Changing the battery in your watch

Has your watch stopped, started running slow, or does the display seem dimmer? Its battery may have reached the end of its life. To replace it without risking damage to the case, the movement, or the waterproof seal, it’s best to have a professional perform the repair.

MATY’s expert jewelers and watchmakers can replace the batteries in many MATY and other brand-name watches. Depending on the model, whether the case needs to be opened, and the desired level of water resistance, the service is performed directly in the jewelry store or sent to a watch repair shop.

In short: Get your watch battery replaced at MATY

• Battery replacement can be done at a MATY jewelry store if the case can be opened on-site.

• MATY watches, as well as watches from certain other brands, may be covered.

• A simple battery replacement replaces the battery, but does not guarantee that the device will remain watertight.

• To maintain water resistance—especially on a watch rated for at least 5 ATM—specific servicing and inspection are recommended.

• Some watches must be sent to a MATY service center or directly to the manufacturer.

• The listed price is €10 for a simple battery replacement and €34 for a battery replacement that includes resealing.

• It is best not to leave a dead battery in a watch for too long, as a leak could damage its mechanism.

How much does it cost to replace a watch battery?

The price depends mainly on the type of repair and whether or not the watch’s water resistance needs to be maintained.

These prices and turnaround times are approximate. The final cost depends on the model, brand, and condition of the watch, as well as whether the case can be opened safely.

When a service call must be performed directly by the brand, the brand sets its own rate. You should also expect a longer turnaround time.

Where can I get a watch battery replaced?

You can bring your watch to a MATY jewelry store so that an expert can examine the case and determine what kind of service is needed.

If the watch case back can be opened using the tools available at a jewelry store, a simple battery replacement can be performed on-site.

In certain situations, however, it will need to be taken to a watch repair shop:

• The case cannot be opened at a jewelry store;

• The watch needs to be tested for water resistance;

• Its design requires special equipment;

• His condition requires further evaluation;

• its manufacturer requires a specific repair;

• It cannot be handled directly by MATY experts.

If the MATY workshop is unable to service the model in question, the watch can be sent to the manufacturer. The cost and turnaround time are then determined by the manufacturer.

How does a battery replacement work at MATY?

Service always begins with an inspection of the watch. This initial inspection helps identify the type of case, the water resistance rating, and any special features of the model.

1. Take your watch to a jewelry store

Show your watch to a MATY advisor. If you have the warranty, the instruction manual, or information about the model number, please bring those with you as well.

2. An expert inspects the housing

The expert examines the back of the watch and determines whether it can be opened at a jewelry store. He also checks whether it needs to have its water resistance maintained or requires special care.

3. The battery is replaced at a jewelry store whenever possible

If the model can be serviced on-site and you choose a simple replacement, the old battery will be removed and replaced with a compatible battery.

4. The watch is sent to the repair shop if necessary

When the water resistance needs to be checked or the case cannot be opened at a jewelry store, the watch is sent to a watch repair shop.

5. The brand may be available on certain models

If the MATY service centers are unable to perform the repair, the watch can be sent directly to the manufacturer. The cost and turnaround time will then depend on the manufacturer's policies.

6. You will be notified of the coverage

The route, price, and estimated delivery time will be provided to you based on the service you select for your watch.

MATY Watch or Brand-Name Watch: What Are the Differences in Coverage?

MATY jewelry stores can service both MATY watches and watches from other brands. However, whether the battery can be replaced depends on the case design and the manufacturer’s service guidelines.

Even if a watch was not purchased at MATY, you can still bring it to a jewelry store to see if it can be repaired.

Simple battery replacement or replacement with a seal: What's the difference?

Replacing a battery requires opening the back of the watch. This procedure may affect the watch's water resistance, particularly if the gasket is displaced, worn, or improperly repositioned.

How to Change a Battery

The simple procedure involves opening the case, replacing the battery, and then closing the watch.

This service may be suitable for a non-water-resistant watch or a model that will not be exposed to water. However, it does not include the procedures necessary to ensure that the watch remains water-resistant after it has been opened.

Even if the watch originally had a water resistance rating, this should not be considered a guarantee after a simple battery replacement.

Replacing the battery while maintaining water resistance

This service includes battery replacement and the necessary checks to ensure the watch is watertight.

It is especially recommended if you wear your watch:

• in the rain;

• during a sporting activity;

• in a humid environment;

• near the water;

• for swimming, provided that it is watertight and the manufacturer's instructions permit it.

When the watch is rated at 5 ATM or higher, MATY recommends taking it to a service center to have the battery replaced while maintaining its water resistance.

