Whether you’re a seasoned watch enthusiast or a first-time DIYer, gaining insight into the battery replacement process empowers you to extend the life of your Movado watch. Stay with us as we guide you through the fundamental steps and tips that will help you confidently tackle this common maintenance task.

Removing the Case Back

To access the battery compartment of your Movado watch, the case back must be carefully removed. Different Movado models feature various case back designs, so identifying the type of case back on your watch is essential before proceeding. The three most common types are snap-off, screw-down, and screw-back with multiple screws.

For a snap-off case back, use a thin, flat tool like a case knife or a fine blade. Insert the blade gently into the small notch on the edge of the case back, and apply slight pressure to pry it open. Take care not to scratch or damage the watch casing.

Screw-down case backs typically have notches around the perimeter. In this case, a specialized case back wrench is required to unscrew the case. Align the wrench with the notches and turn counterclockwise to loosen the back.

Watches with multiple small screws on the case back require a precision screwdriver set. Remove all screws evenly and store them safely to avoid loss.

Identifying and Removing the Battery

Once the case back is removed, you will see the battery secured within the movement. Before touching any internal components, ground yourself to prevent static electricity damage. Use plastic tweezers or a non-metallic tool to avoid short-circuiting.

The battery is usually held in place by a small clip or retaining bar. Carefully release the clip by gently pushing or unscrewing, depending on the design, and lift out the battery.

Note the battery’s model number, which is engraved on its surface. This number is crucial for selecting the correct replacement.

Choosing the Correct Replacement Battery

Using the correct battery ensures optimal performance and longevity of your Movado watch. Most Movado watches use silver oxide batteries, but confirm the exact type by checking the original battery’s markings or consulting the watch’s manual.

Below is a table listing common Movado watch battery types and their specifications:

Battery Model Type Voltage Diameter (mm) Height (mm) Typical Life Span
SR621SW (364) Silver Oxide 1.55V 6.8 2.1 12-18 months
SR920SW (371) Silver Oxide 1.55V 9.5 2.1 12-24 months
SR927SW (395/399) Silver Oxide 1.55V 9.5 2.7 18-24 months

Always purchase batteries from reputable sources to avoid counterfeit or low-quality products that may damage your watch.

Installing the New Battery

Before inserting the new battery, clean the battery compartment gently with a dry, lint-free cloth to remove any dust or residue. Avoid using liquids that could harm the watch movement.

Insert the new battery with the correct polarity, typically the “+” side facing up. Ensure it fits snugly into the compartment without forcing it.

Secure the battery by re-engaging the clip or retaining bar. Double-check that the battery sits firmly and does not move within the compartment.

Reassembling the Watch

After replacing the battery, carefully realign the case back with the watch casing.

  • For snap-off case backs, press firmly around the edges until the back snaps into place. Using a case press tool can help evenly distribute pressure and avoid damage.
  • For screw-down backs, align the threads and turn clockwise until the case back is securely tightened. Avoid overtightening to prevent stripping.
  • For screw-back models with screws, replace all screws evenly and tighten them securely.

Once reassembled, check the watch hands to verify the movement has resumed. If the watch does not start, double-check battery placement and contact a professional if necessary.

Additional Tips for Battery Replacement

  • Always work in a clean, well-lit area with a soft surface to prevent scratches.
  • Avoid touching the new battery with bare hands; use gloves or tweezers to prevent oils from affecting battery life.
  • If you encounter resistance or difficulty removing or replacing parts, consider consulting a professional watch technician.
  • Record the battery replacement date to keep track of future maintenance needs.

These steps ensure a safe and effective battery change, maintaining the precision and appearance of your Movado watch.

Identifying the Battery Type for Your Movado Watch

Before proceeding with the battery replacement, it is essential to identify the correct battery type used in your Movado watch. Different models may require different battery sizes and chemistries, so using the exact replacement ensures optimal performance and prevents damage.

Follow these steps to determine the battery type:

  • Check the Watch Manual: The user manual or warranty booklet often specifies the battery model number.
  • Inspect the Back Case: Some Movado watches have the battery type engraved or printed on the case back.
  • Use a Watch Case Opener: If no visible markings exist, carefully open the back case to read the battery code directly on the battery itself.
  • Consult an Authorized Dealer: Provide your watch model number to a Movado dealer or authorized service center for battery information.
