Swiss Army pocket watches have a reputation for quality and durability, making them a low-maintenance product. One of the few things you will have to do from time to time is replace the battery. Fortunately, there is a very easy way to replace the battery on a Swiss Army pocket watch that will allow you to keep it running for years to come.
Rotate the pocket watch so that it is positioned face down on a flat surface.
Identify the case back type. The back of the watch will either be connected with small Phillips head screws or by a flat-fitting case back.
Remove the case back of the watch. Use a small Phillips head screwdriver to remove the screws on a screw-type case back. For flat-fitting case backs, insert a small flat head screwdriver in between the case back and the case and pry to remove the case back.
Remove the battery. Inside of the case back, use a flat head screwdriver and your fingernail to gently pry up and remove the round watch battery.
Install the new battery into the battery compartment. Replace the case back to its original position by either screwing the case back down to the case or snapping it into place, depending on the type of case back your watch has.
