However, with the right approach and a bit of care, it’s a manageable task that many watch owners can handle on their own. Understanding the basics of your watch’s construction and the tools required will help you approach the process confidently.

In this article, we’ll explore the essential considerations and general steps involved in replacing the battery on a Bulova watch. Whether you’re a seasoned DIY enthusiast or a first-time watch owner, you’ll gain valuable insights to keep your timepiece ticking accurately for years to come.

Removing the Case Back

Accessing the battery compartment on a Bulova watch requires carefully removing the case back. Depending on the model, the case back may be a snap-off, screw-down, or secured with screws. Using the correct tools and techniques is essential to prevent damage.

For snap-off case backs, use a case knife or a thin, flat blade to gently pry open the back at the designated notch. Apply steady, controlled pressure to avoid bending or scratching the case. Screw-down backs require a case wrench or a specialized tool to unscrew the back by aligning the tool’s pins with the notches on the case back. If the case back is held by small screws, a precision screwdriver set will be necessary to remove them carefully.

It is advisable to work on a clean, soft surface such as a watchmaker’s mat or microfiber cloth to prevent scratches to the watch face and case. Additionally, ensure good lighting and magnification if needed, as the components are small and delicate.

Identifying and Removing the Old Battery

Once the case back is removed, the battery compartment will be visible. Bulova watches typically use button cell batteries, but the size and type can vary between models. Locate the battery, which is usually held in place by a clip or retainer.

To remove the old battery, gently lift the clip or retainer using non-metallic tweezers or a plastic tool to avoid short circuits. Carefully extract the battery, noting its orientation (positive and negative sides), as the replacement battery must be installed the same way.

Handle the battery with care and avoid touching it with bare hands, as oils and dirt can affect battery performance. Dispose of the old battery properly in accordance with local regulations.

Choosing the Correct Replacement Battery

Selecting the correct replacement battery is crucial to ensure the watch functions properly and maintains its water resistance. The battery type is often indicated on the old battery itself or in the watch’s user manual.

Common Bulova watch batteries include silver oxide button cells such as SR626SW, SR621SW, or SR920SW, among others. Lithium batteries may be used in some models, so confirm the exact type before purchase.

Consulting the following table can help identify the correct battery for your Bulova watch model:

Bulova Model Range Battery Type Common Battery Code Voltage
Classic Analog Watches Silver Oxide SR626SW 1.55 V
Chronograph Models Silver Oxide SR920SW 1.55 V
Marine Star Series Lithium CR2016 3 V
Automatic and Mechanical (Battery Not Required) N/A N/A N/A

If uncertain, consult a professional watch technician or authorized Bulova service center to avoid damage.

Installing the New Battery

Before installing the new battery, clean the battery compartment with a dry, lint-free cloth or a soft brush to remove any debris or corrosion. Using non-metallic tweezers, position the new battery in the same orientation as the old one, ensuring the positive (+) side aligns correctly according to the markings.

Once the battery is seated, carefully replace the clip or retainer to secure the battery in place. Avoid applying excessive force, which could damage internal components.

After the battery installation, briefly check the watch to confirm it is running correctly. Adjust the time if necessary using the crown.

Reassembling the Watch

Reattaching the case back is the final step to complete the battery replacement. For snap-off backs, align the case back correctly and press it firmly until it snaps into place. A watch press tool can be used to evenly apply pressure without damaging the watch.

Screw-down case backs must be screwed back in using the case wrench, ensuring they are tight enough to maintain water resistance but not over-tightened. For cases secured by screws, replace and tighten them evenly to avoid warping the case back.

After reassembly, test the watch functions and confirm the timekeeping is accurate. If the watch includes water resistance features, consider having it pressure tested by a professional to ensure the seals remain intact after battery replacement.

Precautions and Tips for Battery Replacement
