If you’ve ever wondered why jeans have those tiny pockets, you’re about to find out.
While many people use them to store loose change or small items, their original purpose might surprise you.
These small pockets, typically sewn inside the larger front pocket, have sparked plenty of speculation over the years.
Social media users have shared their own theories, with one Twitter user joking, “To hide money so you’ll forget about it and find it when you’re broke.”

Another person shared, “Mom used to say, ‘A quarter for the phone.’”
But the history of these tiny pockets goes back much further, all the way to the 1870s, when the first pair of jeans was created in 1873. Surprisingly, they were designed for an item that’s now rarely used in modern society.
What Were the Tiny Pockets in Jeans Originally Designed For?
These small pockets were originally made to hold pocket watches, which were small timepieces encased in metal and commonly used at the time. While wristwatches did exist back then, they didn’t become widespread until the 20th century, making pocket watches the go-to for telling time.
Historian Tracey Panek, who works for Levi Strauss & Co., the original makers of jeans, provided more insight into their purpose. Speaking to Insider, she explained:
“The oldest pair of waist overalls in the Levi Strauss & Co. Archives (from 1879) include the watch pocket. Our 19th-century overalls had a single back pocket on the right side of the pant beneath the leather patch.”
At the time, “waist overalls” was the original name for blue jeans, first created by Levi Strauss & Co. in 1873.
Why Do Jeans Still Have the Tiny Pockets?
Although pocket watches have faded from use, jeans still feature these small pockets today, especially in Levi’s designs.
Panek revealed an interesting historical detail: “During WWII, the two corner rivets were removed as a way to conserve metal for the war effort.”
After the war, the rivets were reintroduced, reinforcing the pocket’s durability. The iconic Arcuate stitching, a signature Levi’s design, was also added using a single-needle sewing machine.
So while most people no longer carry pocket watches, this tiny pocket remains a nostalgic and functional part of jean design, proving that some features stand the test of time.

“The watch pocket was an original feature of our blue jeans, just like the rivets on our pockets, button fly, arched back pocket stitching, and leather patch,” Panek explained.
“To preserve the integrity of the early design, Levi Strauss & Co. continues to include the watch pocket.”
On Levi’s website, she further elaborated:
“This cinch-free blue jean, with the uniform look of the Arcuate, a contrast to previous years when the single-needle application made each design unique, was the blueprint for the future of denim. You can still see this design in our 501 jeans more than 70 years later.
“Levi’s emerged from World War II looking fresh, modern, and uniformly manufactured.
“With distribution expanding across the globe, it was well on its way to becoming the iconic, worldwide garment it is today.”
