It’s important to recognize that Citizen offers a variety of watch models, each with unique designs and battery requirements, which means a one-size-fits-all method doesn’t apply. Knowing the general process and what to expect can help you approach the task confidently and avoid common pitfalls.

In the following sections, you’ll find an overview of the essential steps involved in replacing your Citizen watch battery, along with helpful tips to ensure a safe and successful replacement. Whether you’re a seasoned DIY enthusiast or a first-time watch maintainer, this guide will prepare you to handle your watch’s battery change with ease and care.

Opening the Watch Case

Before replacing the battery on your Citizen watch, it is essential to carefully open the watch case to access the battery compartment. Citizen watches typically feature either a snap-back case or a screw-back case, and the method to open each varies.

For a snap-back case, use a case knife or a thin, flat tool designed for watch repair. Insert the tool gently into the small indentation or lip on the edge of the case back and apply slight pressure to pry it open. Be cautious to avoid scratching or damaging the watch case.

For a screw-back case, a specialized case wrench with adjustable pins is required. Align the pins with the notches on the case back and turn counterclockwise to unscrew the back. If the case back is stuck, apply gentle pressure or use a rubber ball to improve grip before attempting again.

When handling the opened case, place it on a clean, soft surface to prevent damage or loss of small parts. Additionally, it is advisable to work in a dust-free environment to avoid contaminating the watch’s internal components.

Removing and Identifying the Old Battery

Once the case is open, locate the battery, typically held in place by a small metal clip or a plastic cover secured with screws. Use a small screwdriver or tweezers to carefully remove these fasteners.

Gently lift the battery out using non-metallic tweezers to avoid short-circuiting or damaging the battery contacts. Avoid using excessive force, which can damage the battery compartment or the watch movement.

After removal, examine the battery for the model number, which is usually printed on the flat side. This information is crucial to ensure you purchase the correct replacement battery. Citizen watches commonly use silver oxide batteries, but some models may require lithium or other specialized types.

Below is a reference table of common Citizen watch battery types and their corresponding model numbers:

Battery Model Type Voltage Approximate Diameter (mm) Approximate Thickness (mm)
SR920SW Silver Oxide 1.55V 9.5 2.1
SR626SW Silver Oxide 1.55V 6.8 2.6
CR2016 Lithium 3V 20.0 1.6
SR927W Silver Oxide 1.55V 9.5 2.7

Installing the New Battery

Before installing the new battery, clean the battery compartment gently with a soft brush or blower to remove any dust or debris. Avoid touching the new battery with bare hands; use plastic tweezers or gloves to prevent corrosion from skin oils.

Place the new battery in the compartment, ensuring the correct polarity. The positive side, often marked with a “+”, should face upward or align as per the watch’s battery holder design. Confirm that the battery sits flat and secure under any retaining clips or covers.

After installing, check that the watch starts ticking or the digital display powers on, indicating the battery is functioning properly. If the watch does not start, recheck the battery placement and contacts for proper alignment.

Closing the Watch Case

Once the new battery is installed and functioning, it is time to close the watch case carefully. For snap-back cases, align the case back with the watch body and press down firmly and evenly until it snaps into place. Using a watch press tool can help apply even pressure and prevent damage.

For screw-back cases, place the case back on and use the case wrench to turn clockwise until it is securely tightened. Avoid over-tightening, which can strip threads or damage the gasket.

Ensure the case back gasket is intact and properly seated before closing. This gasket is critical for maintaining water resistance. If the gasket is damaged or dried out, replace it to preserve the watch’s integrity.

Testing and Final Checks

After closing the case, perform the following checks to ensure the watch is fully operational and protected:

  • Verify the watch is running accurately and the hands or display function correctly.
  • Test the buttons and crown to confirm proper operation.
  • Inspect the case back seal to ensure there are no visible gaps.
  • If the watch is water-resistant, consider testing it for water resistance at a professional service center to maintain warranty and reliability.

Proper care during the battery replacement process will extend the life of your Citizen watch and maintain its performance.

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.
