Do All Watches Use the Same Battery?
Wristwatches can be very important in making the right impression. Even though we now have smartphones that can tell us the time at one touch, watches have not lost any of their importance over time. In fact, they remain an integral part of any outfit.
But taking care of a watch is as necessary as buying the right brand of watch.
Watches are available with mainly two types of movements- quartz and mechanical. Quartz watches are the more popular of the two. This is because they are more accurate and can be mass-produced easily, making them cheap. These watches are powered by a battery. And batteries are perhaps the most important part of a watch’s mechanism. But are they really that simple to understand?
Do All Watches Use the Same Battery?
To put it in one word, no.
You would think that something as minuscule as a battery would be a simple thing, but we assure you, it is not. A watch battery looks just like a little button, which is why they are also called button cells. However, this tiny thing is a very complex thing to understand.
All watches do not even use the same type of battery. Watch batteries differ in a lot of things, like the size. For example, the most common watch battery dimensions are 9.5 mm in diameter and 2.1 mm in height (battery code 371), and 6.8 mm in diameter, and 2.6 mm in height (battery code 372).
Different Types of Batteries
As mentioned before, watch batteries come in a lot of different sizes. They differ in height as well as diameter. They are also given codenames accordingly. These sizes are usually mentioned in the user manual of the watch. You just need to know the battery code to get an accurate replacement.
You can refer to the following chart for battery size and code conversion:

Traditional watch batteries are made of basically three kinds of materials. They differ in voltage and durability.
Alkaline Watch Batteries
Alkaline watch batteries possess a power of 1.5V. These are the cheapest watch batteries in the market. Since they do not last very long, they are only good for shorter uses.
Silver-Oxide Watch Batteries
These batteries have a power of 1.55V. These are slightly better than alkaline batteries in volt power and they also tend to last longer. This is also why they are the most common type of watch battery used today.
Lithium Watch Batteries
Lithium batteries are the best quality watch batteries available in the market today. They are used extensively in the making of premium, luxury brand watches. But since they last the longest, they are also the most expensive.

the bottom line:
As you can see, watches are equipped with different kinds of batteries. And we have just scratched the surface. This is why we would say that it is best to get your battery replaced at a watch shop or at a jewelry store. After all, it is a very delicate thing, and getting it wrong can disrupt the functioning of your watch.
That being said, it is perfectly reasonable to be curious about the parts of your wrist buddy. You do have a right to know what makes up the different parts of your things, so why should you not be inquisitive about these cells? We hope that the article helped in answering some of the questions you might have.
