AvatarByArmando Lewellen Usage Guides

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 need a battery replacement to maintain its reliable performance. Knowing how to change the battery yourself can save you time, money, and the hassle of visiting a watch repair shop.

Replacing the battery in an Armitron watch might seem daunting at first, especially if you’re unfamiliar with watch maintenance. However, with the right tools and a bit of patience, it’s a straightforward process that many watch owners can handle on their own. Understanding the basics of your watch’s design and battery type is key to ensuring a successful replacement without damaging the delicate components.

In the following sections, we’ll explore the essential steps and tips for changing the battery in your Armitron watch safely and efficiently. Whether you’re a seasoned DIY enthusiast or a first-timer, this guide will equip you with the knowledge to keep your watch ticking perfectly for years to come.

Accessing the Watch Back Cover

To begin the battery replacement process, you must first access the watch’s back cover. Armitron watches typically feature either a snap-off or screw-down back case, and identifying the type is crucial for selecting the correct removal method.

For snap-off backs, you will notice a small indentation along the edge of the case back. This is designed to accommodate a case knife or a flat tool to pry the cover open. Exercise caution to avoid scratching the watch or injuring yourself.

Screw-down backs are characterized by multiple notches or grooves around the perimeter of the back cover. These require a specialized case wrench or a similarly fitting tool to unscrew the cover. Applying even pressure and turning counterclockwise will loosen the back.

Ensure you work on a clean, flat surface with good lighting. Using a soft cloth underneath the watch can prevent scratches during handling.

Removing the Old Battery Safely

Once the back cover is removed, you will see the battery secured within the watch’s battery compartment. The battery is often held in place by a clip or a small screw.

Before proceeding, ground yourself to avoid static discharge, which can damage the watch’s internal electronics. Use plastic or non-metallic tweezers to handle the battery rather than metal tools.

Carefully:

  • Identify the battery type and note its orientation (positive and negative sides).
  • If there is a clip, gently lift or slide it aside.
  • If a screw secures the battery, use a precision screwdriver to remove it.
  • Extract the battery slowly to avoid dislodging other components.

Dispose of the old battery properly, as watch batteries contain hazardous materials.

Choosing the Correct Replacement Battery

Selecting the right replacement battery is essential for optimal watch performance. Armitron watches commonly use silver oxide button cells, but exact types vary by model.

Refer to the battery code printed on the old battery, which usually consists of alphanumeric characters such as “SR626SW” or “CR2032.” This code indicates voltage, size, and chemistry.

If the code is illegible, consult the watch manual or Armitron’s official support resources. Using an incorrect battery can lead to leakage, poor performance, or damage.

Battery Code Common Armitron Models Voltage (V) Diameter (mm) Height (mm)
SR626SW Digital & Analog 1.55 6.8 2.6
SR920SW Chronograph Models 1.55 9.5 2.1
CR2032 Some Digital Models 3.0 20.0 3.2

Installing the New Battery

With the correct battery at hand, installation should be performed with precision to ensure proper function.

  • Confirm the battery is clean and free of debris.
  • Place the new battery into the compartment, matching the orientation noted earlier (positive side usually faces up).
  • Secure the battery with the clip or screw without applying excessive force.
  • Double-check that the battery is seated firmly and that no components are loose.

Avoid touching the battery surface with bare hands, as oils and moisture can affect conductivity and cause corrosion over time.

Reassembling the Watch and Testing

After the battery installation, the next step is to reattach the watch back cover securely.

For snap-off backs:

  • Align the cover correctly with the case.
  • Press down evenly around the edges until it clicks into place. Using a watch press tool can ensure uniform pressure.

For screw-down backs:

  • Place the cover back onto the case.
  • Use the case wrench to tighten the back by turning clockwise.
  • Do not overtighten, as this can strip the threads.

Once reassembled, test the watch by checking its functions:

  • Verify the digital display or analog hands are working correctly.
  • Set the time and any additional features such as alarms or chronographs.
  • Monitor the watch for a few minutes to confirm steady operation.

If the watch does not power on, recheck battery orientation and contact placement before considering professional servicing.

Tools Recommended for Battery Replacement

Having the right tools simplifies the replacement process and minimizes the risk of damage:

  • Case knife or case opener tool (for snap-off backs)
  • Case wrench (for screw-down backs)
  • Precision screwdrivers (typically Phillips and flathead)
  • Plastic tweezers
  • Soft cloth or watchmaker’s pad
  • Watch press tool (optional but recommended)

Using purpose-built tools rather than improvised items will protect both you and your watch during the battery change.
