The vast majority of watches which run on batteries, take one of the 300-series of watch batteries. All of these are button cells, and they all use Silver Oxide technology. They all have a voltage of 1.55V, and last for a long time, both in use and while stored.
Compared to other battery technologies, Silver Oxide technology features one of the greatest capacities to store electricity for a certain volume. This obviously matters in a watch, where the battery is often not easily accessible, and there's no space to waste. Silver Oxide technology also provides a near constant voltage over the entire life of the battery. This is essential to ensure watch accuracy, and could not be attained easily with alkaline battery technology.
Unfortunately, battery manufacturers have never agreed one standard convention for battery labels. Fortunately, our database has cross-referenced most of these labels, so you can find the right battery for your watch by using the label on your old battery in our battery search. Alternatively, you can look up the battery code in the watch battery cross reference table.
