The first pocket watches originated in the 16th century. However, they were pretty different from the pocket watches we are familiar with today. The earliest pocket watches were large and bulky, like portable clocks carried in their pockets. They were typically made in the shape of a sphere or cylinder and were powered by weights or springs.

Peter Henlein, a German locksmith and watchmaker, is often credited with inventing the pocket watch around 1504. His early designs were portable timepieces worn on a chain around the neck or carried in a pocket.

These early pocket watches had only an hour hand and didn't have a minute hand or a protective glass cover over the dial. The time was usually set by observing the sun's position or using other reference timepieces.

Over time, pocket watches became more refined and compact. They evolved into minute hands, protective covers or lids, and more intricate designs. The introduction of the balance spring in the 17th century significantly improved their accuracy and made them more practical.

By the 18th and 19th centuries, pocket watches had become highly valued and fashionable. They were often crafted with intricate engravings, made of precious metals, and adorned with gemstones. Pocket watches remained the primary timekeeping devices until the late 19th century, when wristwatches started gaining popularity.

Today, pocket watches are considered more of a vintage or luxury item, often sought after by collectors or individuals who appreciate their historical and aesthetic value. They are less commonly used for everyday timekeeping purposes, with wristwatches and smartphones being more prevalent.
