AvatarByArron Moss Watch Maintenance

If you own an Armitron watch, you know how essential it is to keep it running smoothly and accurately. Over time, like all battery-powered timepieces, your Armitron watch will eventually require a battery replacement to maintain its performance. Understanding how to change the battery yourself can save you time and money, while also giving you the satisfaction of maintaining your watch independently.

Changing the battery in an Armitron watch is a straightforward process, but it does require some care and the right tools to avoid damaging the delicate components. Whether your watch has a simple snap-back case or a more intricate design, knowing what to expect before opening it up is crucial. This overview will guide you through the general considerations and preparations needed before diving into the actual battery replacement.

By learning the basics of battery replacement for your Armitron watch, you’ll be better equipped to handle this common maintenance task with confidence. The following sections will provide clear guidance and helpful tips to ensure your watch continues to keep perfect time long after the new battery is installed.

Opening the Watch Case

To begin the battery replacement process, carefully open the back case of your Armitron watch. Most Armitron watches feature either a snap-back or screw-back case, and identifying the type is crucial for safe removal.

For snap-back cases, use a thin, flat tool such as a case knife or a precision flathead screwdriver. Insert the tool into the small notch on the case back and gently pry it open. Avoid using excessive force to prevent damaging the watch or injuring yourself.

Screw-back cases require a specialized watch case wrench or a case opener tool. Align the tool’s prongs with the notches on the case back and turn counterclockwise to unscrew. This method ensures even pressure and reduces the risk of scratching.

When handling the case back, place the watch on a soft, clean surface to avoid scratches. Additionally, wearing gloves or using a lint-free cloth can help keep the interior clean and free from oils.

Removing and Identifying the Battery

Once the back case is removed, locate the battery compartment. Armitron watches generally use button-cell batteries secured under a small metal clip or held in place by a retaining screw.

To remove the battery:

  • Use plastic tweezers or a non-metallic tool to lift the battery gently, avoiding short circuits.
  • If a retaining clip or screw is present, use a precision screwdriver to loosen it carefully.
  • Note the orientation of the battery before removal, as correct polarity is essential during replacement.

Identifying the battery type is straightforward by reading the alphanumeric code printed on the battery’s surface. Common Armitron watch batteries include types like SR626SW, SR621SW, or CR2025. Verify the code to ensure you purchase an exact replacement.

Battery Code Common Name Voltage Diameter (mm) Height (mm)
SR626SW 377 1.55V 6.8 2.6
SR621SW 364 1.55V 6.8 2.1
CR2025 CR2025 3V 20.0 2.5

Installing the New Battery

After procuring the correct replacement battery, install it with care to avoid damage. Use plastic tweezers or hold the battery with your fingers wrapped in a lint-free cloth to prevent moisture and oils from affecting contact points.

Place the battery in the compartment with the same polarity orientation as the original. Positive (+) side is usually facing up. Reattach any retaining clips or screws, ensuring they are secure but not overtightened.

Before closing the watch, check the watch’s functionality by observing if the display or hands begin moving. If the watch does not start, double-check battery placement and contacts for dirt or corrosion.

Sealing the Watch Case

Properly sealing the watch case is critical to maintain water resistance and protect the internal components. For snap-back cases, align the back cover with the watch body and press down firmly until it snaps into place. Using a watch press tool can help apply even pressure without damaging the watch.

For screw-back cases, place the case back carefully and use the case wrench to tighten it clockwise. Do not overtighten, as this can strip the threads or damage the gasket.

Inspect the gasket or rubber seal around the case back before closing. If it appears worn or damaged, replace it to preserve water resistance. Lubricating the gasket lightly with silicone grease can improve the seal and prolong gasket life.

Testing and Final Checks

After reassembling the watch, conduct a thorough check to ensure proper operation and sealing:

  • Confirm the watch is running and the display or hands are moving correctly.
  • Check that all buttons and crown functions operate smoothly.
  • Examine the case back for a tight, even seal with no gaps.
  • If your watch is water-resistant, avoid submerging it until you have confirmed the seal integrity or had it pressure-tested professionally.

By following these steps with precision and care, you can successfully replace the battery in your Armitron watch, restoring its functionality without compromising its durability or aesthetic.

Accessing the Back Cover of Your Armitron Watch

Before replacing the battery, you must first gain access to the watch’s internal compartment by removing the back cover. Armitron watches typically feature either a snap-back or screw-back case design. Identifying the type of back cover is essential for selecting the correct removal method.

  • Snap-back case: This style has a smooth edge with a small indentation or notch where a case knife can be inserted.
  • Screw-back case: This type features multiple notches or grooves around the perimeter for a case wrench.
Back Cover Type Removal Tool Removal Method
Snap-back Case knife or thin blade Insert blade into notch and gently pry open
Screw-back Case wrench or adjustable watch opener Align wrench teeth with notches and turn counterclockwise

When handling the case back, ensure you work on a clean, flat surface and use appropriate tools to avoid scratching or damaging the watch housing.

Removing the Old Battery Safely

Once the back cover is removed, the battery will be visible, often held in place by a small clip or retaining arm. Follow these professional steps to remove the battery without damaging internal components:

  • Identify the battery model number printed on the battery itself (commonly types such as SR626SW or CR2025).
  • Use plastic tweezers or a non-metallic tool to gently lift the retaining clip or arm securing the battery.
  • Carefully extract the battery, avoiding contact with other internal parts.
  • Inspect the battery compartment for any signs of corrosion or residue that should be cleaned before inserting the new battery.

Avoid using metal tools directly on the battery terminals to prevent short circuits or damage.

Installing the Replacement Battery Correctly

Proper placement of the new battery is critical to ensuring optimal watch performance. Use the following guidelines:

  • Match the new battery type exactly with the one removed, confirming size and voltage compatibility.
  • Insert the battery with the positive (+) side facing upward, as indicated by the battery compartment markings.
  • Secure the battery by gently repositioning any retaining clips or arms.
  • Before closing the case back, test the watch to confirm it is functioning correctly.

If the watch does not start, double-check the battery orientation and contact points for cleanliness.

Reassembling the Watch After Battery Replacement

After confirming the new battery functions properly, reattach the back cover with care to maintain water resistance and structural integrity.

  • For snap-back cases: Align the cover properly with the watch case and press firmly with your thumbs or a watch press tool until it snaps into place.
  • For screw-back cases: Position the cover so the notches align, then use the case wrench to screw it clockwise securely without over-tightening.
  • Inspect the gasket or rubber seal around the case back for any damage; replace it if necessary to preserve water resistance.

Proper reassembly ensures the watch remains protected from dust and moisture.

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.
