Seiko watches have maintained popularity because they can complement business attires as well as more casual looks. However, just like any other watch brand, the batteries in a Seiko will not last forever. When the time comes to replace the battery, you can either take it to a watch repair shop, or you can save money and replace the battery yourself. Replacing a Seiko watch battery is a meticulous process, though, which demands the utmost caution.
Lay the face of your Seiko watch on a cloth or on a surface that will not scratch it.
Most Seiko watch backs either snap on or are held on with screws. If the backing has screws, use a small screwdriver to loosen the screws. For watch backs that snap on, find the elevated lip near the watch band. Place the tip of a flat head screwdriver under the lip and pry watch back open.
Once the watch back is lifted, take out the battery by tipping the watch sideways until it falls out.
Place the new battery into the watch and gently press it into place until you are sure the battery is snug.
Return the watch's back and either screw it back in or firmly press until it snaps into place.
In order to find out what type of battery you need for your Seiko watch, look for the battery number on the battery's top side. Once you know this number, go to a watch repair shop and ask for that same type of battery.
If your Seiko watch has little notches all along the edges of the back, it has a backing that requires a special press to remove it. There are ways to unscrew this back at home, but it is extremely difficult and you may hurt yourself in the process. These types of watch backs may need the attention of a watch repair store.
