Are all watch batteries the same?
All watch batteries are not the same. We have 2 basic types, 1.55 volt silver oxide batteries and 3.0 volt lithium batteries. We stock about 55 different sizes of these 2 types of batteries. A watch movement takes a specific size and type of battery and they cannot be interchanged. Most of the time we can only tell what battery your watch needs by taking off the back of the watch.
