For example, a chronograph will have a higher energy consumption than a watch that only indicates hours, minutes and seconds.
Do brand name batteries last longer? Our exclusive test results gathered by the Worcester Polytechnic Institute show that in terms of power over time, there’s no discernible difference between expensive, name-brand batteries and cheaper generic ones.
What does SW mean on a battery?
