1. Open the Back of a Swiss Army Watch
First, we will need to remove the back of your Swiss Army. For some Swiss Army watches, you’ll need to use a common cover remover. Insert the edge in between the seal and lift the case up.
Other Swiss Army watches have a back case with multiple indentations. For these, you’ll want to use an adjustable watch case opener to safely open your watch. You can also use a pair of needle nosed pliers.
Adjust the size of the watch opener to fit around the back shell of the watch. Line up the nobs with the indentations of the case, and twist the cover off.
