Changing the battery in a watch may seem like a daunting task, but with the right tools and a little know-how, it can be done relatively easily. The most important thing is to have the right tools for the job. You will need a small screwdriver, a watch band remover, and a new battery.
Once you have the right tools, you can begin by removing the watch band. To do this, use the watch band remover to push down on the spring bars that hold the band in place. Once the spring bars are released, you can pull the band off of the watch.
