tool to carefully release the clip and lift the battery out of its compartment.

Take note of the battery type and size, which is usually printed on the battery itself. Timex Expedition watches commonly use silver oxide button cell batteries, but the exact model can vary.

To help you identify the correct replacement battery, here is a table of common Timex Expedition battery types and their characteristics:

Battery Model Voltage Diameter (mm) Thickness (mm) Common Usage
SR626SW (377) 1.55 V 6.8 2.6 Standard Timex Expedition models
SR920SW (370) 1.55 V 9.5 2.1 Models with larger battery compartments
CR2016 3 V 20 1.6 Digital Timex Expedition watches

If the battery is corroded or leaking, carefully clean the compartment with a cotton swab lightly dampened with isopropyl alcohol. Avoid using excessive moisture, as this can damage the internal components.

Installing the New Battery

When you have the correct replacement battery, carefully insert it into the battery compartment with the positive (+) side facing up, unless otherwise indicated. Ensure the battery sits flat and is properly aligned within the compartment.

Re-secure the retaining clip or metal arm to hold the battery in place, taking care not to exert too much pressure that could damage the battery or contacts.

After installing the battery, check that the watch hands or digital display are functioning. If the watch does not immediately respond, verify the battery orientation and ensure the contacts are clean and making good contact with the battery.

Resealing the Watch Case

To maintain water resistance and protect the watch internals, resealing the case correctly is crucial. First, inspect the rubber gasket or O-ring around the case back for any signs of damage or wear. Replace it if necessary to maintain a proper seal.

For snap-back cases:

  • Align the case back with the watch case.
  • Press firmly around the edges using your thumbs or a case press tool until it snaps into place.

For screw-back cases:

  • Place the gasket in position.
  • Screw the back on clockwise using the case wrench, ensuring it is snug but not over-tightened to avoid stripping the threads.

Additional Tips for Battery Replacement

  • Always use a high-quality replacement battery from a reputable brand to ensure longevity and reliability.
  • Avoid touching the new battery with bare hands; oils and dirt can reduce battery life. Use tweezers or gloves.
  • If your watch has a water resistance rating, consider having a professional test the seal after battery replacement to ensure continued protection.
  • Keep a small container or magnetic tray nearby to store screws and small parts to prevent loss.

Following these detailed steps will help you replace the battery in your Timex Expedition watch safely and effectively.

Preparing to Replace the Battery in Your Timex Expedition Watch

Before beginning the battery replacement process, ensure you have the correct tools and a suitable workspace. This preparation will help avoid damage to the watch and ensure a smooth battery change.

Gather the following items:

  • Replacement battery compatible with your Timex Expedition model (commonly CR2016 or CR2025, verify your specific model)
  • Small precision screwdriver set (typically Phillips or flathead depending on the case back screws)
  • Case back opener tool or a small knife for snap-back cases
  • Plastic tweezers to handle the battery (prevents static discharge and corrosion)
  • Soft cloth or pad to work on, preventing scratches to the watch
  • Optional: magnifying glass or loupe for better visibility

Ensure you work in a clean, well-lit area free from dust and moisture. Ground yourself if possible to avoid static damage, especially when handling electronic components.

Removing the Case Back of the Timex Expedition Watch

The method of accessing the battery compartment varies depending on the watch model. Timex Expedition watches commonly have either a snap-off or screw-down case back.

Case Back Type Identification Removal Method
Snap-Off Flat edge with a small indentation or lip Use a case knife or thin blade to gently pry open at the indentation
Screw-Down Multiple small screws holding the back plate Use an appropriate precision screwdriver to remove all screws

Step-by-step removal for Snap-Off Case Back:

  • Place the watch face down on a soft cloth.
  • Locate the small indentation on the case back edge.
  • Insert the case knife carefully into the indentation.
  • Apply gentle pressure to pry the back off, avoiding bending or damaging the case.

Step-by-step removal for Screw-Down Case Back:

  • Place the watch face down on a soft surface.
  • Use the correct size screwdriver to remove each screw systematically.
  • Keep screws in a safe place to prevent loss.
  • Lift the back cover carefully once all screws are removed.

Extracting and Replacing the Battery Safely

Once the case back is removed, you will see the battery secured in place by a clip or a small retaining arm. Proceed carefully to avoid damaging internal components.

  • Identify the battery type and orientation (note the positive “+” side direction).
  • Use plastic tweezers or a non-metallic tool to gently lift or slide the battery out of its compartment.
  • Avoid touching the new battery with bare hands to prevent corrosion from skin oils.
  • Insert the new battery in the same orientation as the old one, ensuring it sits flush and securely under any retaining clips.

Verify the battery compartment is clean and free from debris before replacing the battery. If corrosion or residue is present, carefully clean with a cotton swab and a small amount of isopropyl alcohol.

Reassembling the Watch and Testing Functionality

After installing the new battery, reattach the case back carefully to maintain water resistance and protect internal components.

  • For Snap-Off Case Backs: Align the back cover correctly and press firmly around the edges until it clicks into place. Use a case press if available to avoid uneven pressure.
  • For Screw-Down Case Backs: Position the back cover and replace all screws, tightening them evenly without over-tightening to avoid stripping threads.

Once reassembled, check the watch functions thoroughly:

  • Confirm the digital or analog display is operational.
  • Test all buttons for responsiveness (e.g., mode, light, stopwatch).
  • Set the correct time and date if necessary.
  • Observe the watch for several minutes to ensure consistent operation.

If the watch does not power on, recheck battery orientation and contact points. If problems persist, professional servicing may be required.
