If you’ve noticed your Michael Kors watch slowing down or stopping altogether, it might be time for a fresh battery. Knowing how to change an MK watch battery not only saves you time and money but also gives you the satisfaction of maintaining your stylish timepiece yourself. Whether your watch is a daily accessory or a special occasion piece, keeping it powered ensures it continues to complement your look flawlessly.

Replacing the battery in a Michael Kors watch may seem daunting at first, especially if you’re unfamiliar with watch components or delicate mechanisms. However, with a bit of guidance and the right tools, the process can be straightforward and manageable. Understanding the basics of your watch’s design and battery type is key to ensuring a successful replacement without compromising its functionality or aesthetic.

This article will walk you through the essentials of changing your MK watch battery, highlighting important considerations and common pitfalls to avoid. By the end, you’ll feel confident in your ability to give your watch a new lease on life, all from the comfort of your own home.

Accessing the Back Cover of Your MK Watch

To replace the battery in your Michael Kors (MK) watch, the first step is to carefully access the back cover. The method for opening the back depends on the specific model of your watch, as MK watches often use either a snap-off case back or a screw-down case back.

For watches with a snap-off back, use a thin, flat tool such as a case knife or a small flathead screwdriver. Insert the tool gently into the small notch on the edge of the back cover and apply slight pressure to pry it open. Avoid using excessive force to prevent damaging the case or scratching the watch.

If your MK watch has a screw-down case back, it will have multiple notches or grooves around the perimeter. Use a case back wrench or a specialized watch opener tool designed to fit these grooves. Align the tool carefully and turn counterclockwise to unscrew the back cover.

In either case, ensure you work on a clean, flat surface and consider placing a soft cloth underneath the watch to avoid scratches. Wearing gloves or using plastic tools can also help prevent oils from your skin from contaminating the watch components.

Identifying and Removing the Old Battery

Once the back cover is removed, you will see the watch movement and the battery compartment. The battery is typically held in place by a small metal clip or retaining arm. Take note of the battery’s orientation (positive and negative sides) before removal, as this will be crucial when installing the new battery.

To remove the battery:

  • Use a pair of plastic tweezers or a non-metallic tool to avoid short-circuiting the battery or damaging the movement.
  • Gently lift or slide the retaining clip aside.
  • Carefully extract the battery from its compartment.

Do not touch the battery or internal components with your bare hands, as oils and static electricity can cause damage or corrosion.

Selecting the Correct Replacement Battery

MK watches commonly use silver oxide button cell batteries, but the exact model varies depending on the watch. The battery type and number are usually printed on the old battery itself. Common types include SR626SW, SR621SW, or SR920SW.

If the battery code is not visible, consult the watch manual or the official MK website for your watch model specifications. Using the correct battery type ensures proper voltage and longevity.

Battery Code Diameter (mm) Height (mm) Voltage (V) Common MK Models
SR626SW 6.8 2.6 1.55 Runway, Parker
SR621SW 6.8 2.1 1.55 Bradshaw, Lexington
SR920SW 9.5 2.1 1.55 Layton, Sofie

When purchasing replacement batteries, opt for high-quality brands to avoid leakage or premature failure.

Installing the New Battery and Reassembling the Watch

With the new battery in hand, install it in the same orientation as the old one, ensuring the positive (+) side aligns with the marking in the battery compartment. Use plastic tweezers to place the battery carefully under the retaining clip.

Before closing the back cover, verify that the watch is functioning by observing the second hand or digital display. If the watch does not start, double-check the battery placement and ensure proper contact with the terminals.

To reassemble:

  • For snap-off backs, align the back cover with the case and press firmly until it snaps into place. Use a case press tool if available to avoid uneven pressure or damage.
  • For screw-down backs, place the cover and turn clockwise using the case back wrench until snug. Do not overtighten, as this may strip the threads.

After resealing the back, set the correct time and date on your MK watch, and check for proper operation over the next 24 hours to ensure the battery replacement was successful.

Identifying the Correct Battery Type for Your MK Watch

Before attempting to replace the battery in your Michael Kors (MK) watch, it is crucial to determine the exact battery model required. Using the wrong battery can damage the watch or cause it to malfunction.

The battery type is usually indicated on the watch back or in the user manual. If neither is available, consult official MK resources or authorized service centers. Common battery types for MK watches include silver oxide button cells, such as SR626SW or SR920SW, but this varies by model.

MK Watch Model Common Battery Type Battery Voltage Notes
Runway Series SR920SW (371) 1.55V Standard silver oxide button cell
Bradshaw Series SR626SW (377) 1.55V Common for smaller watches
Lexington Series SR920SW (371) 1.55V Often used in chronograph models
Other MK Models Varies 1.55V typical Check model-specific details

It is recommended to use high-quality batteries from reputable manufacturers to ensure optimal performance and longevity.

Tools and Precautions Needed for Battery Replacement

Replacing the battery in an MK watch requires precision and care to avoid damaging delicate components. The following tools and precautions are essential:

  • Watch Case Opener: A dedicated case knife or case wrench suited to the watch back type (snap-off or screw-down).
  • Tweezers: Non-magnetic, preferably plastic or anti-static, to handle the battery without causing short circuits.
  • Small Screwdrivers: Precision flathead or Phillips screwdrivers for removing movement clamps or battery holders.
  • Soft Cloth or Mat: To work on and prevent scratches on the watch or components.
  • Gloves or Finger Cots: To avoid contaminating the battery or internal parts with oils or dirt.
  • Magnifying Glass or Loupe: For detailed work, especially with small screws and components.

Precautions:

  • Work in a clean, well-lit environment to avoid losing tiny parts.
  • Discharge static electricity by touching a grounded metal object before handling the movement.
  • Be gentle when opening the case back to prevent deformation or damage to the gasket.
  • Note the orientation of the battery before removal to ensure correct placement of the new one.
  • Inspect and, if necessary, replace the gasket to maintain water resistance.
