When evaluating pocket watches, it is important to assess the quality of the movement as well as the condition of the dial and case. Jewels are an important watch component that help to reduce friction at movement pressure points and ensure the watch operates correctly over a long period of time.
Pocket watch jewels come in several forms, including round shaped hole and cap jewels, angled pallet jewels, and pin style impulse jewels. Jewels can be set with friction, where they are pressed into a tight hole that keeps them secured. Watches with friction set jewels are typically less expensive and lower quality. Another method to set jewels includes the use of small screws which attach to the movement plate. Screw set jewels can be flush with the plate or a raised style where the setting’s rim is slightly elevated. Watches with screw set jewels are often higher quality pieces.

With Smithsonian magazine calling the pocket watch the “first wearable tech game changer” in the world, the importance of the pocket watch to human civilization is readily apparent. The precise origins of the pocket watch may be lost in history, although medieval people were familiar with mechanical clockworks. Renaissance-era portraits show men holding watches of various types suspended from ribbons or chains, in an era where simple mainspring technology flourished.
Some authorities believe the pocket watch was invented by Italian makers in the 15th century. Many others point to Peter Henlein, the Nuremberg watchmaker and creator of a single-hand device early in the 16th century. In any case, both men and women were using portable watches in the 1500s. The earliest models were egg-shaped and bulky, but they were soon replaced by flatter case shapes.
King Charles II of England is said to have popularized the securing of pocket watches by chains. When he introduced the wearing of waistcoats in the late 17th century, he provided men with a fashionable way to carry their pocket watches.
