Use plastic tweezers or your fingers to insert a new battery

One of the reasons why I made this post is because in some guides people used metal tweezers to insert a new battery. This will short it and potentially damage it which can result in watch damage as well.

Close the metal battery retainer and clip it back to the plastic clip

Next, we will read what is written on the battery sticker and do so

On the second photo you can see how to use metal tweezers to connect (-) to AC. AC is marked with the arrow on the metal shroud of the watch movement

It is not bad idea to flip the watch afterwards to make sure that it is working. Be careful that the movement doesn’t fall out of the case

For some reason on lots of tutorials people are just ignoring the note on the battery sticker. It is there for a reason so that is why this step is documented here

Returning sticker back to its place so that the next person who will be doing the replacement know what to do
