You can change 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 powering the watch. When your watch stops, the battery is usually the culprit. You have two paths: open the case back yourself using a case opener tool and a fresh battery, or pay a jeweler or watch repair shop to do it. The DIY route costs $10 to $20 for tools and a battery. A jeweler or repair shop typically charges $15 to $50 for the same work, depending on your location and whether they need to order a specific battery type.

Before you start, identify your watch model and find the correct battery type. Michael Kors watches use common battery sizes like SR626SW, SR927SW, or CR2032—you can find this information in your watch manual or by searching your model number online. Once you know the battery type, you can decide whether to tackle it yourself or hand it off to a professional.

Key Takeaways

  • Michael Kors watch batteries last two to three years and cost $10 to $20 to replace yourself or $15 to $50 at a jeweler.
  • You need a case opener tool (also called a case back opener), a small screwdriver, and the correct replacement battery for your specific model.
  • The case back is usually held on by a screw or snap fit—check your manual to know which type your watch uses.
  • If you are uncomfortable opening the watch or it has a sealed case back, a jeweler can do the work safely without risking damage to the watch.

Find your watch model and battery type

Look at the back of your watch case for the model number, usually printed or engraved there. Write it down. Then search online for "[your model number] battery type" or check your original watch documentation if you still have it. Michael Kors publishes battery information for most models on their website and in product manuals.

Once you have the battery type, you can order it from a pharmacy, electronics store, or online retailer. Common Michael Kors battery types include SR626SW (silver oxide), SR927SW, and CR2032 (coin cell). Buy one battery and keep the packaging—you may need to return to the store if you order the wrong type.

Gather the tools you need

You will need three things: a case opener tool, a small flathead screwdriver, and your replacement battery. A case opener tool (also called a case back opener or watch opener) is a small metal device with a notch or prongs that grip the case back. You can buy one for $5 to $15 at a pharmacy, jewelry supply store, or online. Do not try to pry the case open with a regular screwdriver or knife—you will scratch or dent the watch.

The small screwdriver is for removing the battery holder or clip inside the case, if your watch uses one. A jeweler's screwdriver set costs $10 to $20 and includes multiple sizes. If you only plan to change one battery, you may borrow a screwdriver from a friend or use one you already own, as long as the blade fits the screw without forcing it.

Open the case back safely

Place the watch face-down on a soft surface like a towel or cloth to protect the crystal. Look at the case back to see how it is sealed. Most Michael Kors watches use one of two methods: a screw-on case back (held by one or more small screws) or a snap-fit case back (pressed on without screws).

If your case back has visible screws, use the small screwdriver to remove them one at a time, placing each screw in a small cup or dish so you do not lose it. If the case back is snap-fit with no screws, position the case opener tool in the notch or groove at the edge of the case back and gently turn or pry it counterclockwise. Work slowly and explore even pressure—forcing it can crack the case or bend the opener tool.

Once the case back is loose, lift it away carefully. You will see the battery, usually held in place by a small metal clip or sitting loose in a plastic holder. Do not touch the crystal or any other internal parts while the case is open.

Remove the old battery and install the new one

If the battery is held by a metal clip, gently lift one end of the clip to free the battery, then slide the battery out. If it is sitting loose, straightforward pick it up. Set the old battery aside—you can dispose of it at a pharmacy or electronics recycling center, as watch batteries contain small amounts of mercury or other metals.

Before you insert the new battery, check the orientation. Most watch batteries have a flat side (negative) and a raised side (positive). The positive side should face up toward the top of the watch. Slide the new battery into place, then find it under the metal clip if your watch uses one. Make sure the battery sits flat and does not tilt.

Close the case back and test the watch

If your case back screws on, align it with the case and insert the screws by hand first to avoid cross-threading. Then tighten each screw gently with the screwdriver—do not over-tighten, as this can strip the threads. If the case back is snap-fit, align it with the case and press down firmly around the edges until you hear or feel a click. You may need to use the case opener tool to help seat it fully.

Once the case back is sealed, flip the watch over and check that it is running. You should see the second hand moving. If the watch does not start, the battery may be inserted backward or the old battery may have been defective. Open the case back again, flip the battery, and test once more. If it still does not work after two attempts, take the watch to a jeweler—there may be an internal issue beyond the battery.

When to take your watch to a professional

If your watch has a sealed case back with no visible screws or notches, do not force it open. Some Michael Kors watches are designed to be opened only by a jeweler or authorized service center. Forcing a sealed case can crack the crystal, damage the gasket that keeps the watch water-resistant, or bend the case itself.

You should also take your watch to a professional if you are uncomfortable working with small parts, if you lose a screw during the process, or if the watch still does not run after you install a fresh battery. A jeweler can also test the battery and movement to rule out other problems. Many jewelry stores and watch repair shops offer this service while you wait, usually for $15 to $50 depending on your location.

Frequently Asked Questions

How do I know if my Michael Kors watch battery is dead?

The second hand will stop moving, or the watch will run slowly and then stop. Some watches also have a battery indicator—the second hand may tick every few seconds instead of continuously, which signals low battery. If the watch has not run in weeks, the battery is almost certainly dead.

Can I use any battery in my Michael Kors watch?

No. You must use the exact battery type specified for your model. Using the wrong size or chemistry can damage the watch movement or cause the battery to leak. Always check your manual or search your model number before buying a replacement.

What if I drop a screw while opening the case back?

Stop and look for it when ready on the surface where you are working. If you cannot find it, take the watch to a jeweler with the case back open. They can install a replacement screw that matches the original. Do not close the case back without all screws in place, as it may not seal properly.

Will changing the battery myself void my warranty?

Michael Kors warranties typically do not cover battery replacement, so changing it yourself will not void coverage for other defects. However, if you damage the watch while opening it, that damage may not be covered. If your watch is still under warranty and you are unsure, contact Michael Kors customer service before opening it.

How long does a new battery last in a Michael Kors watch?

Most watch batteries last two to three years with normal daily wear. Battery life depends on how often you wear the watch and whether it has features like a chronograph or constant second hand, which drain the battery faster. A watch worn occasionally may keep a battery for four years or more.
