Tools and Materials Needed for Battery Replacement

Before beginning the battery replacement process for your MVMT watch, it is essential to gather the necessary tools and materials. Having the right equipment ensures a smooth and damage-free procedure.

  • Replacement battery: Confirm the exact battery model compatible with your MVMT watch. Most MVMT watches use standard silver oxide coin cells, but verifying the specific type is critical.
  • Watch case opener: This tool helps safely remove the watch back without scratching or damaging the casing. A case knife or case wrench is commonly used.
  • Tweezers: Non-metallic or anti-magnetic tweezers are preferred to handle the battery, preventing short circuits.
  • Small screwdriver set: Depending on your watch model, you may need precision screwdrivers to access the battery compartment.
  • Soft cloth or pad: To protect the watch face and components during the replacement.
  • Magnifying glass (optional): Useful for inspecting tiny parts and ensuring correct battery placement.

Having these tools ready can significantly reduce the risk of damage and make the replacement process more efficient.

Step-by-Step Procedure to Replace the Battery

Replacing the battery in an MVMT watch involves careful handling and attention to detail. Follow these steps precisely to avoid complications:

  1. Prepare your workspace: Work on a clean, flat surface with good lighting. Lay down a soft cloth to prevent scratches.
  2. Remove the watch back:
  • Identify the type of back cover—snap-off or screw-down.
  • For snap-off backs, gently insert the case knife or opener into the small gap and pry it open.
  • For screw-down backs, use the case wrench to unscrew counterclockwise.
  1. Locate and remove the battery:
  • Observe the battery placement and note the orientation (positive and negative sides).
  • Use tweezers or a small screwdriver to carefully lift the battery out. Avoid touching other components.
  1. Insert the new battery:
  • Place the new battery in the same orientation as the old one.
  • Ensure it sits flush in its compartment without forcing it.
  1. Test the watch:
  • Before sealing, check if the watch is functioning properly.
  • If it doesn’t start, re-check battery placement and contacts.
  1. Close the watch back:
  • For snap-off backs, press the cover firmly until it snaps into place.
  • For screw-down backs, screw clockwise until secure but avoid overtightening.
  1. Clean the watch: Wipe off fingerprints or smudges with a soft cloth.
