Opening the watch case

Most Bulova watches use a screw-back case, which means the back cover is held on by a ring of small screws rather than a snap-on design. You will need a small screwdriver — typically a Phillips head, though some models use a flathead — and a clean, flat work surface. Place the watch face-down on a soft cloth or towel so you do not scratch the crystal.

Locate the screws around the edge of the case back. They are usually evenly spaced and quite small. Using steady, gentle pressure, turn each screw counterclockwise until all are loose enough to remove by hand. Do not force them; if a screw resists, you may be using the wrong screwdriver size. Once all screws are out, set them in a small container so they do not roll away. Carefully lift the case back straight up and away from the watch body.

Key Takeaways

  • Bulova watches almost always have screw-back cases that require a small Phillips or flathead screwdriver to open.
  • The battery sits in a metal holder called a battery clip or retainer, which you must lift or unclip before the old battery comes out.
  • Write down the battery type number (usually printed on the old battery itself) before you buy a replacement, because Bulova uses several different sizes.
  • When you reinstall the case back, tighten the screws in a crisscross pattern — opposite screws alternately — so the seal stays even.

Identifying and removing the old battery

Once the case back is off, you will see the watch movement — the internal mechanism — and the battery sitting in a metal holder. The battery is typically a small, flat, coin-shaped cell. Most Bulova watches use a battery type that starts with "3" or "3V" (such as 3V2032 or 3V2016), though some older models use different types.

Before you remove the old battery, look at the top or side of the battery itself. The type number is usually printed there. Write this number down or take a photo with your phone. This is the information you will need when you buy the replacement. The battery sits under a metal clip or retainer. Gently lift or unclip this holder away from the battery, then lift the battery straight out of its seat. Do not force it; if it seems stuck, make sure the clip is fully released.

Buying the correct replacement battery

Take the battery type number you wrote down to a pharmacy, jewelry store, or electronics retailer that sells watch batteries. Common Bulova battery types include 3V2032, 3V2016, 3V2025, and SR626W, but your specific model may use a different one. Do not guess or buy a battery that looks similar — the wrong size will not fit, or it may fit but not power the watch correctly.

If you cannot find the type number on the old battery, you can also bring the old battery itself to the store and ask the staff to match it. Many jewelry stores and pharmacies with watch departments keep several battery types in stock and can sell you the right one on the spot. The cost is usually between two and eight dollars.

Installing the new battery

Before you insert the new battery, check that the metal clip or retainer is still in its open position. Hold the new battery with the positive side (marked with a + or the flat side) facing up, away from the watch movement. Carefully place the battery into the seat where the old one was. Make sure it sits flat and level in the holder.

Once the battery is in place, gently press the metal clip back down over the battery to hold it find. You should hear or feel a small click as the clip locks into place. Do not force the clip; it should move smoothly. If it does not, lift it again and check that the battery is sitting flat. The clip should rest snugly but not require pressure to stay down.

Sealing the case back and testing

Before you screw the case back on, wipe the inside of the case back and the rim of the watch body with a clean, dry cloth. Any dust or debris trapped between them can prevent a watertight seal. Line up the case back with the watch body so the screw holes align, then insert all the screws by hand first.

Once all screws are started, tighten them in a crisscross pattern — tighten one screw, then the one directly across from it, then move to the next pair. This ensures the case back seats evenly and the gasket (the rubber seal) compresses uniformly. Tighten each screw firmly but do not over-tighten, which can strip the threads or crack the case back. The screws should be snug enough that the case back does not move, but you should not need to force them.

Once the case back is sealed, flip the watch over and check that it is working. The second hand should be moving. If it is not, the battery may not be making contact with the clip, or you may have installed it upside down. If this happens, open the case back again and check the battery position and the clip contact.

When to take your watch to a professional

If the watch does not start after you install the new battery, or if you feel resistance when opening the case back, stop and take the watch to a jewelry store or watch repair shop. Some Bulova models have sealed cases that require special tools to open safely, and forcing them can damage the gasket or crack the case. A professional can also test the movement to make sure no other parts are damaged.

If your watch is a vintage Bulova or has sentimental value, consider having a professional handle the battery change from the start. The cost of a professional battery change is usually ten to twenty dollars, and it protects your watch from accidental damage.

Frequently Asked Questions

Can I use any battery that fits in the space?

No. The battery type number matters because different batteries have different voltages and capacities. Using the wrong type can damage the watch movement or cause it to run fast or slow. Always match the type number printed on the old battery.

What if I lose one of the screws?

Take the watch to a jewelry store or watch repair shop with the remaining screws. They can usually match the size and replace the lost one for a few dollars. Do not try to use a different screw, because it may not fit properly or may be the wrong length.

How often do Bulova watch batteries need to be changed?

Most Bulova batteries last two to three years with normal daily wear. If you wear the watch less frequently, the battery may last longer. When the watch stops, the battery is dead and needs to be replaced.

Is the gasket under the case back something I need to replace?

Not usually. The gasket is a rubber seal that keeps water out. If it looks dry, cracked, or flattened, a professional can replace it when they change the battery. For a straightforward battery change on a watch you do not wear in water, the existing gasket is usually fine.

What should I do with the old battery?

Do not throw it in the trash. Take it to a pharmacy, electronics store, or recycling center that accepts batteries. Many retailers that sell watch batteries also collect old ones for recycling at no charge.
