In the following sections, you’ll discover an overview of what’s involved in changing a Bulova watch battery, including tips on identifying the correct battery type and safely opening your watch case. Whether you’re a seasoned watch enthusiast or a first-time DIYer, this guide will equip you with the knowledge to keep your Bulova running smoothly and accurately.
Removing the Back Case of a Bulova Watch
To access the battery compartment in a Bulova watch, the back case must be carefully removed. The method depends on the specific model, but most Bulova watches feature either a snap-back or screw-back case. Using the proper tools and techniques is essential to avoid damage.
For snap-back cases, a case knife or a thin, flat tool is used to gently pry open the back. Locate the small indentation or notch on the edge of the case back. Insert the tool there and apply steady, gentle pressure until the back pops off. Avoid using excessive force to prevent scratching or bending the case.
Screw-back cases require a case wrench or a specialized watch case opener. Align the tool’s pins with the corresponding notches on the back cover, then turn counterclockwise to unscrew. This method offers a more secure closure but must be handled cautiously to avoid stripping the notches.
Before beginning, ensure the workspace is clean and well-lit. It is advisable to place a soft cloth underneath the watch to protect the crystal and casing from accidental scratches.
Identifying and Removing the Old Battery
Once the back case is removed, the battery will be visible, typically secured by a clip or small retaining screw. Identify the battery type by checking the printed number on the battery itself, as Bulova watches use specific battery models depending on the movement.
To remove the battery safely:
- Use plastic or non-metallic tweezers to avoid short-circuiting.
- If a retaining clip is present, gently lift or unscrew it.
- Carefully extract the battery, noting its orientation for correct replacement.
Avoid touching other internal components, as they are delicate and can be easily damaged. If unsure about the battery type, refer to the watch’s manual or check the markings on the battery.
Selecting the Correct Replacement Battery
Choosing the right battery is critical for the proper functioning of your Bulova watch. Using an incorrect battery can cause malfunction or damage to the movement.
Common battery types used in Bulova watches include silver oxide and lithium variants. Silver oxide batteries are preferred for their stable voltage output, whereas lithium batteries offer longer life but must be matched precisely to the watch’s specifications.
Below is a table with common Bulova battery models and their corresponding types and approximate life expectancy:
| Battery Model | Type | Voltage | Approximate Life | Common Usage |
|---|---|---|---|---|
| SR626SW (377) | Silver Oxide | 1.55V | 1-2 years | Analog Quartz Watches |
| SR920SW (371) | Silver Oxide | 1.55V | 2-3 years | Chronograph Watches |
| CR2016 | Lithium | 3V | 2-3 years | Digital Watches |
Always verify the battery number on the old battery or consult the Bulova watch manual to ensure compatibility.
Installing the New Battery and Reassembling the Watch
After selecting the correct replacement battery, installation requires precision and care. Insert the new battery in the exact orientation as the previous one, typically with the positive (+) side facing up. Using plastic tweezers or gloves prevents contamination from oils or dirt.
If a retaining clip or screw was removed, replace it securely without over-tightening, which could damage the battery or internal components. Double-check that the battery sits flush and is making proper contact with the terminals.
Before closing the back case, it is recommended to test the watch to confirm the new battery is functioning correctly. Set the time and observe the second hand or digital display for movement.
When replacing the back case:
- For snap-back cases, align the case back carefully and press firmly until it snaps into place. A case press tool can be used to ensure even pressure and avoid damage.
- For screw-back cases, align the threads and turn clockwise using the case wrench until snug. Avoid over-tightening, which may strip threads or damage the gasket.
Ensure the case back is sealed properly to maintain water resistance. If the watch contains a gasket or rubber seal, inspect it for damage and replace if necessary to preserve waterproof properties.
Tools Recommended for Battery Replacement
Having the correct tools improves efficiency and reduces the risk of damaging the watch. Essential tools include:
- Case knife or case opener tool for snap-back cases
- Case wrench or adjustable case opener for screw-back cases
- Plastic tweezers to handle batteries safely
- Small screwdriver set for retaining clips or screws
- Soft cloth or pad to protect the watch during work
- Case press tool for resealing snap-back cases (optional but recommended)
Using these tools will facilitate a professional and safe battery replacement process.
Identifying the Battery Type for Your Bulova Watch
Before attempting to change the battery, it is essential to determine the correct battery type for your specific Bulova watch model. Using the wrong battery can damage the watch or cause improper functioning.
Most Bulova watches use standard button cell batteries, but the exact model varies. These batteries are typically silver oxide or lithium types, chosen for their stable voltage and long life.
To identify the battery type:
- Check the watch’s user manual or warranty card for battery specifications.
- Look for any markings on the back case of the watch, which may indicate the battery model.
- If neither is available, consult Bulova’s official website or authorized service centers with your watch’s serial number.
- Remove the battery carefully and inspect the existing battery for a model number if you are confident in handling the watch.
| Common Bulova Battery Models | Battery Type | Typical Voltage | Watch Series Examples |
|---|---|---|---|
| SR626SW (377) | Silver Oxide | 1.55V | Classic analog models |
| SR920SW (371) | Silver Oxide | 1.55V | Chronograph and multifunction watches |
| CR2032 | Lithium | 3V | Digital and some specialty watches |