The gasket may also need to be inspected or replaced, depending on its condition. A water-resistant watch does not automatically maintain its performance throughout its lifetime: gaskets age and can become brittle due to heat, impacts, or manipulation of the crown.

Which service should you choose based on the watch's water resistance?

Water resistance ratings expressed in ATM indicate the level of water resistance specified by the manufacturer. They should not be interpreted as the actual depth at which the watch can be used under all circumstances.

These guidelines are general in nature. Permitted uses vary depending on the manufacturer, model, age of the watch, and condition of its gaskets. Always consult the instruction manual before exposing the watch to water.

Why not change a watch battery yourself?

Changing a battery may seem simple, but opening a case requires the right tools and a good understanding of its design.

An inappropriate action can cause a variety of problems.

Scratch or dent the bottom of the case

Clip-on and screw-on cases cannot be opened with the same tools. Using a knife, screwdriver, or unsuitable pliers can leave deep marks on the case.

Uneven pressure can also distort the bottom and make it harder to close.

Damage the seal

The gasket is usually located between the bottom and the housing. It can get pinched, displaced, or cut during opening and closing.

A watch that appears to be properly closed may still allow moisture to enter without it being immediately noticeable.

Touching the internal components

The movement of a quartz watch contains delicate and sensitive parts. Improper handling can damage a contact, a coil, or another component.

Dust, fingerprints, and small particles that get inside the case can also interfere with the watch's operation.

Installing an unsuitable battery

Not all batteries have the same dimensions or specifications. An incompatible battery may not work properly, may discharge quickly, or may damage the contacts.

Failure to close the case properly

A snap-on bottom must be repositioned with precision and the appropriate amount of pressure. A screw-on bottom, on the other hand, must be properly aligned.

If the clasp isn't closed properly, the watch may be exposed to dust and moisture.

Inability to verify watertightness

Even when the battery appears to be installed correctly, it is not possible to guarantee the watch's water resistance without the proper testing equipment.

Having a jeweler and watchmaker perform the service ensures that the case is protected, the correct battery is selected, and the watch is sent to a repair shop when necessary.

When should you replace a watch battery?

A quartz watch can generally run for several months or several years on the same battery. Its battery life depends on the movement, the functions used, and the manufacturer's recommendations.

Unless otherwise specified by the manufacturer, MATY recommends replacing the battery approximately every 18 months. This frequency is only a guideline: some batteries last longer, while watches with power-intensive features may require more frequent replacement.

There are several signs that may indicate the battery is nearing the end of its life:

• the watch stops;

• It restarts and then stops again;

• she's falling behind;

• the digital display becomes dim or flickers;

• some functions no longer work properly;

• On some models, the second hand moves at irregular intervals;

• The battery hasn't been replaced in a long time.

A watch that has stopped isn't always just a battery issue. If it was subjected to a shock, got wet, or showed signs of malfunction before stopping, further diagnosis may be necessary.

What are the risks of leaving a dead battery in a watch?

A battery that has reached the end of its life should not be left in the case indefinitely, even if the watch is no longer being worn.

Over time, a worn-out battery may leak and release a corrosive substance. This substance may come into contact with the movement’s contacts and components.

The consequences can be more serious than just a shutdown:

• oxidation of the contacts;

• malfunction of the electronic circuit;

• deterioration of the movement;

• replacement of several components;

• longer and more expensive repairs;

• It is impossible to restore a severely damaged watch to working order.

If a watch has been stopped for a long time, it's best to have it inspected before installing a new battery. A professional can check the condition of the battery compartment and look for any signs of oxidation.

How can I tell if the problem is really caused by the battery?

When a quartz watch stops, it is often due to a dead battery, but there are other possible causes.

The problem may stem from:

• a loose electrical connection;

• from an old battery that had leaked;

• a damaged movement;

• a poorly positioned crown;

• from an impact;

• water infiltration;

• mechanical wear;

• a defective electronic component.

A battery that drains abnormally quickly may also indicate a power consumption issue with the movement.

The inspection will determine whether a simple battery replacement is sufficient or whether a watch repair assessment is necessary.

What should I do if the watch doesn't work after changing the battery?

A watch that does not start running again after a new battery is installed likely has another problem.

There are several possible explanations:

• the battery is not suitable for the movement;

• it was positioned incorrectly;

• the contacts are oxidized or damaged;

• the old battery leaked;

• the movement is blocked;

• the crown or its mechanism is defective;

• the electronic circuit is damaged;

• The watch has been subjected to an impact or water ingress.

Avoid opening and closing the case repeatedly or tampering with the movement. Take the watch to a professional for a diagnosis.

