Replacing the battery on your Timex watch can breathe new life into a timepiece you love, saving you the cost and hassle of buying a new one. Whether your watch has stopped ticking or is running slow, a fresh battery often restores its reliable performance. Understanding how to replace the battery yourself not only empowers you with a handy skill but also allows you to maintain your watch’s longevity with ease.

Timex watches come in various styles and models, each with its own unique design and battery requirements. While the process may seem daunting at first, many Timex watches are designed with user-friendly access to the battery compartment. Gaining a general overview of the tools involved and the steps to safely open the watch case can make the task approachable even for beginners.

In the following sections, you’ll discover essential tips and guidelines to help you confidently replace your Timex watch battery. From identifying the right battery type to ensuring your watch remains water-resistant after the change, the insights provided will prepare you to handle the replacement smoothly and effectively.

Accessing the Watch Back

To replace the battery on a Timex watch, the first step is to carefully access the watch back. Timex watches typically have either a snap-off back or a screw-down back, and identifying which type you have is crucial to avoid damage.

For a snap-off back:

  • Locate the small indentation or lip on the edge of the watch back.
  • Use a thin, flat tool like a watch case opener or a small flathead screwdriver.
  • Gently insert the tool into the indentation and apply slight upward pressure to pry the back off.
  • Work slowly to prevent scratching or bending the case back.

For a screw-down back:

  • Identify the notches or grooves around the perimeter of the case back.
  • Use a case wrench or a pair of adjustable watch case opening pliers.
  • Align the tool with the notches and turn counterclockwise to unscrew.
  • Take care to apply even pressure and avoid slipping.

Once the back is removed, place it safely aside, ensuring you do not lose any small parts such as the gasket or screws, which are essential for maintaining water resistance.

Removing and Identifying the Battery

After exposing the inner workings of the watch, the next step involves locating and removing the battery.

  • The battery is typically held in place by a small metal clip or retainer.
  • Use non-magnetic tweezers to avoid damaging the watch’s delicate components.
  • Carefully lift or unscrew the clip securing the battery.
  • Remove the battery gently, noting its orientation (positive and negative sides).

Identifying the correct battery type is critical for proper function. Timex watches commonly use standard silver oxide button cell batteries, but the exact model can vary.

Battery Model Typical Timex Watch Models Voltage Diameter (mm) Height (mm)
SR626SW (377) Classic analog Timex 1.55 V 6.8 2.6
CR2016 Digital Timex models 3 V 20 1.6
SR920SW (370/371) Chronograph Timex watches 1.55 V 9.5 2.1

Verify the battery number printed on the old battery before purchasing a replacement to ensure compatibility.

Installing the New Battery

When installing the replacement battery, precision and cleanliness are essential to avoid damaging the watch’s movement.

  • Use tweezers to position the new battery exactly as the old one was oriented.
  • Ensure the positive (+) side faces the correct direction, usually upward.
  • Secure the battery with the clip or retainer, confirming it is firmly in place.
  • Avoid touching the battery surface with your fingers to prevent corrosion or reduced battery life.

After installing the battery, check that the watch hands or digital display activate, indicating successful power restoration.

Reassembling the Watch

Reassembly requires careful attention to maintain the watch’s water resistance and structural integrity.

  • Inspect the gasket (rubber seal) around the case back; if damaged or dried out, replace it to preserve water resistance.
  • For snap-off backs, align the back cover carefully with the case and press firmly until it snaps into place. Using a watch press tool can help apply even pressure.
  • For screw-down backs, place the cover and turn clockwise using the case wrench or pliers until snug. Do not overtighten, as this may strip the threads.
  • Confirm the back is securely attached and the watch case is flush without gaps.

Testing and Final Checks

Once reassembled, perform several checks to ensure your Timex watch functions correctly:

  • Set the time and date to verify the crown and buttons work smoothly.
  • Observe the watch for a few minutes to confirm the hands move or the digital display remains stable.
  • For water-resistant models, avoid submerging immediately after battery replacement. Allow the gasket to settle, or have the watch pressure-tested professionally.

By following these detailed steps, you can confidently replace the battery on your Timex watch while maintaining its performance and longevity.

Identifying the Battery Type for Your Timex Watch

Before beginning the replacement process, it is crucial to determine the correct battery type for your Timex watch. Using the appropriate battery ensures proper functionality and prevents damage.

  • Check the Watch Back: Most Timex watches have the battery type engraved or printed on the back case. Look for a series of numbers and letters such as “CR2016” or “SR626SW.”
  • Consult the User Manual: The original manual or packaging often specifies the recommended battery model.
  • Online Resources: Visit the Timex official website or authorized retailers for model-specific battery information.
  • Use a Battery Tester: If unsure, a jeweler or watch technician can test the existing battery to identify its type.
Common Timex Battery Types Typical Battery Code Voltage Approximate Diameter (mm)
Silver Oxide SR626SW (377) 1.55 V 6.8
Lithium Coin Cell CR2016 3 V 20
Alkaline Button Cell LR44 1.5 V 11.6

    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.
