Movado watches are renowned for their sleek design and reliable craftsmanship, but like all quartz watches, they rely on a battery to function. Over time, this battery will inevitably lose power, making replacement necessary. While it might seem daunting at first, replacing the battery is a straightforward process that can be accomplished with some patience and the proper tools. Knowing what to expect can save you time and prevent potential damage to your watch.

In the following sections, we will explore the essential steps and considerations involved in replacing a Movado watch battery. From identifying the right battery type to safely opening the watch case, this guide will equip you with the knowledge to confidently perform a battery change, ensuring your Movado continues to shine on your wrist.

Opening the Movado Watch Case

To replace the battery in a Movado watch, the first essential step is carefully opening the watch case. Movado watches typically feature either a snap-back case or a screw-down case, and identifying the type is crucial before proceeding.

For a snap-back case, use a thin, flat tool such as a watch case opener knife or a small flathead screwdriver. Locate the small notch along the edge of the case back. Gently insert the tool into the notch and apply light pressure to pry the back off. Take care not to scratch or damage the case or the crystal.

For a screw-down case, you will need a specialized case wrench with adjustable prongs that fit into the grooves on the back. Align the prongs with the grooves, then turn counterclockwise to unscrew the back. This requires a steady hand to avoid slipping and scratching.

If you are unsure about the case type or uncomfortable opening the case yourself, consider visiting a professional watchmaker to avoid potential damage.

Removing the Old Battery

Once the case back is removed, the battery is exposed, often held in place by a small clip or cover. Before proceeding, note the battery’s orientation to ensure proper installation of the new one.

To remove the old battery:

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

Avoid touching the movement or other delicate components inside the watch. If the battery is stuck, do not force it; instead, gently maneuver it free to prevent damage.

Choosing the Correct Replacement Battery

Selecting the right battery is critical to ensure the watch functions correctly and maintains its water resistance. Movado watches commonly use silver oxide batteries, but the exact type depends on the specific model.

Refer to the battery code printed on the old battery or consult the user manual. Some common battery types for Movado watches include:

Battery Code Voltage Diameter (mm) Height (mm) Common Models
SR621SW (364) 1.55 V 6.8 2.1 Small Movado quartz watches
SR920SW (370) 1.55 V 9.5 2.1 Mid-sized Movado models
SR927SW (395/399) 1.55 V 9.5 2.7 Larger Movado watches

Always purchase batteries from reputable suppliers to guarantee authenticity and performance.

Installing the New Battery

After obtaining the correct replacement battery, installation must be done carefully to avoid damaging the watch’s internal components.

  • Using plastic tweezers, place the new battery into the compartment in the same orientation as the old one.
  • Ensure the battery sits flush and the positive (+) side faces the correct direction.
  • Gently secure the battery with the retaining clip or cover, making sure it holds the battery firmly without applying excessive force.
  • Avoid touching the battery surface with bare fingers, as oils can reduce battery life.

Once installed, check the watch to verify it is running before proceeding to close the case.

Closing the Watch Case

Properly sealing the watch case is essential to maintain water resistance and protect the internal mechanism.

For a snap-back case:

  • Align the case back with the watch body, ensuring any notches or grooves line up correctly.
  • Press down evenly around the edges using your thumbs or a watch press tool until it snaps securely into place.
  • Avoid pressing on the crystal to prevent damage.

For a screw-down case:

  • Position the case back correctly and start turning it clockwise by hand.
  • Use the case wrench to tighten the back firmly but avoid overtightening, which could strip the threads or damage the gasket.

After closing, inspect the edges to confirm there are no gaps. If your Movado watch is water-resistant, it is advisable to have the seals checked or replaced periodically by a professional.

Testing and Final Checks

Once the battery is replaced and the case is closed, perform the following checks:

  • Verify the watch hands are moving correctly and that all functions (e.g., date, chronograph) operate properly.
  • Set the time and date as needed.
  • If your Movado watch is water-resistant, avoid submerging it immediately after battery replacement. Consider professional pressure testing if you require full water resistance.
  • Monitor the watch over the next 24 hours to ensure consistent performance.

Taking these steps ensures your Movado watch continues to operate accurately and maintains its elegant appearance.

Identifying the Correct Battery Type for Your Movado Watch

Before beginning the battery replacement process, it is essential to determine the specific battery model your Movado watch requires. Using the correct battery ensures optimal performance and prevents damage to the watch’s internal components.
