Tools Needed for Replacing the Battery

Replacing the battery in a MVMT watch requires precision and care, so having the right tools on hand is essential. Using improper tools can damage the watch case or internal components, so it is recommended to work on a clean, flat surface with adequate lighting.

Key tools include:

  • Case back opener or a small, flat precision screwdriver
  • Tweezers (preferably non-magnetic)
  • Plastic pry tool or case knife
  • Replacement battery (check the exact battery type before purchase)
  • Soft cloth or watch holder to protect the watch face and case
  • Optional: magnifying glass for better visibility of small components

Having these tools prepared will streamline the battery replacement process and reduce the risk of accidental damage.

Step-by-Step Process to Change the Battery

Begin by laying the watch face down on a soft cloth to prevent scratches. Identify the type of case back your MVMT watch has — most commonly, these watches feature a snap-off case back, but some may have screws.

For snap-off backs:

  • Locate the small indentation or lip on the edge of the case back.
  • Insert the case knife or flat precision screwdriver into this groove carefully.
  • Gently pry the back open, applying slow, consistent pressure to avoid bending the case.

For screw-down backs:

  • Use an appropriate case back opener tool that fits the grooves.
  • Turn counterclockwise to unscrew the back carefully.

Once the back is removed, you will see the battery held in place by a small clip or metal arm. Before touching the battery, note the battery type and orientation.

To remove and replace the battery:

  • Use tweezers to lift the clip gently if needed.
  • Remove the old battery without touching other components.
  • Insert the new battery in the same orientation (usually with the positive side facing up).
  • Secure the battery clip back in place.

After the new battery is installed, check the watch’s function by observing the second hand movement or digital display if applicable.

Finally, replace the case back:

  • For snap-off backs, align the case back and press firmly until it snaps into place.
  • For screw-down backs, screw it back on securely using the case back opener.

Battery Types Commonly Used in MVMT Watches

MVMT watches typically use button cell batteries, also known as coin cells. The exact battery model varies based on the watch design and movement type. It is crucial to verify the battery code printed on the old battery or consult the watch manual to ensure compatibility.

Battery Model Voltage Diameter (mm) Common MVMT Watch Models
SR626SW (377) 1.55 V 6.8 Classic Series, Voyager
SR621SW (364) 1.55 V 6.8 Minimalist Series
CR2016 3 V 20 Digital or hybrid models (less common)

Using the correct battery ensures optimal performance and prevents damage to the watch’s circuitry.

Precautions and Tips for Battery Replacement

When changing the battery, consider the following best practices:

  • Avoid touching the battery terminals with bare fingers to prevent corrosion from oils and dirt.
  • Work in a static-free environment to protect the watch’s movement from electrostatic discharge.
  • Do not force the case back when closing it; ensure it aligns properly to maintain water resistance.
  • If the watch has a water resistance rating, consider having the seal or gasket checked or replaced to maintain its integrity.
  • Dispose of the old battery responsibly, following local regulations for battery recycling.

If unsure about any step or if the watch is particularly valuable or delicate, it is advisable to seek professional watch repair services.

Preparing to Change the Battery in Your MVMT Watch

Before beginning the battery replacement process, gather the necessary tools and ensure you have a compatible replacement battery for your specific MVMT watch model. Most MVMT watches use standard button cell batteries, commonly the SR626SW or similar, but it is essential to verify the exact type to avoid compatibility issues.

Tools and materials needed:

  • Precision screwdriver set (typically a small Phillips or flathead depending on the watch back)
  • Case back opener tool or a thin, sturdy blade
  • Tweezers (preferably non-metallic to avoid short-circuiting)
  • Replacement battery (check watch manual or back case for type)
  • Soft cloth or mat to prevent scratching
  • Magnifying glass (optional for visibility)

Preparation steps:

  • Work on a clean, flat surface with adequate lighting.
  • Place the watch face down on the soft cloth to protect the glass.
  • Discharge any static electricity from your hands by touching a grounded metal object.
  • Ensure you handle the watch and battery with clean hands or gloves to prevent contamination.

Removing the Case Back of an MVMT Watch

MVMT watches typically have snap-on or screw-down case backs, and the removal method varies accordingly.

Snap-on case backs:

  • Look for a small indentation or notch along the edge of the case back.
  • Insert a case back opener tool or a thin blade into the notch carefully.
  • Gently twist or pry to pop the case back off without applying excessive force to avoid damaging the watch.

Screw-down case backs:

  • Identify the small grooves or notches around the perimeter of the case back.
  • Use a suitable case back wrench or a precision screwdriver designed for screw-down backs.
  • Turn counterclockwise to unscrew the back.
  • Keep the case back and screws in a safe place for reassembly.

Important considerations:

  • Avoid using excessive force to prevent scratching or deforming the case.
  • If resistance is high, reassess the tool and technique to prevent damage.
  • Some MVMT models may require specific tools; consult the manufacturer if unsure.

Removing and Replacing the Battery

Once the case back is removed, proceed with the battery replacement carefully.

Steps to remove the old battery:

  • Identify the battery compartment; note the battery orientation (positive and negative sides).
  • Use tweezers or a small flathead screwdriver to gently lift the battery out.
  • Avoid touching other internal components to prevent damage.

Inserting the new battery:

  • Compare the new battery with the old one to confirm size and type.
  • Place the new battery in the compartment, ensuring the correct polarity.
  • Press the battery down gently until it is securely seated.
  • Observe any battery clips or holders and ensure they are properly engaged.

Battery polarity reference:

Symbol Meaning
“+” Positive side up
“−” Negative side down

Confirm the polarity by checking the markings on the battery and battery holder.

Reassembling the Watch and Testing

After replacing the battery, reassemble the watch carefully to maintain its water resistance and structural integrity.

Steps for reassembly:

  • Clean the case back and gasket with a soft cloth to remove dust or debris.
  • Inspect the gasket (rubber seal) for damage; replace it if cracked or worn to preserve water resistance.
  • Align the case back correctly with the watch case.
  • For snap-on backs, press firmly and evenly until it clicks into place.
  • For screw-down backs, screw it back carefully without cross-threading.

Testing the watch:

  • Turn the watch over and check that the second hand is moving or the digital display is functioning.
  • Set the time and date to confirm operational status.
  • If the watch does not start, recheck battery orientation and contacts.
  • Perform a water resistance test if possible, especially if the watch is used in wet conditions.

Additional Tips for Maintaining Your MVMT Watch Battery Life

Proper care and maintenance can extend the life of your MVMT watch battery and ensure optimal performance.

  • Avoid exposing the watch to extreme temperatures which can degrade battery life.
  • Keep the watch away from strong magnetic fields which may interfere with movement.
  • Remove the watch during activities that may cause shocks or vibrations to prolong internal component life.
  • Schedule battery replacements proactively every 1-2 years or as recommended by MVMT.
  • If your watch has additional features such as chronographs or alarms, use them sparingly to conserve battery power.

Following these guidelines will help maintain your MVMT watch’s accuracy and longevity after a battery replacement.
