You can replace a Michael Kors watch battery yourself with basic tools, or take it to a jeweler or watch repair shop

A Michael Kors watch battery typically lasts two to three years before it stops holding a charge. When your watch stops, you have two paths: open the case back yourself using a case opener tool and swap in a fresh battery, or pay a jeweler or department store watch counter to do it for you. The DIY route costs $5 to $15 for the battery and tool; a professional replacement usually runs $15 to $40 depending on where you go.

The method depends on your watch model. Most Michael Kors watches use a screw-down case back (you turn it counterclockwise to open) or a snap-on case back (you pry it off with a flat tool). A few models are sealed and cannot be opened at home. Before you start, check your watch manual or the Michael Kors website to confirm your model can be serviced at home.

Key Takeaways

  • Michael Kors watches with screw-down or snap-on case backs can be opened at home with a case opener tool and a fresh battery.
  • You need to know your exact battery model number, which is printed on the old battery or listed in your watch manual.
  • Screw-down case backs turn counterclockwise; snap-on backs require a flat prying tool and gentle pressure to avoid scratching the case.
  • If your watch is water-resistant, have a professional replace the battery to may support the seal stays intact.
  • A jeweler or department store watch counter can replace the battery for you if you prefer not to open the case yourself.

Find your battery model number before you buy a replacement

The battery inside your Michael Kors watch has a specific model number printed on it. You need this number to buy the correct replacement, because watches use different battery sizes and voltages. If your watch still runs, you can sometimes find the model number in your user manual under "specifications" or "battery information." If the watch is dead, you will need to open the case back first to read the number off the old battery itself.

Common Michael Kors watch batteries include SR626SW, SR927SW, SR920SW, and CR2032, but your model may use a different one. Once you have the number, search for it online or ask a jeweler. Battery prices range from $3 to $8 depending on the type. Buy from a pharmacy, electronics store, jeweler, or online retailer — avoid extremely cheap batteries, as they may not last as long or hold voltage as reliably.

Gather the tools you need for a screw-down case back

A screw-down case back is sealed by turning it clockwise (like a jar lid). To open it, you turn counterclockwise. You will need a case opener tool — a small metal device with notches or pins that grip the grooves on the case back. These cost $5 to $15 and are sold at jewelry supply stores, online retailers, and some pharmacies. You may also see them called a "watch case opener" or "case back remover."

You will also need a small flathead screwdriver (to remove the battery holder or clip inside), tweezers (to lift the old battery out without dropping it), and a clean, flat work surface. Lay down a white cloth or paper towel so you can see small parts if they fall. Wear an anti-static wrist strap if you have one, though it is not required for battery replacement.

Open a screw-down case back and remove the old battery

Place your watch face-down on the cloth. Fit the case opener tool into the grooves on the case back — the notches should grip firmly. Turn the tool counterclockwise slowly and steadily. Do not force it; if it does not turn, reposition the tool so the notches sit deeper in the grooves. After a quarter turn or so, the case back will loosen. Unscrew it the rest of the way by hand.

Inside, you will see the battery held in place by a small metal clip or plastic holder. Use the flathead screwdriver to gently lift one end of the clip away from the battery. Once the clip is loose, use tweezers to lift the old battery straight up and out. Do not touch the flat surfaces of the new battery with your bare fingers — skin oils can reduce its lifespan. If the battery holder is dirty, wipe it gently with a dry cloth.

Slide the new battery into the holder with the positive side (marked with a + symbol) facing up. Press the metal clip back down over the battery until it clicks or sits flush. Check that the battery does not move when you gently shake the watch. Screw the case back on by turning it clockwise with the case opener tool until it is snug — do not over-tighten, as you can strip the threads.

Open a snap-on case back and replace the battery

A snap-on case back has no grooves or threads. Instead, it is held in place by a tight seal that you pry open. Place your watch face-down on the cloth. Locate the small gap between the case back and the watch body — it is usually on one edge. Slide a flat tool (a butter knife, flathead screwdriver, or plastic pry tool) into the gap and explore gentle, steady pressure to lift the case back up. Work your way around the edge if needed, lifting a little at a time rather than forcing one spot.

Once the case back pops off, you will see the battery and its holder. Follow the same steps as above: use a screwdriver to lift the battery clip, remove the old battery with tweezers, and insert the new battery positive-side up. Press the clip back down. Before you snap the case back on, check that the rubber gasket (a thin ring around the inside edge) is clean and in place — this seal keeps moisture out. Snap the case back on by pressing down firmly and evenly around the edges until you hear or feel it click into place.

Test your watch and know when to see a professional

After you close the case back, set your watch to the correct time and wear it for a few hours. The second hand should move smoothly and continuously. If the watch does not start, the battery may not be making good contact with the holder. Open the case back again, remove the battery, and check that the clip is positioned correctly and the battery is sitting flat in the holder.

If your watch is water-resistant (rated for water resistance at any depth), do not replace the battery yourself. The rubber gasket that seals the case back can wear out or be damaged during opening, and a professional jeweler has the tools to test the seal after replacement. Similarly, if your watch has a sealed case back with no visible grooves or seams, it cannot be opened at home — take it to a jeweler. If you are unsure whether your model can be serviced at home, contact Michael Kors customer service or a local watch repair shop before you attempt to open it.

Where to go if you prefer professional replacement

A jewelry store, watch repair shop, or department store watch counter can replace your battery in 15 to 30 minutes while you wait. Costs range from $15 to $40 depending on the location and battery type. Department stores like Macy's or Kohl's often offer watch battery replacement at their jewelry counters. Independent jewelers and watch repair shops are usually less expensive and may offer a warranty on the work.

Before you go, call ahead to confirm they service Michael Kors watches and ask about their turnaround time and price. Bring your watch and, if you have it, your user manual. A professional will also inspect the watch for any other issues, such as a cracked crystal or loose band, and can advise you on repairs. If your watch is still under warranty, check the Michael Kors website or contact customer service to see if battery replacement is covered.

Frequently Asked Questions

How long does a Michael Kors watch battery last?

Most Michael Kors watch batteries last two to three years with normal daily wear. Battery life depends on the watch model, how often you use features like the stopwatch or backlight, and the battery type. If your watch stops suddenly after only a few months, the battery may be defective — take it to a jeweler to confirm.

Can I use any battery in my Michael Kors watch?

No. You must use the exact battery model number specified for your watch. Using the wrong battery can damage the watch or cause it to stop working. Always check your manual or the old battery before you buy a replacement.

What if I drop the battery inside the watch?

If a small battery falls into the watch case, do not shake or tilt the watch — you may damage internal parts. Place the watch on a flat surface and use a flashlight to locate the battery. If you cannot reach it safely with tweezers, take the watch to a jeweler rather than risk breaking something inside.

Do I need to reset my Michael Kors watch after replacing the battery?

No. Once the new battery is in place and the case is closed, your watch should resume normal operation. You will need to set the correct time and date, just as you would after the battery dies. Some digital Michael Kors watches may require you to press a reset button — check your manual for details.

Will opening the case back void my warranty?

Opening the case back yourself may void your warranty, depending on the terms. Check your warranty paperwork or contact Michael Kors customer service before you open the watch. If your watch is still under warranty, it is safer to have a professional replace the battery.