Depending on the model and the nature of the problem, the watch may be inspected at a jewelry store, sent to a MATY repair shop, or forwarded to the manufacturer.

Do I need to make an appointment to replace a battery?

You can visit a MATY jewelry store to have your watch inspected. However, the terms of service and availability may vary depending on the store, the model, and the type of service required.

If you have a brand-name watch, a water-resistant watch, or a specific model, we recommend contacting the jewelry store in advance. The staff will be able to tell you:

• if the model can be viewed on site;

• if workshop repairs are likely;

• What documents to bring;

• How long should I expect it to take?;

• whether it's best to make an appointment.

Even with an appointment, some will need to be kept and then sent to the repair shop. An inspection of the housing is still necessary to determine the appropriate course of action.

What types of watches may need a battery replacement?

Battery replacement mainly applies to quartz watches. This type of movement uses electrical energy supplied by a battery to measure time and move the hands or power a display.

Depending on the model, the service may involve a watch:

• analog quartz;

• foxglove;

• for women;

• for men;

• for children;

• waterproof;

• fully snapped shut;

• screw-on bottom;

• MATY;

• from another brand.

Smartwatches typically run on a rechargeable battery rather than a traditional battery. How long they last therefore depends on the model and manufacturer.

Please note: Not all watches have a battery.

A watch that has stopped doesn't necessarily need a new battery. How it works depends on the movement inside it.

The quartz watch

It runs on a battery that provides the power needed for the movement. This type of watch is the one most commonly serviced for battery replacement.

The Automatic Watch

It is powered by wrist movements, which gradually wind its mechanism. It may stop if it is not worn for a certain period of time, but this does not indicate a malfunction.

It generally does not use a traditional battery.

The mechanical watch with manual winding

Its mechanism must be wound regularly using the crown. It operates without a battery.

The Solar Watch

It captures light through a cell built into the dial and stores the energy in a rechargeable battery. When it stops, it may need sufficient exposure to light.

The smartwatch

It typically uses a rechargeable battery and must be recharged using a cable or a compatible charging dock.

If you are unsure of your watch's movement, a MATY advisor can help you identify it and direct you to the appropriate service.

How can I extend the battery life?

A few good habits can help protect your watch and allow you to spot unusual battery drain more quickly.

Follow the manufacturer's recommendations

Battery life varies depending on the watch's movement and functions. An alarm, backlight, chronograph, or digital display may consume more power.

Refer to the manual for recommendations specific to your model.

Avoid extreme temperatures

Prolonged exposure to extreme heat or cold can affect the battery and the movement's operation.

In particular, avoid leaving your watch on a radiator for long periods of time, behind a window in direct sunlight, or in a vehicle subject to extreme temperature fluctuations.

Have an abnormally rapid discharge checked

If several batteries in a row run out of power within a short period of time, the problem may be caused by movement or an electronic component.

Simply replacing the battery more often won't be enough: a watch inspection will help identify the cause.

Do not leave the watch stopped for too long

If a quartz watch stops, have it checked right away—don't wait several months or years. This will reduce the risk of a dead battery leaking inside the case.

Using the Features Correctly

Repeated use of the buttons, lights, or alarms may increase power consumption on certain models.

Use the functions as described in the instruction manual, and have the watch inspected if any of them stop working properly.

What other services should you plan for when replacing a battery?

Replacing the battery can be an opportunity to check the watch's overall condition and prevent other malfunctions.

Depending on the model, its age, and how it is used, several options may be considered.

Leak Testing

This inspection is particularly important if the watch is exposed to water. It ensures that the properly closed case maintains the expected level of protection.

Checking or replacing the gasket

Seals age over time and can lose their flexibility. Their condition should be checked after opening the housing, especially if a watertight seal must be maintained.

Inspecting the clasp and the bracelet

A loose strap, a weakened clasp, or a defective clasp increases the risk of losing the watch.

A quick inspection can help you spot these signs of wear before a part breaks.

Adjusting or Changing the Strap

The strap can be shortened, adjusted, or replaced depending on its type and availability. A new battery can thus be installed along with a strap adjustment to ensure the watch fits comfortably.

Checking the Crown

The crown is used to set the time and, depending on the model, the date or other functions. If it is difficult to turn, does not stay in place, or no longer allows for adjustment, a diagnostic check is recommended.

Cleaning the Case

Proper cleaning removes surface dirt that has accumulated on the case and bracelet. It must take into account the watch’s materials, finishes, and water resistance.

Movement Assessment

If the watch is running slow, stops repeatedly, or uses up batteries too quickly, a more thorough inspection of the movement may be recommended.
