The purpose of these jewels is to act as bearings to various components in the watch specifically the parts that would normally wear down easily such as the escape lever and the impulse jewel.

Before the ’70s, when battery-powered (quartz) watches were introduced, all watches were mechanical and used about five to seven jewels in the watch’s caliber.

As everyone knows there are so many wearing parts available in the mechanical wristwatches. Gear wheels, shafts, and bearings and to obtain high quality and high accuracy for long lifetime, designers embedded high strength jewels with having high wearing resistance, non-degradable with time, and lightweight.
