AvatarByArmando Lewellen Watch Brands

When your trusty Citizen watch starts to lose its tick or the display begins to fade, it’s often a clear sign that the battery needs replacing. Knowing how to change the battery in a Citizen watch can save you time, money, and the hassle of visiting a professional every time your timepiece runs low. Whether you own a classic analog model or a more advanced digital version, understanding the basics of battery replacement empowers you to keep your watch running smoothly and accurately.

Changing the battery in a Citizen watch might seem daunting at first, especially given the precision and care these timepieces require. However, with the right approach and tools, it’s a manageable task that can extend the life of your watch significantly. This process involves more than just popping out the old battery and inserting a new one; it requires attention to detail to ensure your watch remains water-resistant and fully functional.

In the following sections, we’ll explore the essential considerations and general steps involved in replacing a Citizen watch battery. Whether you’re a seasoned DIY enthusiast or a beginner looking to learn, this guide will prepare you to tackle the job confidently and safely.

Removing the Back Cover

To access the battery compartment of a Citizen watch, the first step is to remove the back cover. The method to remove the back cover varies depending on the model of the watch. Generally, Citizen watches feature one of the following types of case backs:

  • Snap-off case backs: These are pressed into place and require prying tools.
  • Screw-down case backs: These have notches around the perimeter for a case wrench.
  • Screw-in case backs with screws: Small screws hold the back cover in place.

Before proceeding, ensure you have the appropriate tools such as a case knife, case wrench, or precision screwdriver. Work on a clean, well-lit surface to avoid losing small parts.

For snap-off case backs, gently insert a case knife into the small gap between the back cover and the watch case. Carefully pry the cover upward by applying steady pressure until it pops off. Avoid forcing the cover, as excessive force may damage the watch case or gasket.

For screw-down case backs, align a case wrench with the notches and turn counterclockwise to unscrew the cover. If your watch has screws, use a precision screwdriver to remove them before lifting the back cover.

Identifying and Removing the Old Battery

Once the back cover is removed, locate the battery compartment. The battery is usually held in place by a small metal clip or a retaining arm. Take note of the battery type by reading the numbers printed on its surface; this is essential for purchasing the correct replacement.

To remove the battery:

  • Use non-metallic tweezers or a plastic tool to gently lift the retaining clip if present.
  • Carefully extract the battery without touching other components.
  • Avoid using metal tools to prevent short circuits or damage.

Handle the battery and internal components with care to maintain the watch’s functionality.

Inserting the New Battery

Before inserting the new battery, verify that it matches the original in size and voltage. Using an incompatible battery can damage the watch or cause malfunction.

Place the new battery in the compartment with the correct polarity orientation. Typically, the positive side (+) faces upward, but confirm this based on the watch’s markings or the original battery position.

Secure the battery by replacing the retaining clip or arm carefully. Ensure the battery sits flush within the compartment to avoid interference with internal mechanisms.

Testing the Watch and Replacing the Back Cover

After installing the new battery, test the watch to confirm it is functioning properly. Look for the following signs:

  • The second hand moving smoothly.
  • Digital displays turning on (if applicable).
  • Alarm or other functions responding as expected.

If the watch does not start immediately, gently press the crown or reset button according to the user manual.

When satisfied with the watch’s operation, replace the back cover. Align it carefully and press or screw it back into place using the reverse method of removal. Ensure the gasket or rubber seal is properly seated to maintain water resistance.

Watch Back Type Tool Required Removal Method Reinstallation Tips
Snap-off Case knife Pry gently at the gap Press firmly until it snaps back
Screw-down Case wrench Turn counterclockwise to unscrew Align threads and screw clockwise securely
Screw-in with screws Precision screwdriver Remove screws, lift cover Replace screws evenly and snugly

Preparing to Replace the Battery in Your Citizen Watch

Before beginning the battery replacement process, ensure you have the necessary tools and environment to work safely and effectively. Replacing a watch battery requires precision and care to avoid damaging delicate internal components.

  • Tools Needed:
    • Watch case opener (case knife or case wrench, depending on the model)
    • Plastic tweezers (to avoid shorting the battery)
    • Small screwdriver set (typically Phillips or flathead)
    • New battery compatible with your Citizen watch model
    • Soft cloth or mat to protect the watch and workspace
    • Magnifying glass or loupe (optional, for better visibility)
  • Safety Precautions:
    • Work in a clean, well-lit area free of dust and moisture.
    • Avoid touching the battery with bare hands to prevent corrosion from skin oils.
    • Be gentle with the watch components to prevent damage to seals and movement.
  • Battery Identification:
    Determine the exact battery type by checking the existing battery or consulting the watch manual. Citizen watches commonly use silver oxide batteries such as SR626SW or equivalent.

Accessing the Back Case of Your Citizen Watch

Citizen watches typically feature either a snap-back case or a screw-down back. Identifying the type of case back is essential for selecting the appropriate opening method.

Case Back Type Identification Opening Method
Snap-back Flat back with a small indentation or lip for prying Use a case knife to carefully pry open
Screw-down Back with multiple notches or grooves around the edge Use a case wrench or adjustable opener to unscrew
  • Place the watch face down on a soft cloth to protect the crystal and bezel.
  • For snap-back cases, insert the case knife into the indentation and gently twist to pop the back off.
  • For screw-down backs, align the case wrench with the notches and turn counterclockwise to unscrew.
  • Handle the case back carefully and set it aside on a clean surface.

Removing the Old Battery and Installing the New One

With the case back removed, you will have access to the watch movement and battery compartment.

  • Identify the battery, which is usually held in place by a small clip or retaining bar.
  • Using the appropriate small screwdriver, carefully loosen the screw(s) securing the clip or gently lift the clip if it is a spring-type retainer.
  • Use plastic tweezers to remove the old battery, avoiding metal tools that could cause short circuits.
  • Check the battery compartment and contacts for any dirt or corrosion; clean gently with a dry cloth if necessary.
  • Insert the new battery with the correct polarity orientation (usually positive side facing up). Refer to markings inside the battery compartment or the old battery for guidance.
  • Secure the battery by replacing the clip or screw.
  • Before reassembling, verify the watch is functioning correctly by checking if the second hand or digital display is active.

Reassembling the Watch and Final Checks

Proper reassembly ensures the watch maintains its water resistance and structural integrity.

  • Inspect the case back gasket or rubber seal for any damage or dirt. Replace if necessary to maintain water resistance.
  • For snap-back cases, align the case back and press firmly around the edges until it snaps into place. Using a case press can help apply even pressure.
  • For screw-down backs, align the threads and carefully screw the case back clockwise using the case wrench. Avoid overtightening to prevent damage.
  • Clean the exterior of the watch with a soft cloth to remove fingerprints or smudges.
  • Set the time and date as required.
  • Confirm all functions are working properly before wearing the watch again.
