What You Need to Do Before Opening Your Watch

Replacing a Michael Kors watch battery yourself is possible if you have the right tools and follow the correct steps, but the process depends on which MK model you own. Most Michael Kors watches use a screw-back case or a snap-back case, and the method for opening each type is different. Before you start, gather a soft cloth, a case opener tool (also called a case back remover), a small flathead screwdriver, tweezers, and a replacement battery in the correct size for your watch model.

The first step is to find out what battery your watch uses. Check the original paperwork that came with your watch, or look at the back of the watch case itself—many models have the battery type printed there. Common sizes for Michael Kors watches include SR626SW, SR927SW, and SR920SW. If you cannot find this information, a jeweler or watch repair shop can tell you the battery type by looking at your watch.

Work on a clean, flat surface with good lighting. Lay out your cloth to prevent small parts from rolling away or getting scratched. Keep your watch pointed away from your face in case the case back pops off suddenly.

Key Takeaways

  • Michael Kors watches use either a screw-back or snap-back case, and you must identify which type yours is before attempting to open it.
  • You will need a case opener tool, a small flathead screwdriver, tweezers, and the correct replacement battery size for your specific watch model.
  • Screw-back cases require you to turn the case back counterclockwise until it comes free, while snap-back cases need gentle prying with a case opener.
  • Once the case is open, note the position of the old battery, remove it with tweezers, and insert the new battery with the positive side facing up.
  • Test your watch before fully closing it, and consider having a jeweler perform the replacement if you are uncomfortable working with small parts.

How to Open a Screw-Back Case

If your Michael Kors watch has a screw-back case, you will see small notches or grooves around the edge of the case back. Position your case opener tool into one of these notches so it grips firmly. Turn the tool counterclockwise slowly and steadily—do not force it, as this can strip the grooves and damage your watch. The case back should turn freely once you have the right grip.

Continue turning until the case back comes completely free. Set it down on your cloth with the inside facing up so you can see the battery and the mechanism inside. Be careful not to lose any small springs or gaskets that may fall out when you open the case.

How to Open a Snap-Back Case

A snap-back case has a smooth edge with no grooves. To open it, insert the thin edge of your case opener tool into the small gap between the case back and the watch body. Gently explore pressure and work your way around the edge, lifting slightly as you go. The case back will pop off once you have released the clips holding it in place.

Work slowly and use even pressure all the way around the edge. If you rush or explore too much force in one spot, you can bend the case back or crack the watch body. Once the case back is loose, lift it away carefully and set it on your cloth.

Removing the Old Battery and Installing the New One

Look inside the watch case and locate the battery. It will be a small, flat, round disc, usually silver in color. Note which side is facing up—this matters for the replacement. Use your tweezers to gently lift the edge of the old battery and remove it. Do not touch the battery with your bare fingers, as oils from your skin can affect its performance.

Before inserting the new battery, check that the inside of the watch case is clean and dry. If you see any dirt or moisture, use a dry cloth to wipe it gently. Now take your new battery with the tweezers and position it so the positive side (marked with a + symbol) faces up, matching the position of the old battery. Press it down gently until it sits flat in the battery compartment.

Some Michael Kors watches have a small metal contact or spring above the battery. Make sure this is in place and not bent before you close the case. If it is bent or missing, the watch will not work even with a new battery.

Testing Your Watch Before Closing It

Before you seal the case back, test whether your watch is working. Hold the watch to your ear and listen for a ticking sound, or look at the second hand to see if it is moving. If the watch does not start, the battery may not be making proper contact. Remove the case back again, use your tweezers to lift the battery slightly, and reseat it firmly.

If the watch still does not work after reseating the battery, try a different new battery of the same type—the first one may have been defective. Do not proceed to close the case until you hear the watch ticking or see the second hand moving.

Closing the Case Back Securely

Once your watch is working, close the case back. For a screw-back case, align the case back with the watch body and turn it clockwise with your case opener tool until it is snug. Do not over-tighten, as this can strip the threads. The case back should be flush with the watch body with no visible gaps.

For a snap-back case, align the case back and press down firmly all the way around the edge until you hear or feel a click. The clips should snap back into place. Check that the case back is sitting evenly and is not tilted or raised on one side.

When to Take Your Watch to a Professional

If your watch has a sealed case with no visible way to open it, or if it is a luxury model with a warranty you want to protect, take it to a jeweler or authorized Michael Kors service center instead. Jewelers have specialized tools and experience that reduce the risk of damaging your watch. The cost is usually between fifteen and forty dollars, depending on your location and the watch model.

If you open your watch and find that the battery compartment contains water or corrosion, or if you see any damaged parts inside, stop and take the watch to a professional. Water damage requires cleaning and drying that you cannot do at home, and attempting to close the case may trap moisture inside and cause further damage.

Frequently Asked Questions

What happens if I put the battery in backwards?

If the negative side of the battery faces up instead of the positive side, your watch will not work. The battery will not make electrical contact with the watch mechanism. straightforward open the case back again, flip the battery over with your tweezers, and reseat it with the positive side up.

Can I use any battery as long as it is the right size?

No. You must use the exact battery type listed for your watch model. Different battery types have different voltages and chemical compositions. Using the wrong type can damage the watch movement or cause the battery to leak. Always match the battery code exactly—for example, SR626SW is not the same as SR927SW.

How often do Michael Kors watch batteries need replacing?

Most watch batteries last between two and four years under normal use. If you wear your watch every day, you may need to replace the battery sooner. If you wear it occasionally, it may last longer. When your watch stops, the battery has run out and needs replacement.

Is it safe to replace the battery myself if I have never done it before?

Yes, if you work slowly and carefully. The main risks are dropping small parts, forcing the case open and damaging it, or putting the battery in backwards. If you are uncomfortable working with tiny objects or your watch is very expensive, paying a jeweler to do it is a reasonable choice.

What should I do with the old battery?

Do not throw watch batteries in the trash. Take them to a battery recycling center, a jewelry store, or an electronics retailer that accepts batteries for recycling. Many places that sell watch batteries also take old ones back for free.
