Chapter in this post:
The term "watch battery" basically means a normal button cell that is built into the wristwatch. You can quickly see why these batteries are called "button cells" by their flat and round design. Most wristwatches use such button cells as batteries, as their flat design means that they do not unnecessarily increase the thickness of the watch. In addition, the batteries offer a long service life, which is guaranteed by the chemical composition of the cell.
The two decisive reasons why button cells are installed in watches are the very low self-discharge of the cells and the constant output voltage, which remains for years. With many batteries, the cell voltage decreases right at the beginning of use and thus continues to decrease over the service life. In the case of watch batteries, the voltage only kinks towards the end of their service life. This ensures that the clock is "accurate" for as long as possible.
Making a list of the watch models and the matching watch battery would go beyond the scope of my possibilities. Nevertheless, I am happy to offer my advice here when it comes to finding the right button cell. To find the right battery, it would be very good if you could tell me the exact name of the old battery. With this I can usually find a button cell of the same construction that fits into the watch. The exact name of the watch model would also help me with my research.
There are some types of batteries that are particularly common in watches from Seiko, Casio, Citizen, Esprit, Swatch or Timex. These are usually found in button cell sets that contain a selection of frequently used button cells.
Here is a selection of frequently used button cells with a direct link to Amazon to order there:

In my opinion, a good option for the household is button cell sets, which contain many different types of batteries. I have bought sets of this kind several times and have been able to equip my kitchen scales as well as my car key and a remote control with them without any problems. It also includes button cells for wristwatches, but since I use an Apple Watch, I don't need them for my watch. But here are a few sets for you and the types of batteries they contain:
Opening and closing the watch cover and replacing the battery can be very fiddly without the right tools. For this reason, here is a recommendation for a cheap but good watchmaker's set that also helps if you want to shorten the bracelet:
I have a little recommendation for people who would like to read more: Here I have recorded in an article where the technical differences between the CR2032, CR2025 and CR2016 batteries lie.
