You can replace most Invicta watch batteries yourself with a case opener and a fresh battery
Invicta watches use standard coin-cell batteries that you can buy at any drugstore or hardware store for $3 to $8. The job takes about 10 minutes and requires only two tools: a watch case opener (also called a case back remover) and a small flathead screwdriver. You do not need to send the watch to a jeweler unless the case is sealed or the battery compartment is damaged.
The most common Invicta batteries are the SR626SW (silver oxide) and the LR626 (alkaline). Check your watch manual or the old battery itself to find the exact model number before you buy a replacement. If you cannot find the number, take a photo of the old battery and show it to the store clerk—they can match it for you.
Key Takeaways
- Most Invicta watches have a removable case back held on by a single screw or a snap ring, not a sealed case.
- You need a watch case opener (a flat metal tool with a slot) and a small flathead screwdriver to open the case and remove the battery.
- The battery sits in a metal holder called a battery clip; slide it gently to the side to release the battery, then drop in the new one.
- Avoid touching the new battery with bare fingers, because skin oils can shorten its life.
- If the case back is stuck or the battery clip is bent, stop and take the watch to a jeweler rather than forcing it.
Gather your tools and the correct replacement battery
Before you open the watch, buy the right battery. Look at your Invicta manual, the original box, or the watch itself for the battery model number. Common Invicta batteries include SR626SW, SR927SW, SR920SW, and LR626. If you cannot find the number, remove the old battery first (see the next section) and take it to a pharmacy, hardware store, or watch repair shop to match it.
You will also need a watch case opener. These cost $5 to $15 and look like a flat metal tool with a slot or notch at the end. You can buy one at any jewelry supply store, online, or sometimes at a watch counter in a department store. A small flathead screwdriver (size 0 or 00) is also helpful for prying the case back off if it has a screw, though many Invicta cases snap on without fasteners.
Lay out a clean, flat surface—a kitchen towel or a white paper plate works well. This keeps the small parts visible and prevents them from rolling away. Wash your hands before you start, because skin oils can damage the battery and reduce its lifespan.
Open the case back and locate the battery
Turn the watch over so you are looking at the back. Most Invicta watches have either a screw-on case back or a snap-on case back. If you see a small screw, use your flathead screwdriver to remove it—turn counterclockwise. If there is no screw, the case back snaps on, and you will use the case opener to pry it off.
For a snap-on case back, insert the slot of the watch case opener into the small notch or groove on the edge of the case back. Gently twist the opener to the side, as if you were opening a paint can. The case back should pop off. Do not force it—if it does not move after light pressure, the watch may have a sealed case, and you should take it to a jeweler.
Once the case back is off, you will see the battery sitting in a metal clip or holder. The battery is usually round and silver or gold colored. Do not touch the face of the battery with your bare fingers. If you need to pick it up, hold it by the edge only.
Remove the old battery and install the new one
The battery sits under a metal clip that holds it in place. To release it, gently slide the clip to the side using your small flathead screwdriver or a plastic tool. The clip will move just enough to free the battery. Once the clip is out of the way, the old battery should lift out easily. If it does not, do not pry—the clip may be bent, and forcing it can damage the watch.
Before you insert the new battery, check that the battery compartment is clean and dry. If you see any corrosion (a white or green crusty substance), wipe it gently with a dry cotton swab. Do not use water or cleaning solution.
Slide the new battery into the compartment with the positive side (marked with a + or the flat side) facing up. This is the side that was facing up on the old battery. Slide the metal clip back over the battery until it clicks or sits snugly. The battery should not move when you gently shake the watch.
Close the case back and test the watch
If the case back has a screw, line it up with the hole and turn it clockwise with your flathead screwdriver. Tighten it snugly but do not over-tighten, which can strip the threads. If the case back snaps on, press it firmly back onto the watch body until you hear or feel a click. It should sit flush with the case—no gaps or edges sticking up.
Once the case is closed, press the crown (the knob on the side) or any buttons to see if the watch turns on or responds. If the watch has a second hand, it should start ticking. If nothing happens, the battery may be installed upside down. Open the case back again and flip the battery so the positive side faces up.
If the watch still does not work after you flip the battery, the old battery may have been dead for a long time and the watch may need a jeweler's attention. Do not keep opening and closing the case, as this can damage the gasket (the rubber seal that keeps water out).
Common mistakes and when to stop
The most common error is installing the battery upside down. If the watch does not work after you close the case, open it once more and check that the positive side of the battery faces up. This is usually the flat side, and it matches the side that faced up on the old battery.
Another mistake is touching the battery face with your fingers. Skin oils can create a thin film that blocks the electrical connection. If you have already touched the new battery, wipe it gently with a clean, dry cloth before installing it.
Do not force the case back open if it is stuck. Forcing it can crack the plastic or damage the threads. If the case back will not budge after gentle pressure, or if the battery clip is bent or corroded, take the watch to a jeweler. The cost of a professional battery replacement is usually $10 to $25, which is worth it to avoid damaging the watch.
How to know if your Invicta battery needs replacing
The most obvious sign is that the watch stops running or loses time. Some Invicta watches have a second hand that ticks once per second when the battery is good, but slows to once every few seconds when the battery is dying. This is called the end-of-life indicator, and it tells you to replace the battery soon.
If the watch has not been worn in months, the battery may have drained even if the watch was working before. Leaving a watch unworn for a year or more can cause the battery to lose charge. In that case, a fresh battery will usually restore the watch to full function.
If the watch is wet or you notice corrosion inside the case, the battery may have leaked. Corrosion looks like white, green, or blue crusty deposits around the battery or clip. If you see corrosion, clean it gently with a dry cotton swab and install a fresh battery. If the corrosion is heavy or the watch has been submerged, take it to a jeweler to check the gasket and seals.
Frequently Asked Questions
What if the case back is glued or sealed?
Some Invicta sports watches and dive watches have sealed case backs that are not meant to be opened at home. If the case opener does not grip or the case back will not budge after gentle pressure, the watch is sealed. Take it to a jeweler or an authorized Invicta service center. Forcing a sealed case can crack it and ruin the water resistance.
Can I use any battery, or does it have to be an Invicta brand?
You do not need an Invicta brand battery. Any battery with the same model number (like SR626SW or LR626) will work. Pharmacy and hardware store batteries are the same quality as branded ones and cost less. Just match the model number exactly.
How long does a new battery last?
Most Invicta watch batteries last two to three years with normal daily wear. Batteries in watches that sit unworn for long periods may last longer because they drain more slowly. If your watch stops after only a few months, the battery may be defective, or the watch may have an internal problem that a jeweler should check.
Do I need to waterproof the watch after replacing the battery?
If your Invicta is water-resistant and you only removed a screw-on case back, the gasket should still seal properly when you close it. However, if you opened a snap-on case back, the gasket may have shifted slightly. If your watch is rated for diving or deep water, have a jeweler test the water resistance after you replace the battery. For casual water resistance (splash-proof), a home battery replacement is usually fine.
What should I do with the old battery?
Do not throw a used battery in the trash. Take it to a pharmacy, hardware store, or recycling center that accepts batteries. Many stores have battery recycling bins near the checkout. Batteries contain metals that can harm the environment if they end up in a landfill.
