You can replace a Nixon watch battery yourself with basic tools, or take it to a watch repair shop if you're uncomfortable opening the case

Most Nixon watches use a standard coin-cell battery (usually CR2032, CR2025, or SR626SW) that you can swap out in about five minutes if you have a case opener tool. The process is straightforward: open the case back, note which battery is inside, remove it, and drop in a fresh one of the same type. If you don't want to do it yourself, a watch repair shop or jeweler will do it for $10 to $25, usually while you wait.

The main decision is whether to buy the tool and do it at home, or pay someone else. A case opener costs $8 to $15 and works on any watch with a screw-off back. If you only have one Nixon watch and no plans to replace batteries again, a repair shop makes sense. If you have multiple watches or want to keep the cost down long-term, the tool pays for itself quickly.

Key Takeaways

  • Nixon watches almost always use a standard coin-cell battery that you can buy at any pharmacy, supermarket, or online retailer for $3 to $8.
  • You need a case opener tool (also called a case back opener or watch opener) to unscrew the back of the watch; they cost $8 to $15 and work on any screw-back watch.
  • Write down or photograph the battery type before you remove the old one, because the number printed on it (like CR2032) tells you exactly what to buy as a replacement.
  • A watch repair shop or jeweler can replace the battery for $10 to $25 if you prefer not to open the watch yourself.

Finding out what battery your Nixon uses

The battery type is printed on the battery itself, so you need to open the watch to read it. Look at the back of your Nixon watch for a seam running around the edge—that's where the case back screws on. Some Nixon watches have a smooth back with no visible seam; those use a different opening method (see the section below on press-fit backs).

Before you buy a case opener, you can also check the Nixon website or your watch manual if you still have it. Many Nixon models list the battery type in the specs. You can also email Nixon's customer service with your watch model number and they will tell you the battery type. That way you know what to buy before you commit to opening the case.

Opening a screw-back case and removing the battery

A case opener tool has a handle with two or three metal prongs that fit into the notches on the watch case back. Position the prongs into the notches (they are usually evenly spaced around the edge), then turn the handle counterclockwise. The back will unscrew—go slowly so you don't strip the threads. Once it's loose, unscrew it the rest of the way by hand.

Inside you will see the battery sitting in a small metal holder or clip. Before you touch anything, take a photo of the battery so you can see the type number clearly. Then gently pry or lift the battery out using a plastic spoon, plastic tweezers, or the edge of a plastic card. Do not use metal tools directly on the battery, because metal can cause a short circuit. If the battery is held down by a metal clip, lift the clip gently first, then remove the battery.

Once the old battery is out, note the type number (it will be something like CR2032 or SR626SW). That is the number you need when you buy the replacement. Drop the new battery in with the positive side facing up (the side with the + symbol or the flat side, depending on the battery type). Close the metal clip if there is one, then screw the case back on by hand first, then tighten it with the case opener tool turning clockwise.

What to do if your Nixon has a press-fit back

Some Nixon watches, especially sports models and digital watches, have a case back that is pressed on rather than screwed. You will not see a seam or notches. These require a different tool called a case press or a specialized opener with a rubber pad.

If your watch has a press-fit back, a watch repair shop is the easiest option, because they have the right tool and can open it without risk of damage. Attempting to pry a press-fit back off with a screwdriver or knife can crack the case or scratch the watch. If you want to do it yourself, you can buy a case press tool for $20 to $40, but it is only worth it if you plan to service multiple watches.

Where to buy a replacement battery

Once you know the battery type, you can buy it at a pharmacy (CVS, Walgreens), a supermarket, a hardware store, or online. Prices are usually $3 to $8 per battery. Buy from a reputable seller so you know the battery is fresh—old batteries lose charge even if they have never been used. If you are buying online, check the expiration date in the product listing.

You can also buy batteries in bulk packs if you have multiple watches or want to keep spares on hand. A pack of five CR2032 batteries might cost $10 to $15, which works out to $2 to $3 per battery. Make sure you buy the exact type your watch needs; buying the wrong size will not work and the battery will not fit in the holder.

Tools you need and where to find them

For a screw-back watch, you need a case opener tool. These are sold under names like "watch case opener," "case back opener," or "watch opener." They cost $8 to $15 and are available at jewelry supply stores, online retailers, and some watch repair shops. You may also find them at hardware stores or tool sections of large retailers.

You will also want plastic tweezers or a plastic spoon to remove the battery—anything non-metal that will not scratch the inside of the watch or cause a short. A small flashlight or your phone's flashlight helps you see inside the case. That is all you need. Do not use a metal screwdriver or knife to pry the back open, because you can damage the threads or the case.

When to take your Nixon to a professional

Take your watch to a repair shop if the case back is stuck or will not unscrew, if you are uncomfortable opening the watch yourself, or if your Nixon has a press-fit back. A stuck back usually means the threads are corroded or the back was over-tightened at some point. Forcing it can strip the threads permanently. A professional has penetrating oil and the right leverage to open it safely.

You should also go to a professional if you notice water inside the case, corrosion around the battery holder, or any sign that the watch has been damaged. These are signs that the case seal may be compromised, and a professional can check the gasket and reseal the watch if needed. A watch repair shop or jeweler can handle all of this, and the cost is usually $15 to $40 depending on what needs to be done.

Frequently Asked Questions

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

Any CR2032 from a reputable brand will work. Duracell, Energizer, Maxell, and store brands are all fine. The important thing is that it is fresh and the correct type number. Avoid very cheap batteries from unknown sellers, because they may be old stock or counterfeit.

What if I put the battery in backwards?

The watch straightforward will not work. The battery holder is designed so the battery only fits one way, but if you force it, you can damage the contacts. If the watch does not turn on after you close it, open it again and check that the positive side (marked with a +) is facing up.

How long does a Nixon watch battery last?

Most coin-cell batteries last two to three years in a watch, depending on the watch model and how often you use it. Digital watches and watches with backlights drain batteries faster. If your battery dies much sooner, the watch may have a problem and should be checked by a professional.

Do I need to replace the gasket when I replace the battery?

No, the gasket (the rubber seal around the case back) does not need to be replaced every time you change the battery. If the gasket looks cracked, dried out, or damaged, have it replaced at a repair shop. Otherwise, just screw the back on and you are done.

What if I lose the old battery or cannot read the type number?

Contact Nixon customer service with your watch model number and they will tell you the battery type. You can also take the watch to a repair shop and they can identify it for you. Do not guess—buying the wrong size will waste money and the battery will not fit.
