You can replace a Citizen watch battery yourself with basic tools, or take it to a jeweler or Citizen service center

Replacing a Citizen watch battery is straightforward if you have a case opener and a small screwdriver — tools that cost less than $10 together. Most Citizen watches use a standard battery (usually CR2032, CR2025, or SR626SW) that you can buy at any drugstore for $3 to $8. The job takes 10 to 15 minutes if you work carefully.

If you would rather not open the watch yourself, a jewelry store or Citizen authorized service center will do it for $15 to $40, including the battery. This is the safer choice if your watch is valuable, still under warranty, or if you are not confident with small tools.

Key Takeaways

  • Citizen watches typically use common coin-cell batteries like CR2032 or SR626SW that are sold at drugstores and online retailers.
  • You need a case opener (a flat tool that pries the back off) and a small screwdriver to do the job yourself, and the whole process takes about 15 minutes.
  • If you open the watch yourself, note the battery type and orientation before you remove it so you install the new one the same way.
  • A jewelry store or Citizen service center will replace the battery for a fee if you prefer not to open the watch yourself.
  • Citizen watches are often water-resistant, so if you open the case yourself, check whether your model needs a new gasket when you close it again.

Finding out what battery your Citizen watch uses

The battery type is printed on the old battery itself once you open the case. Before you buy a replacement, you need to know whether your watch holds a CR2032, CR2025, SR626SW, or another type — they are not interchangeable. If you do not want to open the watch yet, you can also check the Citizen website by model number, or call a Citizen service center and give them your watch model.

The model number is usually on the back of the watch case, stamped or printed near the edge. Write it down and search for it on Citizen's site or on the retailer where you bought the watch. The product page often lists the battery type in the specifications. You can also take a photo of the case back and show it to a jewelry store — they can usually identify the battery type from the model number.

Tools and materials you will need

A case opener (also called a case back remover) is the most important tool. It is a flat metal pry tool with a notch that fits into the groove on the back of the watch case. You can buy one for $5 to $15 at any jewelry supply store, online, or sometimes at a hardware store. Do not use a flathead screwdriver or a knife — they will slip and scratch the case.

You will also need a small Phillips or flathead screwdriver (depending on your watch model) to remove the battery holder or clip, and a new battery of the correct type. Have a clean, lint-free cloth or paper towel ready so you do not get fingerprints on the inside of the case or the new battery. Some people wear cotton gloves to avoid skin oils on the battery contacts, which can reduce battery life.

Step-by-step: opening the case and removing the old battery

Lay the watch face-down on a soft surface like a cloth or towel so the crystal does not get scratched. Locate the groove or notch on the edge of the case back. Insert the case opener into the groove and gently twist or pry upward. The case back should pop off — if it does not budge after light pressure, try a different spot on the groove. Do not force it, or you may crack the case.

Once the case is open, look at how the battery sits. Most Citizen watches hold the battery under a small metal clip or in a plastic holder. Note which side faces up (the + or – marking, if visible). If there is a clip, use your small screwdriver to loosen the screw holding it, then lift the clip away. Carefully remove the old battery and set it aside. Do not touch the battery contacts inside the case with your bare fingers.

Before you install the new battery, check inside the case for a rubber gasket or seal around the edge. If your watch is water-resistant, this gasket keeps water out. If it looks cracked, dried out, or is missing, you may need a replacement gasket — Citizen service centers stock them, or you can order one online by model number. Replacing a gasket costs $5 to $15 and takes a few minutes.

Installing the new battery and closing the case

Take the new battery and orient it the same way the old one was facing — usually with the + side up, but check the old battery or the holder to be sure. Slide the new battery into place. If there is a metal clip, position it over the battery and tighten the screw with your small screwdriver. Do not overtighten — snug is enough.

Before you close the case, make sure the gasket is clean and seated properly in its groove. If it has shifted, gently press it back into place. Now align the case back with the watch body and press down firmly all around the edge until you hear or feel a click. The case should sit flush with no gaps. If it does not close smoothly, remove it and check that the gasket is not pinched or twisted.

Once the case is closed, press the crown (the knob on the side) a few times to make sure the watch still works. If it does not, open the case again and check that the battery is making contact with both the positive and negative terminals inside. This is the most common reason a watch does not start after a battery replacement.

When to take your watch to a professional instead

If your Citizen watch is very old, rare, or has sentimental value, a Citizen authorized service center is the safer choice. They have the right tools and can check the gasket and other seals while they are inside. If your watch is still under warranty, opening it yourself may void the warranty — check your paperwork first.

A jewelry store that services watches can also do the job quickly. Call ahead and ask the price — most charge $15 to $40 including the battery. Turnaround is usually same-day or next-day. If you are not confident with small tools or do not want to risk damaging the case, this is money well spent.

Troubleshooting: watch does not work after battery replacement

If the watch does not start after you close the case, open it again and check that the battery is touching both the positive and negative contacts. Sometimes a battery sits slightly crooked and does not make full contact. Remove it, clean the contacts with a dry cloth, and reinstall it, making sure it sits flat.

If the watch still does not work, the old battery may have been leaking and corroded the contacts inside. This is rare but happens. If you see white or blue-green crusty deposits on the contacts, try cleaning them gently with a dry cotton swab. If that does not work, the watch may need professional service to replace the contacts or circuit board — take it to a Citizen service center.

Another possibility is that you installed the battery upside down. Remove it and check the + and – markings on both the battery and the holder. They should match. Also make sure you bought the correct battery type for your model — a CR2032 will not work in a watch designed for a CR2025.

Frequently Asked Questions

Can I use any CR2032 battery, or does it have to be a Citizen brand?

Any CR2032 battery from any brand will work in your Citizen watch, as long as it is the correct type for your model. Duracell, Energizer, and store brands all work the same way. The battery itself does not know what watch it is in. Buy from a reputable source so you know it is fresh.

What if I lose the gasket when I open the case?

If the gasket falls out or gets damaged, order a replacement by your watch model number from Citizen or an online watch parts retailer. They cost $5 to $15. Until you install a new one, your watch will not be water-resistant, so avoid getting it wet. A Citizen service center can also install a new gasket for you.

How often do Citizen watch batteries need replacing?

Most Citizen watch batteries last two to three years with normal wear. Some last longer, some shorter, depending on the watch model and how often you use it. When the watch stops, the battery is dead and needs replacing. There is no way to predict exactly when it will happen.

Is it safe to open a water-resistant Citizen watch myself?

Yes, as long as you work carefully and make sure the gasket is clean and properly seated when you close it again. Water-resistant does not mean waterproof — it means the watch can handle splashes and brief immersion. If you damage the gasket or do not close the case properly, water can get inside. If you are unsure, take it to a professional.

What should I do with the old battery?

Coin-cell batteries contain small amounts of mercury or other metals and should not go in the trash. Take the old battery to a drugstore, electronics retailer, or hazardous waste collection site in your area. Many places that sell batteries will take old ones back for free.
