The Significance of Jewels in Pocket Watches- A Glimpse into Their Role and Importance
What does jewels mean in pocket watches? This term refers to the small, precious stones that are used to reduce friction in the movement of a pocket watch. Historically, jewels have been a crucial component in the design of these timepieces, as they ensure smooth and precise operation. In this article, we will explore the significance of jewels in pocket watches, their types, and how they contribute to the overall performance and longevity of these exquisite timepieces.
The use of jewels in pocket watches dates back to the 18th century, when watchmakers began incorporating them into the movement to enhance the watch’s performance. Initially, only a few jewels were used, but over time, the number increased as watchmakers discovered the benefits of using more jewels. Today, the average pocket watch may contain anywhere from 17 to 25 jewels, depending on the watch’s complexity and design.
The primary purpose of jewels in pocket watches is to reduce friction between the gears and other moving parts. This is achieved by using the hard, smooth surfaces of the jewels to act as bearings, which allow the gears to rotate more smoothly and accurately. Without jewels, the friction between the gears would cause the watch to slow down or stop, leading to inaccurate timekeeping.
There are several types of jewels used in pocket watches, each with its own unique properties and benefits:
1. Ruby jewels: These are the most common type of jewels used in pocket watches. They are made from the mineral corundum, which is the same material that forms sapphires and rubies. Ruby jewels are known for their hardness and durability, making them ideal for use in watches.
2. Steel jewels: Steel jewels are used in high-quality pocket watches and are known for their resistance to wear and tear. They are often used in the escapement and balance staff of the watch movement.
3. Synthetic jewels: These jewels are man-made and offer a cost-effective alternative to natural jewels. They are used in watches that are designed for everyday wear and do not require the same level of precision as high-end timepieces.
The number of jewels used in a pocket watch can also indicate its quality. A watch with more jewels is generally considered to be of higher quality, as it suggests that the watchmaker has taken the time to incorporate additional components that will ensure smooth and precise operation. However, it is important to note that the number of jewels alone does not determine the overall quality of a watch. Other factors, such as the materials used, craftsmanship, and the complexity of the movement, also play a significant role.
In conclusion, jewels are an essential component of pocket watches, providing the necessary friction reduction to ensure accurate timekeeping. The types of jewels used, as well as the number of jewels, can provide valuable insights into the quality and craftsmanship of a pocket watch. As timepieces that have stood the test of time, pocket watches with jewels continue to be cherished by collectors and enthusiasts alike.
