So, yes, historically watch jewels are, indeed, made of precious stones! However, as time and technology allowed, a few innovations managed to cut down a lot of costs for movement manufacturers. Before that, manufacturers employed the help of quartz, glass, or garnet in the process. Each bearing makes the gears turn smoothly.īack in the day, watch jewels are made of actual precious gems such as a ruby. Because these bearings are made of precious stones, their smoothness aids in keeping friction from getting in the way of energy production of a movement. Most of the high-end, self-winding, and hand-wound watches in the market, then and now, have bearings made out of jewels. These parts help the movement move, rotate, and, at the end of the process, help the hands of the watch tick. A movement is a complicated assemblage of various little parts such as gears and springs. The function of the watch jewels is to aid this process. Instead, they use a spring-wound mechanism to run. We all know mechanical watches do not require batteries to function. They’re described as tiny synthetic ruby or sapphire pieces set into the holes of the movement. Watch jewels, jewel bearings, or simply jewels can be found within a watch’s movement. But what purpose do they really serve? Do these parts necessarily change the value of a timepiece? Read on to find out. Either way, watch jewels are indispensable, especially for mechanical movements. However, there are some who simply don’t pay attention to this detail. In fact, serious watch collectors check how many jewels a movement has before making a purchase. Watch jewels are vital parts of a mechanical timepiece.
