Why does Rolex use jewels in their watches?
Rolex uses jewels, primarily synthetic rubies, in their movements to reduce friction and wear between moving parts. These jewels act as bearings, providing a smooth surface for gears and other components to rotate or pivot. Without jewels, the metal-on-metal contact would quickly lead to significant friction, heat, and ultimately, the breakdown of the movement.
The use of jewels greatly extends the lifespan and improves the accuracy of Rolex watches. The reduced friction allows the movement to operate more efficiently, requiring less energy to maintain time. This results in more consistent performance and less frequent servicing, contributing to the legendary reliability that Rolex watches are known for.
How many jewels are typically found in a modern Rolex watch?
The number of jewels in a modern Rolex watch movement typically ranges from 31 to 41, depending on the specific caliber and its functions.
