You can change a Michael Kors watch battery yourself with basic tools, or take it to a jeweler or Michael Kors store
A Michael Kors watch battery typically lasts two to three years before it stops working. When your watch stops, you have three options: open the case back yourself with a case opener tool, visit a Michael Kors retail store, or take it to a jeweler. The DIY route costs $5 to $15 for a replacement battery and a case opener tool. A jeweler usually charges $15 to $30 for the service. Michael Kors stores charge $25 to $50, depending on the watch model.
The watch model matters. Some Michael Kors watches have screw-down case backs that require a special tool. Others have snap-on backs you can pry open with a flat tool. Before you start, check your watch documentation or search for your specific model number online to see which type you have.
Key Takeaways
- Michael Kors watches use standard coin-cell batteries, usually CR2032 or similar sizes, which cost $3 to $8 at drugstores or online.
- A case opener tool (also called a case back remover) costs $5 to $15 and works on most snap-on case backs, but screw-down backs need a different tool.
- The DIY process takes 10 to 15 minutes and involves opening the case, removing the old battery, inserting the new one, and closing the case back.
- If your watch is water-resistant, opening it yourself may void that protection; a jeweler can reseal it properly for $10 to $20 extra.
- Michael Kors stores and jewelers handle the work if you prefer not to open the watch yourself, though it costs more and takes longer.
Finding the right battery size for your watch
Michael Kors watches use standard coin-cell batteries that you can buy at any drugstore, supermarket, or online retailer. The most common sizes are CR2032, CR2025, and SR626SW. Your watch manual or the inside of the case back usually prints the battery type. If you cannot find that information, search online for your watch model number plus "battery type" — Michael Kors forums and watch sites have this information for most models.
A CR2032 battery costs $3 to $8 depending on the brand and where you buy it. Energizer, Duracell, and store brands all work the same way. Buy one extra in case you drop it or install it incorrectly the first time. Some jewelers sell batteries too, but their prices are usually higher than a drugstore.
Tools you need to open the case back
A case opener tool (also called a case back remover or watch case opener) is the main tool you need. These cost $5 to $15 on Amazon or at jewelry supply stores. The tool has a handle with three or four metal prongs that fit into the notches on the case back. You insert the prongs, turn the handle counterclockwise, and the case back unscrews or pops off.
If your watch has a screw-down case back (common on water-resistant models), you may need a case wrench instead, which costs $8 to $20. A case wrench has a different design with adjustable pins that grip the case back. Check your watch model first — most Michael Kors watches use the standard case opener tool, not a wrench.
You will also need a clean, flat surface to work on and a small container to hold the tiny screws if your watch has any. A soft cloth or watch mat prevents scratches on the case.
Step-by-step process for opening the case and replacing the battery
Place your watch face-down on a soft cloth or mat. Locate the notches on the case back — these are small indentations around the edge where the case opener tool prongs fit. Insert the three or four prongs into the notches, making sure they sit firmly in the grooves.
Turn the handle of the case opener counterclockwise slowly and steadily. You should feel resistance, but do not force it — if it is stuck, check that all prongs are seated correctly. After a quarter turn or so, the case back will either pop off (snap-on style) or unscrew completely (threaded style). Set the case back aside on your cloth.
Inside, you will see the battery held in place by a metal clip or sitting loose in a small compartment. If there is a clip, gently lift one end to release the old battery. If the battery is loose, carefully pick it up with your fingernail or a plastic tool — avoid touching the battery surface with your bare fingers, as oils can affect performance. Drop the old battery into your container.
Insert the new battery with the positive side (marked with a + or the shiny side) facing up. If there is a clip, slide it back over the battery to hold it in place. Close the case back by reversing the opening process: align the notches, insert the case opener prongs, and turn clockwise until snug. Do not over-tighten — you will hear or feel a click when it is seated correctly.
When to take your watch to a professional instead
If your watch is water-resistant or water-proof, opening it yourself breaks the seal. Water can seep into the movement and damage the internal parts. A jeweler can open the watch, replace the battery, and reseal it with a new gasket for $10 to $20 extra. This is worth the cost if your watch is water-resistant.
If you cannot find the battery type, are unsure which tool to use, or the case back will not budge after gentle turning, take it to a jeweler or Michael Kors store. Forcing a stuck case back can crack the back or strip the notches, making future battery changes impossible. A professional can open it safely.
Michael Kors stores offer battery replacement at most locations, though you may need to visit during business hours and wait a few days. Call ahead to confirm they offer the service and ask about the cost for your specific model. Some stores do it while you wait; others send it to a repair center.
What to do if the watch still does not work after the battery change
After you install the new battery, the watch should start when ready. If it does not, the battery may be installed backwards — positive side should face up. Open the case back again and flip the battery. If it still does not work, try a different new battery from a different package, in case the first one was defective.
If the watch still does not run, the problem is likely not the battery. The movement (the internal mechanism) may be damaged, or the battery contacts may be corroded. This is beyond a straightforward battery change and requires professional repair. Take it to a jeweler or Michael Kors store for diagnosis.
Cost comparison: DIY versus professional service
| Option | Cost | Time | Best for |
|---|---|---|---|
| DIY with case opener tool | $8 to $23 (tool + battery) | 10 to 15 minutes | Non-water-resistant watches, multiple battery changes |
| Jeweler | $15 to $50 | Same day to one week | Water-resistant watches, stuck case backs, peace of mind |
| Michael Kors store | $25 to $50 | Same day to one week | Warranty concerns, brand-specific service |
If you own multiple Michael Kors watches, buying a case opener tool once makes DIY the cheapest long-term option. If you have only one watch and it is water-resistant, a jeweler is the safer choice because they can reseal it properly.
Frequently Asked Questions
Can I use any coin-cell battery, or does it have to be a Michael Kors brand?
Any standard coin-cell battery of the correct size works. Michael Kors does not make batteries — they use the same CR2032 or similar batteries that any watch brand uses. Energizer, Duracell, Panasonic, and store brands are all compatible. Buy from a reputable source to avoid counterfeit batteries.
What if I drop the battery inside the watch case?
If the battery falls into the case, use a small magnet or a piece of tape (sticky side out) on the end of a thin stick to retrieve it. Do not shake the watch or tilt it too much, as you may damage other internal parts. If you cannot retrieve it safely, take the watch to a jeweler.
Will opening the watch myself void the warranty?
Opening the case back yourself may void any remaining warranty, especially if the watch is water-resistant. Check your warranty documentation or contact Michael Kors customer service before opening it. If the watch is still under warranty, have a professional handle the battery change to keep the warranty intact.
How do I know if my Michael Kors watch is water-resistant?
Check the case back or the original documentation for a marking like "3 ATM", "5 ATM", "10 ATM", or "water-resistant". Any marking that includes "water" or "ATM" means the watch has a water-resistant seal. If you see no marking, assume it is not water-resistant, but opening it still risks dust or moisture entering. A jeweler is the safer choice.
Can I replace the battery in a Michael Kors smartwatch the same way?
No. Michael Kors smartwatches have rechargeable batteries that you charge with a cable or dock, not replaceable coin-cell batteries. If a smartwatch battery stops holding a charge, it requires professional service or replacement. Contact Michael Kors customer service or visit a store for repair options.
