AvatarByArron Moss Watch Maintenance

If you own a sleek MVMT watch, you know it’s more than just a timepiece—it’s a statement of style and precision. But like all battery-powered watches, even your favorite MVMT model will eventually need a fresh battery to keep ticking smoothly. Knowing how to replace your MVMT watch battery can save you time, money, and the hassle of visiting a jeweler or watch repair shop.

Replacing the battery in your MVMT watch might seem daunting at first, especially if you’re unfamiliar with the delicate components inside. However, with the right approach and a bit of care, it’s a manageable task that many watch owners can confidently tackle themselves. Understanding the basics of your watch’s design and the tools required will empower you to extend its life and maintain its flawless functionality.

In the following sections, we’ll explore what you need to know before starting, the general process involved, and some helpful tips to ensure a smooth battery replacement. Whether you’re a seasoned DIYer or a first-timer, this guide will prepare you to bring your MVMT watch back to life with ease.

Opening the Watch Case

To begin replacing the battery in your MVMT watch, it is essential to carefully open the case back without causing any damage. MVMT watches typically feature a snap-on or screw-down case back, depending on the model.

For snap-on case backs, use a thin, flat tool such as a case knife or a small flathead screwdriver. Insert the tool into the small notch or gap along the edge of the case back and gently pry it open. Take care not to scratch or deform the metal.

For screw-down case backs, you will need a case back wrench or a specialized tool designed to engage the notches on the back. Align the tool properly and turn counterclockwise to unscrew the back. Avoid applying excessive force to prevent stripping the threads.

Ensure you work on a clean, flat surface with good lighting to prevent losing any small components or screws. It is advisable to wear anti-static gloves or finger cots to avoid contaminating internal parts with oils or dirt.

Removing the Old Battery

Once the case back is removed, identify the battery compartment. MVMT watches usually have a small clip or retainer holding the battery in place. Carefully observe how the battery is positioned before removal to ensure correct placement of the new battery.

Use non-metallic tweezers or a plastic tool to gently lift the clip or retainer without applying excessive force. Then, remove the battery by sliding it out or lifting it gently.

Avoid touching the battery with bare hands, as oils and dirt can reduce battery life or cause corrosion. Dispose of the old battery properly in accordance with local regulations for hazardous waste.

Choosing the Correct Replacement Battery

Selecting the right battery is crucial for the optimal performance of your MVMT watch. Most MVMT watches use standard silver oxide button cell batteries, but the specific battery type depends on the model.

Refer to the watch manual, case back inscriptions, or the old battery itself to identify the correct battery code. Common battery types include SR626SW, SR621SW, and SR920SW, among others.

Below is a table summarizing common MVMT watch battery types along with their specifications:

Battery Code Diameter (mm) Height (mm) Voltage (V) Typical Capacity (mAh)
SR626SW 6.8 2.6 1.55 28
SR621SW 6.8 2.1 1.55 18
SR920SW 9.5 2.1 1.55 50

Purchasing a genuine or high-quality replacement battery from a reputable supplier is recommended to ensure longevity and avoid leakage.

Installing the New Battery

Before installation, verify that the new battery matches the specifications of the old one. Using non-metallic tweezers or wearing gloves, position the battery in the compartment with the correct polarity, usually with the positive (+) side facing up.

Secure the battery with the clip or retainer, ensuring it is firmly held but not overly tight to avoid damage. Gently press the battery to confirm it is seated properly.

Avoid touching the battery terminals or internal components with bare hands to prevent contamination. If necessary, clean the battery contacts with a lint-free cloth.

Resealing the Watch Case

After confirming the battery is correctly installed and the watch is functioning, carefully reseal the case back.

For snap-on case backs, align the case back with the watch body and press firmly until it snaps into place. Use a watch press tool if available to apply even pressure and prevent damage.

For screw-down case backs, place the back on the watch and turn it clockwise using the appropriate tool until it is securely tightened. Do not overtighten, as this can strip threads or deform the case.

Check the watch for any gaps and ensure the seal is intact to maintain water resistance. If the watch has a gasket or rubber seal, inspect it for damage or dirt and replace or clean it before closing.

Testing the Watch Functionality

Once the watch case is closed, test the functionality of the watch to ensure the battery replacement was successful.

  • Set the correct time and date.
  • Observe the second hand for smooth movement without hesitation or stopping.
  • Check additional features such as chronograph functions or alarms if applicable.

If the watch does not start or behaves erratically, reopen the case to verify battery placement and contact cleanliness. Repeat the installation steps as necessary or consider professional servicing if issues persist.

Identifying the Correct Battery for Your MVMT Watch

Before beginning the replacement process, it is essential to identify the correct battery model compatible with your MVMT watch. Using an incorrect battery can damage the internal components or lead to improper functioning.

Most MVMT watches use standard button cell batteries, but the exact type can vary depending on the model. Common battery types include:

  • SR626SW (377)
  • SR621SW (364)
  • CR2016 (for some digital or hybrid models)

To determine the precise battery type:

  • Check the user manual or official MVMT website for model-specific information.
  • Open the back case carefully (see next section) and read the battery code printed on the existing battery.
  • If uncertain, consult a professional watch technician to avoid damage.
Battery Type Diameter (mm) Height (mm) Common MVMT Models
SR626SW (377) 6.8 2.6 Most analog MVMT watches
SR621SW (364) 6.8 2.1 Smaller cases or slim models
CR2016 20.0 1.6 Some digital/hybrid styles

      I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

      From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
