Remove the watch case back to reach the battery
The first step is opening the back of your Michael Kors watch. Most MK watches use a snap-off case back — a solid metal disc on the rear that pops out rather than screws off. To open it, you need a case back removal tool, which is a flat metal pry tool with a notch designed to fit into the small groove or slot around the edge of the case back.
Place your watch face-down on a soft cloth or towel to protect the crystal. Locate the small slot or groove around the perimeter of the case back. Insert the notch of the case back removal tool into this groove and gently pry upward. The back should pop off with light pressure — do not force it, as too much pressure can damage the case or tool. Once it releases, set the case back aside in a safe place.
If your MK watch has a screw-down case back instead (less common in their standard lines), you will see small screws around the edge. Use a small Phillips or flathead screwdriver to remove these screws, turning counterclockwise. Keep the screws in a small container so you do not lose them.
Key Takeaways
- Michael Kors watches typically use snap-off case backs that require a case back removal tool, not screwdrivers.
- The battery type varies by watch model — check your manual or the old battery itself to find the correct replacement.
- Wear an anti-static wrist strap or touch a grounded metal object before handling the battery to avoid damaging the watch movement.
- If the case back does not pop off easily or the battery is stuck, stop and take the watch to a jeweler rather than risk breaking internal parts.
Identify the correct battery type for your watch
Michael Kors watches use different battery sizes depending on the model. The most common types are SR626SW, SR927SW, SR920SW, and CR2032, but your specific watch may use a different one. The easiest way to find out is to look at the old battery itself once the case back is open — the battery code is printed on the top surface.
If you cannot read the old battery or it has already been removed, check your watch manual or the product documentation that came with the watch. You can also search online for your specific MK watch model number plus "battery" to find the correct type. Do not guess — using the wrong battery size can prevent the watch from keeping time or damage the battery contacts inside.
Once you know the type, purchase a replacement from a pharmacy, electronics store, or online retailer. Batteries cost between $3 and $8 depending on the type. Look for a reputable brand like Energizer, Duracell, or Maxell to may support quality and longevity.
Remove the old battery safely
Before touching the battery or any internal parts, ground yourself to avoid static electricity damage. Wear an anti-static wrist strap if you have one, or straightforward touch a grounded metal object like a sink or radiator with your bare hand. This discharges any static charge you may be carrying.
Look inside the open case back. You will see the battery sitting in a small metal holder or battery contact. The battery may be held in place by a small metal clip or spring. If there is a clip, gently lift it away from the battery. If the battery is straightforward resting in the holder, you can carefully lift it out with your fingernail or a plastic tool — never use a metal tool directly on the battery, as this can cause a short circuit.
Once the old battery is out, set it aside. Do not throw it in the trash — batteries contain chemicals and should be recycled. Most pharmacies and electronics stores have battery recycling bins near the checkout.
Insert the new battery and close the case
Take your new battery and check the orientation. Batteries have a positive side (marked with a + symbol) and a negative side (marked with a − symbol). The positive side should face upward, toward the watch face. Slide or place the new battery into the metal holder, making sure it sits flat and level.
If there was a metal clip holding the old battery, gently lower the clip back over the new battery to find it. The clip should hold the battery firmly without being so tight that it bends or damages the battery casing. Test the watch by holding it to your ear — you should hear a faint ticking sound if the battery is making contact and the watch is running.
Once you confirm the watch is working, carefully align the case back with the opening. The snap-off back should have a small notch or alignment mark that lines up with a corresponding mark on the watch case. Press down firmly and evenly around the edge until you hear or feel a click — the back should snap into place with a satisfying pop. If you removed screws, reinstall them by turning clockwise until snug, but do not over-tighten.
Test the watch and troubleshoot common problems
After closing the case back, wear the watch for a few minutes and check that it is keeping time. If the second hand is moving smoothly, the battery is installed correctly. If the watch does not start or the hand moves in stuttering motions, the battery may not be making proper contact.
If the watch does not work, open the case back again and check that the battery is seated flat in its holder and that the positive side is facing up. Also inspect the metal battery contacts inside the case to see if they are dirty or corroded. If they look tarnished, gently clean them with a dry cotton swab. Reinstall the battery and test again.
If the watch still does not work after you have checked the battery twice, the problem may be with the watch movement itself rather than the battery. At that point, take the watch to a jeweler or authorized Michael Kors service center — they have the tools and informed to diagnose internal issues.
When to take your watch to a professional
Some situations call for professional help rather than a DIY battery change. If the case back is stuck or will not pop off even with gentle prying, forcing it can crack the case or strip the threads. If the battery is corroded or stuck in its holder, trying to remove it yourself can damage the delicate contacts inside. If water leaks out when you open the case back, the watch may have a damaged seal and needs professional service before you install a new battery.
A jeweler or watch repair shop can handle these issues safely and will often replace the battery for $10 to $25 in labor, plus the cost of the battery itself. This is worth the cost if you are unsure about opening the watch or if something seems wrong during the process.
Frequently Asked Questions
How long does a Michael Kors watch battery last?
Most MK watch batteries last between two and three years with normal daily wear. Battery life depends on the watch model, how often you wear it, and whether it has features like a date window or chronograph that draw more power. If your watch stops working sooner, the battery may be defective or the watch may have an internal problem.
Can I change the battery myself or should I go to a jeweler?
You can change the battery yourself if you have a case back removal tool and feel comfortable working with small parts. If you do not have the tool, are unsure about the process, or the case back seems stuck, a jeweler is the safer choice. The cost is modest and you avoid the risk of damaging the watch.
What if I lose a screw from the case back?
If your MK watch has a screw-down case back and you lose a screw, a jeweler can usually replace it with a matching one. Bring the watch and the remaining screws so they can match the size and thread type. Do not use a random screw from your junk drawer, as it may not fit properly and could damage the case.
Is it normal for water to come out when I open the case back?
No. If water leaks out, the watch has a damaged water-resistance seal and should not be worn until it is serviced. Take it to a jeweler or authorized service center — they can replace the seal and may support the watch is waterproof again before you install a new battery.
How do I know if the battery is installed correctly?
The watch should start ticking within a few seconds of closing the case back. Hold it to your ear and listen for a steady ticking sound. If you hear nothing or the second hand moves in jerky motions, open the case back and check that the battery is seated flat and the positive side faces up.
