The battery is an important component of your watch; it provides the energy needed for it to function. However, a battery's lifespan is not unlimited, which is why you will need to change it approximately every two years. If you are not a professional, we advise you to visit a watch repair shop. at a watchmaker's. Indeed, this procedure, which might be child's play for a watchmaker, can be a real puzzle for novices and requires some tools you may not have.

Changing the battery at home: the different steps

We are here to help you perform this operation under the best possible conditions. However, if your watch is waterproof We strongly advise against changing the battery at home because you will not be able to test the water resistance of your watch once the battery has been changed.

1 - Open the watch

First, you need to determine whether your watch has a snap-on or screw-on case back: 

• To unscrew a Case screwed in tight like our Concordiaequip yourself with a tool Case Adjustable, this tool is also known as a screw-in bottom wrench. Position the tool on the notches on the edge of your Case Then turn gently, the bottom will open.
• If you own a Case For a snap-on case back, use a watchmaker's knife or, if you don't have one, a utility knife. Place one of these sharp tools in the slot. Using leverage, remove the case back from your watch.

2 - Change the battery

Once the Case Once the watch is open, use tweezers (or a pair of pliers) to remove the plastic retaining ring. Then, replace the battery with one that is identical in every way (component, size, voltage). There are three types of batteries: silver oxide, alkaline, and lithium.

• Silver oxide batteries They are recognizable because the letter S is engraved on the battery. This type of battery provides a voltage of 1.55 Volts.
• Alkaline batteries These are the batteries that most closely resemble silver oxide batteries. They are marked with the letter L and deliver a voltage of 1.5V
• Lithium batteries They provide a voltage of 3V and are marked with the letter C. These are often used for watches with more complications which generally require more power.

Finally, there are different sizes of watch batteries: the diameter of a battery is between 5mm and 20mm and the thickness is between 1 and 6mm.

While swapping a silver oxide battery for an alkaline battery in your watch doesn't pose a major risk, it's crucial to note that you should absolutely never install a lithium battery in a watch not designed for that type of battery. Doing so could irreversibly damage your watch.To avoid choosing the wrong model type, refer to the battery compatibility chart.  

3 - Close the watch

Once the battery has been changed, replace the casing ring by positioning the notch of the ring at the level of the crown stem.
