Learning how to replace Bulova watch battery yourself can save you a trip to the jeweler and get your favorite timepiece ticking again quickly. When replacing a Bulova watch battery, take note of the battery’s orientation before removing the old one. This simple tip is the key to a smooth process and prevents frustrating mistakes.
This guide provides clear, step-by-step instructions for replacing the battery in most Bulova watches. We’ll cover the tools you need, safety precautions, and how to handle common issues. With a little care, you can complete this task in just a few minutes.
How To Replace Bulova Watch Battery
Replacing the battery in your Bulova watch involves a few precise steps. The main goal is to open the case back, swap the old battery for a new one, and reseal the watch without damaging any components. Always work on a clean, well-lit surface and handle all parts gently.
Before you start, it’s crucial to identify your watch’s case back type. Bulova uses several styles, and the opening method varies for each. Using the wrong technique can scratch the watch or harm the mechanism inside.
Essential Tools And Supplies You Will Need
Gathering the right tools before you begin is essential for a successful battery replacement. Using improper tools is a common cause of damage. Here is a list of what you should have ready:
- A set of precision screwdrivers (often JIS standard).
- A case back opener tool (for screw-down backs) or a case knife (for snap-off backs).
- A pair of non-magnetic tweezers or plastic tweezers.
- A fresh watch battery. The number is usually printed on the old battery (e.g., 371, 395).
- A soft cloth or watch mat to protect the watch crystal and case.
- A magnifying glass or loupe for seeing small components.
- Compressed air or a soft brush to remove any dust.
Investing in a basic watch repair kit is often cheaper than a single professional battery replacement and gives you the tools for future needs. Ensure your workspace is free of clutter and has good lighting to see the tiny parts clearly.
Identifying Your Bulova Watch Case Back Type
The first real step is to determine how your watch’s back is secured. There are three primary types of case backs used by Bulova, and each requires a different opening method. Look closely at the back of your watch to see which one you have.
Screw-Down Case Back
This back has small notches or indentations around its edge. It threads onto the watch case. You will need a case back wrench or a specific multi-tool that fits these notches to unscrew it. Do not attempt to use pliers, as they will mar the metal.
Snap-Off Case Back
A snap-off back fits snugly into a groove in the watch case and is held in place by pressure. It often has a slight lip. You will insert a case knife or a thin pry tool into this seam to carefully lever the back off. This type is common on many dress and classic Bulova models.
Screwed Case Back
Some watches have a plain back secured by several tiny screws around the perimeter. You must use a precision screwdriver that fits the screw heads perfectly to remove them. Keep the screws in a small container so they don’t get lost.
If you are unsure, searching your Bulova’s model number online can often provide specifications or videos showing the correct case back style.
Step-by-Step Battery Replacement Process
Once you have your tools and have identified the case back, you can proceed with the replacement. Follow these steps in order to avoid errors.
Step 1: Opening the Watch Case Back
- Place the watch face-down on the soft cloth to prevent scratches.
- For a screw-down back: Select the correct pins on your case back wrench to fit the notches. Apply steady, even pressure to turn the back counter-clockwise until it loosens.
- For a snap-off back: Locate the slight groove. Insert your case knife gently and twist slightly to pry the back up. Move to a different point and repeat until the back pops off. Avoid forcing it.
- For a screwed case back: Use your precision screwdriver to remove each screw. Place them safely aside, then lift the case back off.
Step 2: Removing the Old Battery
With the case back removed, you will see the watch movement. The battery is a small, silver disc held in a compartment by a tiny metal clamp.
- Use your tweezers to carefully note the battery’s position. The side facing up is usually the positive (+) side.
- Look for the small metal retaining clip. You may need to gently slide it to the side or lift one end with your screwdriver to release the battery.
- Once the clip is moved, the battery should be loose. Use non-magnetic tweezers to lift the battery straight out. If it’s stuck, gently nudge it from the side.
