Many people ask the question, "How long should my watch battery last?" This time varies, from watch to watch, but as a general rule, when a watch is new, it should last 2-3 years, but as they get older, that gets closer to 1 year.
The reason for that is because, just like anything else, a new watch will work incredibly well, and as time goes on, it takes more "juice" for the watch to run. This results in a shorter battery life as time goes on.
Quartz watches (the majority of watches today) typically use either a 1.55V silver oxide battery, or a 3V lithium battery. You don't really need to know that--the only thing to remember is that one is bigger than the other, and the bigger one is usually used in a digital watch.
So, the bottom line is: You'll probably have to get your watch battery replaced every 1-2 years.
