Have you ever gazed at your watch and wondered what lies beneath its elegant face? Let's dive into the world of watch jewels, the unsung heroes of timekeeping. These tiny yet mighty components are far more than just decorative elements; they play a crucial role in the functionality and longevity of a watch. In this article, we'll explore the functional role of watch jewels, their history, and their impact on the precision of your timepiece.
The Functional Role of Watch Jewels
Jewels in watches, contrary to what one might assume, aren't there for ornamental purposes. They serve a functional role, primarily to reduce friction in the movement. These jewels, typically synthetic rubies or sapphires, are strategically placed in parts of the watch movement. Their hard surface, rating a "9" on the Mohs hardness scale, ensures that the metal components of the watch can move freely without excessive wear. Watch jewels serve as:
- Functionality Over Aesthetics: Despite their name, watch jewels are not for decoration. They serve a crucial functional role in the movement of a watch.
- Friction Reduction: The jewels provide hard, smooth surfaces for the pivots of the watch's gears, reducing wear and tear. This is vital because friction between metal parts can cause variations in timekeeping and lead to premature wear.
- Material: While natural rubies were initially used, modern watch jewels are typically made from synthetic sapphire or ruby. These synthetic stones have the same properties as their natural counterparts but are more consistent in quality and less expensive to produce.
- Placement: Jewels are strategically placed in parts of the watch movement that experience the most wear, such as the balance wheel pivots.
- Jewel Count: Watches often specify their "jewel count," which indicates the number of jewels used in the movement. A higher jewel count can sometimes indicate a more complex and precise movement, but this isn't a strict rule. A typical fully jeweled time-only watch has 17 jewels, but more complicated movements can have many more.
- Not for Ornamentation: It's essential to differentiate between functional watch jewels in the movement and decorative gemstones that might be set into a watch's dial, bezel, or case for aesthetic purposes.
A Glimpse into the History of Watch Jewels
The use of jewels in watchmaking isn't a recent phenomenon. Their history traces back to the early 1700s when Swiss inventor Nicolas Fatio d Duilier, along with brothers Peter and Jacob Debaufre, introduced jewel bearings. Initially, these jewels were made of diamonds and corundum (rubies or sapphires).
Over time, as the benefits of reduced friction and increased accuracy became evident, the use of jewels in watches became widespread. Today, synthetic versions of these gemstones are used, making high-quality watchmaking more accessible.
Deciphering the Jewel Count
A common term you might come across when delving into watch specifications is the 'jewel count'. This refers to the number of jewels incorporated into the watch movement. A fully jeweled watch typically has a count of 17 jewels, but some high-end models can have up to 21 jewels or more. The jewel count can be an indicator of the watch's quality and precision.

Understanding the Different Types of Watch Jewels
Watch jewels come in various types based on their specific functions and placements within the movement. Here are the main types of watch jewels:
- Hole Jewels: These are the most common type of jewel and are used as bearings for the pivots of moving parts like gears. They are typically cylindrical with a hole in the center.
- Cap Jewels (or Endstones): These are flat jewels placed on top of hole jewels, especially in high-friction areas like the balance wheel pivots. They help distribute the load and reduce wear.
- Pallet Jewels: Found in the pallet fork of the escapement mechanism, these jewels interact with the escape wheel to regulate the release of energy from the mainspring.
- Roller Jewel (or Impulse Jewel): This jewel is attached to the balance wheel's roller table. It interacts with the pallet fork to transmit impulses between the escapement and the balance wheel.
- Jewel Bearings: These are hole jewels specifically used for the wheel train. They reduce friction between the moving wheels and the stationary parts of the watch.
- Shock-Absorbing Jewels: Some watches, especially sports watches, use jewels in shock-absorbing settings (like Incabloc or Kif) to protect the movement from impacts. These systems usually have a spring-loaded setting that allows the jewel to move slightly upon impact and then return to its original position.
- Pallet Fork Horn Jewels: These are less common and are used in some high-end or vintage watches. They reduce friction where the pallet fork interacts with the balance wheel.