- Set the old battery aside. It’s a good idea to confirm the battery number (e.g., SR626SW) matches your new one before proceeding.
Step 3: Inserting the New Battery
This is the most critical step. Inserting the battery incorrectly can prevent the watch from working.
- Take your new battery with the tweezers. Avoid touching the battery faces with your fingers, as skin oils can affect performance.
- Observe the battery compartment. There is usually a positive (+) sign or marking indicating where the positive side of the battery should go.
- Place the new battery into the compartment with the correct orientation, matching the old battery’s position.
- Secure the battery by moving the metal retaining clip back into its original position over the edge of the battery. You should hear or feel a slight click.
Step 4: Resealing the Watch Case
Before closing the watch, take a moment to check for dust inside the case. Use a blast of compressed air or a soft brush to gently remove any particles.
- For a snap-off back: Align the back with the groove on the watch case. Apply even pressure with the palm of your hand or a case press tool until it snaps securely into place.
- For a screw-down back: Carefully thread the back onto the case by hand first to avoid cross-threading. Then, use your case back wrench to tighten it snugly, but do not overtighten.
- For a screwed case back: Place the back on and re-insert all the screws. Tighten them gently and evenly in a cross pattern.
Once the back is secure, set the time and date on your watch. If the watch does not start immediately, gently tap the case on your palm; this can sometimes jostle the mechanism to start.
Safety Tips And Common Mistakes To Avoid
Working on a delicate watch requires patience. Rushing can lead to permenant damage. Here are key safety tips and pitfalls to steer clear of.
- Always work in a clean area. A lost screw or a speck of dust inside the case can stop the watch.
- Never use magnetic tools near the watch movement. Magnetism can disrupt the delicate mechanics.
- Avoid touching the movement or the circuit with your fingers. Use tweezers instead.
- Do not force any component. If something isn’t moving easily, stop and reassess.
- Ensure the gasket (the small rubber ring on the case back) is clean and seated properly to maintain water resistance. If it’s damaged, it should be replaced.
- Using the wrong battery size or type can lead to leakage or damage. Double-check the code.
If you encounter significant resistance or see any damaged parts, it is best to stop and consult a professional watchmaker. Some newer Bulova models with advanced features may require special handling.
Troubleshooting: If Your Watch Still Doesn’t Work
If you’ve replaced the battery but your Bulova watch remains inactive, don’t worry. Several simple issues could be the cause. Try these troubleshooting steps before assuming the worst.
- Check the battery orientation again. This is the most common mistake. The positive side must match the marking in the compartment.
- Ensure the battery is fully seated and the retaining clip is secure. A loose battery won’t make contact.
- Inspect for corrosion. If the old battery leaked, it may have left corrosive residue on the contacts. This can be carefully cleaned with a cotton swab dipped in isopropyl alcohol.
- The watch may have a “contact spring” that needs to be reset. Sometimes, removing the battery resets a power-saving feature; consult your manual.
- It’s possible the new battery itself is dead. This is rare but can happen. Test it with a battery tester if you have one.
If none of these steps work, the issue may be with the watch movement itself, such as a damaged circuit or coil. At this point, seeking professional service is the recommended course of action.
When To Seek Professional Help
While many battery replacements are straightforward, some situations warrant a visit to a watch repair specialist. Knowing when to call a professional can save you from causing expensive damage.
- If your watch is a high-value, vintage, or complex model like a Bulova Precisionist or a chronograph.
- If the case back is extremely tight, stripped, or shows signs of previous tampering.
- When the watch is supposed to be water-resistant. Resealing it properly requires specific tools and pressure testing to guarantee integrity.
- If you see any damage inside the watch, such as broken gears, loose screws, or significant corrosion.
- If you simply do not feel comfortable proceeding after reading the instructions. There’s no shame in opting for professional service.
A professional can also perform a quick clean and check the watch’s overall health, which is a good idea every few years anyway.
