You can change an MK watch battery yourself with basic tools, or pay a jeweler to do it

Michael Kors watches use standard coin-cell batteries — usually CR2032, CR2025, or SR626SW depending on the model. You can buy the correct battery at a drugstore, supermarket, or online for $3 to $8. The job takes 15 to 30 minutes if you do it yourself and requires only a small flathead screwdriver, a plastic pry tool (or a butter knife), and a clean, flat work surface.

If you are uncomfortable opening the watch or want to avoid the risk of damaging the case, a jeweler or watch repair shop will change it for $15 to $40, usually while you wait. This is the safer choice if your watch is water-resistant or if the case back is stuck.

Key Takeaways

  • MK watches typically use CR2032, CR2025, or SR626SW batteries, which you can find at any drugstore or online for a few dollars.
  • The back of the watch case either screws off or pries off with a flat tool — check your watch model to know which method applies.
  • Once the case is open, note the battery position and orientation before removing it, then drop in the new battery the same way.
  • A jeweler or watch repair shop can do the job for $15 to $40 if you prefer not to open the watch yourself.

Find out what battery your MK watch uses

The battery type is printed on the back of the watch case or inside the case once you open it. Look for a code like CR2032, CR2025, CR2016, or SR626SW. If you cannot see it, check the Michael Kors website or your watch manual — enter your model number and it will tell you the battery type.

Once you know the type, buy a replacement battery. Pharmacies like CVS and Walgreens stock common types like CR2032 in the watch or battery section. Amazon, eBay, and battery-specific sites like Batteries Plus carry all types. A single battery costs $3 to $8. Buy one or two extras so you have a spare when the next battery dies.

Determine whether your watch case screws or pries open

The back of an MK watch either has a screw-down case back or a snap-on case back. Look at the back of the watch. If you see a thin groove or seam running around the edge and small notches or indentations, it is a screw-down case. If the back looks smooth with just a seam, it is a snap-on case that pries off.

Screw-down cases are more common on MK watches. You will need a small flathead screwdriver that fits the notches without slipping — a jeweler's screwdriver set works best, but a precision screwdriver from a hardware store will do. For snap-on cases, you need a plastic pry tool, a butter knife, or a coin to gently lever the back off without scratching the case.

Open a screw-down case back

Place the watch face-down on a clean, soft cloth or towel so the crystal does not get scratched. Position the screwdriver in one of the notches on the case back and turn counterclockwise slowly. Do not force it — if the screwdriver does not fit snugly, try a different size. Once the back is loose, unscrew it by hand the rest of the way and set it aside on a clean surface.

Inside, you will see the battery held in a small metal clip or sitting in a shallow cup. Note which side is facing up — the positive side (marked with a + or a flat surface) should face up on most MK watches. Take a photo with your phone if you are unsure. Gently lift the battery out with your fingernail or a plastic tool and set it aside.

Open a snap-on case back

Place the watch face-down on a soft cloth. Locate the seam where the case back meets the case body — it runs around the edge. Insert a plastic pry tool, butter knife, or coin into the seam at the point farthest from any crown or button. Gently lever the back upward with steady, even pressure. Do not pry hard or you risk cracking the case or scratching the back.

Once you feel the back start to lift, work your way around the seam, prying gently at two or three points until the back comes free. Inside, the battery will be held in place by a clip or cup. Note the orientation — which side faces up — before you remove it. Lift the old battery out carefully and set it aside.

Install the new battery and close the case

Drop the new battery into the same position as the old one, with the positive side facing the same direction. Press it down gently until it sits flat and the clip or cup holds it in place. Do not force it — it should sit snugly without pressure.

For a screw-down case, align the back with the case body and screw it clockwise by hand until it is snug. Do not over-tighten — once it is hand-tight, stop. For a snap-on case, align the back with the case body and press down firmly around the edges until you hear or feel a click. Work your way around the seam to make sure it seats evenly all the way around. Once the case is closed, press the crown (the knob on the side) to make sure the watch still works and the time is correct. If the watch does not respond, open the case again and check that the battery is seated properly and facing the right direction.

When to take your watch to a jeweler instead

If your watch is water-resistant or has a sealed case, opening it yourself can damage the seal and let water in. Check your watch manual or the Michael Kors website to see if your model is water-resistant. If it is, take it to a jeweler or an authorized Michael Kors retailer — they have the tools to reseal the case properly.

If the case back is stuck or the screws are stripped, do not force it. A jeweler has the right tools and experience to open it without damage. The same applies if you are uncomfortable with the process or worried about scratching the watch. The cost of a professional battery change ($15 to $40) is usually less than the cost of repairing a damaged case or crystal.

Frequently Asked Questions

How long does an MK watch battery last?

Most MK watch batteries last two to three years with normal daily wear. Heavy use, exposure to cold, or a watch that runs fast can shorten battery life. When the watch stops or runs slow, the battery is dead and needs replacement.

Can I use any CR2032 battery, or does it have to be a specific brand?

Any CR2032 battery will work as long as it is the correct type for your watch. Duracell, Energizer, Maxell, and generic store brands all perform the same way. Buy from a reputable source to avoid counterfeit batteries, but the brand name does not matter.

What if I drop the battery inside the watch case?

If the battery falls into the case, tilt the watch gently to roll it back into view. Do not shake it hard. Once you can see it, use a plastic tool or your fingernail to guide it back into the battery cup. If you cannot retrieve it, take the watch to a jeweler — they can open it fully and get the battery out.

Is it safe to wear the watch right after I change the battery?

Yes, as long as the case is closed properly and the watch is not water-resistant. If your watch is water-resistant, wait a few hours to make sure no moisture got inside during the battery change. If you see condensation under the crystal, take it to a jeweler to have the case resealed.

What should I do with the old battery?

Take the old battery to a pharmacy, electronics store, or hazardous waste collection site. Many drugstores have battery recycling bins near the checkout. Do not throw it in the trash — batteries contain materials that should be recycled.
