You can change a Fossil watch battery yourself with basic tools, or take it to a jeweler or Fossil store
A Fossil watch battery typically lasts two to three years before it stops holding a charge. When your watch stops, you have two paths: open it yourself with a case opener and tweezers, or pay a jeweler or Fossil retailer to do it. The DIY route costs $10 to $20 in tools and $5 to $15 for the replacement battery. A jeweler or Fossil store will charge $20 to $50 in labor, depending on your location and whether they stock the exact battery your model needs.
The battery type varies by watch model — Fossil makes watches with quartz movements that use coin-cell batteries, most commonly CR2032, CR2016, or SR626SW. Before you start, you need to know which battery your watch takes. Check the Fossil website with your watch model number, look at the back of the watch case if the battery type is printed there, or ask a jeweler to identify it without opening the case.
Key Takeaways
- Fossil watch batteries are coin-cell types, usually CR2032 or CR2016, and cost $5 to $15 when bought separately.
- A case opener tool (under $15) and tweezers are the only tools you need to change the battery yourself.
- The back of the watch case usually has a small notch or slot where you insert the case opener to pry it open.
- Once the case is open, note how the battery sits before you remove it, then drop the new battery in the same way and close the case.
- If the case will not open or you are uncomfortable working on your watch, a jeweler or Fossil store can do it in one visit.
Find your watch model and battery type before you start
Open the Fossil website and search for your watch by model number. The model number is usually printed on the back of the case or on the original box. Once you find your watch, the product page lists the battery type under specifications or technical details.
If you cannot find the model number or the website does not list it, take a photo of the back of your watch and bring it to a Fossil store or a local jeweler. They can identify the battery type by looking at the movement inside without charging you. Write down the battery type — CR2032, CR2016, SR626SW, or whatever it says — before you leave.
Buy the replacement battery from a pharmacy, electronics store, or online. A single coin-cell battery costs $3 to $8. Buy two so you have a spare, since they are inexpensive and you may need one again in a few years.
Gather the tools: case opener, tweezers, and a clean surface
You need a watch case opener — a small flat tool with a notch at the end, designed to fit into the slot on the back of the watch case. They cost $8 to $15 on Amazon or at jewelry supply stores. Do not use a regular flathead screwdriver; it is too thick and will damage the case.
You also need tweezers to handle the battery without touching it with your fingers. Oils from your skin can corrode the battery contacts and shorten its life. Any tweezers work, but pointed ones give you better control in the small space inside the watch.
Work on a clean, flat surface — a table or desk with good light. Lay out a small cloth or paper towel so you do not lose small parts. If your watch has a gasket or rubber seal inside the case, place it somewhere you can see it so you remember to put it back.
Open the case back by finding the notch and explore steady pressure
Look at the back of your watch. Most Fossil watches have a small notch or slot cut into the edge of the case back. This is where the case opener goes. The notch is usually on one side, sometimes marked with a small line or arrow.
Insert the flat end of the case opener into the notch. Push gently but firmly — do not jab or twist. The case back should pop up slightly. Once you feel it give, work your way around the edge, lifting a little at each point, until the case back comes free. If it does not budge after gentle pressure, stop and take the watch to a jeweler instead. Forcing it risks cracking the case.
Set the case back aside on your cloth. If there is a rubber gasket or seal inside, note which side it sits on so you can replace it the same way.
Remove the old battery and install the new one in the same position
Look inside the watch. The battery is a small, flat, silver coin sitting in a metal holder or clip. Before you touch it, take a photo or make a mental note of which side is facing up — the positive side is usually marked with a + symbol.
Use your tweezers to gently lift the edge of the battery and remove it. If it is stuck, try lifting from a different angle. Once it is out, dispose of it properly — many pharmacies and electronics stores take old batteries for recycling.
Take your new battery and place it in the same position, with the same side facing up. If the old battery had the + side up, the new one should too. Press it down gently until it sits flat in the holder. The watch movement should not move or shift when you do this.
Close the case back and test the watch
Align the case back with the watch body. The notch you used to open it should line up with the case opener slot. Press down firmly and evenly around the edge until you hear or feel a click. The case back should sit flush with the body — no gaps or edges sticking up.
Once the case is closed, press the crown (the button on the side of the watch) or any other buttons to see if the watch responds. If it has a second hand, it should start ticking. If the watch does not start, open the case again and check that the battery is seated properly and facing the right direction.
If the watch still does not work after you have checked the battery twice, the movement may have another problem. Take it to a jeweler or Fossil store for diagnosis.
When to take your watch to a professional instead
If the case back will not open after gentle pressure, or if you feel it cracking, stop when ready. Forcing it will damage the case and make the repair more expensive. A jeweler has specialized tools and can open it without harm.
If your watch is a vintage or limited-edition Fossil, or if it has sentimental value, consider having a professional do the work. The cost is small compared to the risk of damaging something you cannot replace.
If you open the case and the battery holder is corroded, or if the movement looks damaged or wet, do not try to fix it yourself. Take it to a jeweler or Fossil store — corrosion and moisture require professional cleaning and may indicate a deeper problem.
Frequently Asked Questions
How do I know if my Fossil watch battery is dead or if something else is wrong?
A dead battery is the most common reason a Fossil watch stops. If the watch has not run in two to three years, the battery is almost certainly dead. If it stopped suddenly after running normally, or if it runs for a few seconds then stops, the battery may still be the cause. The only way to know for sure is to replace it and see if the watch starts.
Can I use any CR2032 battery, or does it have to be a Fossil brand?
Any CR2032 battery from any brand will work in a Fossil watch that takes a CR2032. The battery type, not the brand, is what matters. Duracell, Energizer, and generic batteries all work the same way. Buy from a reputable source so you know the battery is fresh and not old stock.
What if I lose the gasket when I open the case?
If your watch has a rubber gasket and you lose it, the watch will still work but it will no longer be water-resistant. Water can get inside and damage the movement. If you lose the gasket, take the watch to a jeweler or Fossil store and ask them to install a replacement gasket when they close the case. It costs $5 to $10.
How long does a new battery last in a Fossil watch?
A new battery typically lasts two to three years in a standard Fossil quartz watch. Heavy use, cold temperatures, and older watch movements can shorten battery life. If your watch stops again within a year, the movement may have a problem and you should have it checked by a jeweler.
Is it safe to open my Fossil watch if it is still under warranty?
Opening the case yourself may void the warranty, depending on the terms. Check your warranty paperwork or contact Fossil directly before you open it. If the watch is still under warranty, Fossil or an authorized retailer can replace the battery for free or at a reduced cost.
