Out of the many little things you’ve always wondered about, one of them probably has to do with the small fifth pocket on your jeans. By now, you might have given up on trying to use it since it’s too darn small to fit anything you actually need. But why is it there in the first place? Well, today, it doesn’t really serve a purpose, but it used to in the late 1800s.
The small pocket is actually called a watch pocket because it was originally intended as a safe place for men to store their pocket watches. It dates back to Levi’s first ever pair of jeans, which hit the market in 1879. (Check out more things you never knew actually had names.)

“The first blue jeans had four pockets—only one in back and, in the front, two plus the small, watch pocket,” the blog stated. (Discover more hidden meanings of everyday objects.)
