You can change a Movado watch battery yourself if the case back is not sealed, but most Movado models require a professional

Movado watches fall into two categories: those with screw-off case backs and those with sealed, glued, or press-fit backs. If your Movado has a screw-off back, you can change the battery at home with basic tools. If the back is sealed or press-fit, opening it risks damaging the watch, and Movado or an authorized service center should do the work instead. The first step is determining which type you have.

Most Movado dress watches and many sport models use sealed case backs that require professional service. Museum watches, some Movado Bold models, and certain vintage pieces have screw-off backs. Look at the back of your watch: if you see a thin seam all the way around the edge and small notches or grooves, it likely unscrews. If the back appears smooth and featureless, it is sealed.

Key Takeaways

  • Screw-off case backs can be opened at home with a case back opener tool, but sealed or press-fit backs should only be opened by a professional to avoid damage.
  • Movado battery replacements typically cost between $50 and $150 at an authorized service center, depending on the model and whether the watch needs additional service.
  • If you open the case yourself, note the battery type and orientation before removal so you install the replacement correctly.
  • After replacing the battery, test the watch for 24 hours before closing the case back permanently to confirm it is keeping time.

Identifying your Movado case back type

Run your fingernail or a soft cloth around the edge of the case back. A screw-off back will have a visible seam and often small notches or a groove pattern. A sealed back will feel smooth and continuous with the case. If you are still unsure, check your watch documentation or contact Movado customer service with the model number—they can confirm in one call.

Sealed case backs are common on Movado's most popular lines because they offer better water resistance and a cleaner aesthetic. Opening one without the proper equipment can crack the back, damage the gasket, or misalign the movement. Even if you succeed in opening it, reassembling it correctly is difficult without a press tool.

Tools and materials you will need for a screw-off back

A case back opener (also called a case knife or case wrench) is essential. These cost $8 to $20 and come in two main types: a flat-blade tool with notches that fit into the grooves on the back, or a rotating wrench with adjustable pins that grip the back's edge. The notched blade is simpler for beginners. You can find them at jewelry supply stores, watch retailers, or online.

You will also need the correct replacement battery. Movado watches typically use SR batteries (silver oxide) in sizes like SR626SW, SR927SW, or SR920SW. Check your watch documentation or the old battery itself for the exact model number. Have the new battery on hand before you open the case. You will also want a small bowl or tray to hold tiny parts, a soft cloth, and a magnifying glass if your eyesight needs it.

Step-by-step process for changing the battery

Place your watch face-down on a soft cloth to protect the crystal. Locate the notches or grooves on the case back. Insert the case back opener tool into the notches and turn counterclockwise slowly—do not force it. The back should unscrew after a few turns. If it does not budge after gentle pressure, stop and take the watch to a professional; forcing it can strip the threads.

Once the back is off, note the battery's position and orientation. Take a photo with your phone if it helps. Gently lift the old battery out using a plastic tool or the edge of a plastic card—never use metal tweezers directly on the battery, as this can cause a short. If the battery is stuck, a tiny drop of isopropyl alcohol around the edge can help loosen it.

Before installing the new battery, check that the movement and gasket look clean and dry. If you see corrosion or moisture, do not proceed—take the watch to a professional. Insert the new battery with the positive side facing up (the side marked with a +). Press it gently into place until it sits flat. Do not force it; it should settle with light pressure.

Screw the case back on by hand first, then use the case back opener to tighten it firmly but not excessively. Over-tightening can crack the back or strip the threads. The back should be snug enough that you cannot turn it by hand, but you should not need to explore hard pressure with the tool.

Testing your watch after battery replacement

Wear the watch for 24 hours and check that it is keeping accurate time. Compare it to your phone or a reliable clock every few hours. If the watch stops, runs fast, or runs slow, the battery may not be making proper contact, or the wrong battery type may have been installed. Open the case again and confirm the battery is seated correctly and that you used the correct model number.

If the watch still does not work after you have checked the battery twice, the movement may have a problem unrelated to the battery. At that point, a professional service is needed.

When to take your Movado to a professional

If your case back is sealed, press-fit, or glued, take the watch to an authorized Movado service center or a certified watch repair shop. Movado maintains a list of authorized service centers on their website, searchable by location. Authorized centers have the proper equipment and can also inspect the movement, clean the case, and replace the gasket if needed.

Professional battery replacement typically takes one to two weeks and costs between $50 and $150, depending on the model and whether additional service is performed. Some shops charge a flat rate for battery replacement; others charge separately for opening the case, replacing the battery, and closing it. Ask for a quote before you leave the watch.

Common mistakes to avoid

Do not use a regular screwdriver or knife to pry open a sealed case back. This will scratch or crack the back and damage the watch. Do not touch the movement or any internal parts with your bare hands; oils from your skin can cause corrosion. Do not install the battery upside down; the positive side must face up. Do not over-tighten the case back; this can crack it or strip the threads.

Do not assume all Movado watches have the same battery type. Always check the old battery or your documentation before buying a replacement. Installing the wrong size battery can prevent the case back from closing properly or cause the battery to make poor contact with the movement.

Frequently Asked Questions

How do I know what battery my Movado uses?

The easiest way is to open the case back (if it unscrews) and look at the old battery itself—the model number is printed on it. If the back is sealed, check your watch documentation or contact Movado with your model number. Most Movado watches use SR626SW or SR927SW batteries.

Can I use a regular alkaline battery instead of a silver oxide battery?

No. Movado watches are designed for silver oxide batteries, which have a different voltage and discharge curve. An alkaline battery will not fit properly, may damage the movement, or will not power the watch correctly. Always use the exact battery type specified.

What if I accidentally scratched the case back while opening it?

Minor scratches can often be polished out by a professional. If the back is cracked or the threads are damaged, it will need to be replaced. An authorized Movado service center can order a replacement back and install it.

How long does a Movado watch battery last?

Most Movado batteries last two to three years with normal wear. If your watch stops within a few months of a battery replacement, the battery may be defective or the movement may have a problem. Contact the shop where you had it replaced.

Is it safe to wear my Movado in the shower after changing the battery?

If you changed the battery yourself and the case back unscrews, the watch is not waterproof until a professional reseals it. If the back was originally sealed, take it to an authorized service center to have the gasket replaced and the case back resealed before exposing it to water.
