If you own a Timex watch, you know how reliable and stylish these timepieces can be. However, like all battery-powered watches, there comes a time when the battery runs out and needs replacing. Knowing how to change the battery on your Timex watch not only saves you a trip to the jeweler but also gives you the satisfaction of maintaining your watch on your own.

Changing a Timex watch battery might seem daunting at first, especially if you’ve never opened a watch before. Yet, with a bit of patience and the right approach, it’s a straightforward task that many watch owners can handle themselves. Understanding the basics of your watch’s design and the tools required can make the process smoother and help you avoid any accidental damage.

In the following sections, we’ll guide you through the essential steps and tips for successfully replacing your Timex watch battery. Whether your watch has a simple snap-back case or a more intricate design, you’ll gain the confidence needed to bring your timepiece back to life quickly and efficiently.

Removing the Back Cover of Your Timex Watch

Before accessing the battery, you must carefully remove the back cover of your Timex watch. The method to open the case depends on the model, as Timex watches typically have either a snap-back, screw-back, or four-screw case design.

For snap-back cases, which are common in many Timex models, use a thin, flat tool such as a case knife or a small flathead screwdriver. Carefully insert the tool into the small notch on the edge of the back cover and gently pry it open. Applying steady, even pressure is key to avoid bending or scratching the case.

Screw-back cases require a specialized watch case wrench. Align the prongs of the wrench with the notches on the case back and turn counterclockwise to unscrew. This process demands precision to prevent damage to the watch.

For four-screw designs, simply use a small screwdriver to remove the screws evenly. Place the screws in a safe location to avoid loss during the battery replacement process.

Identifying and Removing the Old Battery

Once the back cover is removed, the battery will be visible, often secured by a metal clip or a small retaining bar. Note the battery type and orientation before removal to ensure the correct replacement and proper installation.

To remove the battery:

  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting the battery or damaging internal components.
  • Gently release the retaining clip or bar if present.
  • Carefully lift the battery out of its compartment, noting the positive (+) and negative (-) sides.

Keep in mind that some Timex watches may have additional components such as a gasket or spacer ring around the battery. Handle these parts carefully to maintain water resistance after reassembly.

Choosing the Correct Replacement Battery

Selecting the proper replacement battery is crucial for the watch’s functionality and longevity. Timex watches commonly use silver oxide button cell batteries, but the exact type varies by model.

Refer to the battery code printed on the old battery or consult the watch’s manual. If uncertain, professional watch repair shops or authorized dealers can help identify the correct battery.

Common Timex Battery Codes Battery Type Voltage Approximate Diameter (mm)
SR626SW Silver Oxide 1.55 V 6.8
CR2016 Lithium 3 V 20.0
SR621SW Silver Oxide 1.55 V 6.8
CR2032 Lithium 3 V 20.0

When purchasing, always opt for high-quality batteries from reputable brands to ensure reliable performance.

Installing the New Battery and Reassembling the Watch

After acquiring the correct battery, proceed with installation by placing it in the compartment with the correct polarity. The positive side usually faces up, but verify this against the markings inside the watch.

Secure the battery with the clip or retaining bar, ensuring it is firmly in place without applying excessive force. Check that the battery is seated evenly and that no components have shifted during installation.

Before closing the back cover, inspect the gasket or O-ring for any signs of damage. Replace it if necessary to maintain water resistance.

When reassembling:

  • Snap-back cases: align the cover and press firmly until it clicks into place. Use a case press if available for an even seal.
  • Screw-back cases: screw the cover back on using the case wrench, tightening evenly without over-torquing.
  • Four-screw cases: replace and tighten all screws evenly.

Test the watch functions to confirm the battery replacement was successful and the watch is operating correctly.

Preparing to Change the Battery on a Timex Watch

Before beginning the battery replacement process on a Timex watch, gather the necessary tools and create a clean, well-lit workspace to prevent loss of small components. A typical toolkit includes:

  • Small precision screwdriver set (flathead and Phillips)
  • Case back opener or a small knife for snap-back cases
  • Tweezers (preferably non-magnetic and plastic-tipped)
  • New battery compatible with the specific Timex watch model
  • Soft cloth or watch holder to prevent scratches

Additionally, identify the exact battery model by checking the current battery or consulting the watch manual. Common Timex watch batteries include types such as SR626SW or CR2016, but verify the specific model before purchase.

Removing the Watch Case Back Safely

Timex watches typically feature one of two types of case backs: snap-off or screw-off. Properly removing the case back is crucial to avoid damage.

Case Back Type Identification Removal Method
Snap-off Flat edge or small indentation on the perimeter Use a case knife or thin flathead screwdriver to gently pry open
Screw-off Notches or grooves around the back cover Use a case wrench or adjustable case opener to unscrew

To remove a snap-off back:

  • Place the watch face down on a soft cloth.
  • Locate the indentation and insert the edge of the case knife carefully.
  • Gently pry the back open without applying excessive force.

For screw-off backs:

  • Fit the case wrench into the notches.
  • Turn counterclockwise slowly to unscrew the back.
  • Remove the cover and set aside carefully.

Extracting and Replacing the Battery

Once the case back is removed, proceed with the battery replacement:

  • Identify the battery holder or retaining clip securing the battery.
  • Using tweezers or a small screwdriver, carefully release the clip or lift the battery out.
  • Avoid touching other components inside the watch to prevent damage or contamination.
  • Compare the old battery with the new one to confirm size and type.
  • Place the new battery into the compartment, ensuring correct polarity (usually positive side facing up).
  • Secure the battery by reattaching the clip or holder firmly but gently.

Handle the battery with care to avoid skin oils or static discharge that may affect its performance. Dispose of the old battery responsibly according to local regulations.

Reassembling the Watch After Battery Replacement

After installing the new battery, reassemble the watch to ensure it functions correctly and remains water-resistant if applicable.

  • Inspect the gasket or rubber seal around the case back for damage; replace if necessary to maintain water resistance.
  • Align the case back properly with the watch case.
  • For snap-off backs: Press firmly and evenly until the back snaps into place.
  • For screw-off backs: Screw the back on clockwise using the case wrench until snug but not overly tight.
  • Reset the watch time and any additional functions (e.g., alarms, chronograph).

Test the watch for proper operation and ensure the case back is securely fitted to prevent dust or moisture ingress.

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.
