Can You Help Extend the Life of Your Watch Battery?
There are some things you can do to extend the life of your watch battery. If you wear a certain watch only on special occasions, you can pull out the crown to stop the watch from ticking while it’s not being used. You will have to reset the proper time when you do want to wear it again, but stopping the ticking helps extend battery life.

If you have a chronograph watch or a watch with an alarm function, disabling those functions, especially if you do not use them, will also extend your watch’s battery life.
