What are jewels in watches? Jewels, also known as watch jewels, play a crucial role in the precision and longevity of mechanical watches. These tiny, high-quality synthetic or natural stones are meticulously set into the movements of watches to reduce friction and ensure smooth operation. In this article, we will explore the significance of jewels in watches, their types, and how they contribute to the overall performance of a timepiece.
The use of jewels in watches dates back to the 18th century when English watchmaker George Graham introduced the concept of using jewels to reduce friction in watch movements. Initially, natural diamonds were used, but they were rare and expensive. Over time, synthetic jewels and other materials have been developed to provide the same benefits at a more affordable cost.
Types of Watch Jewels
There are several types of jewels used in watches, each serving a specific purpose. The most common types include:
1. Ruby Jewels: Ruby jewels are the most popular choice for watch movements. They are known for their hardness and durability, making them ideal for the escapement wheel and lever, which are the components that control the watch’s timekeeping.
2. Saphire Jewels: Saphire jewels are used for the balance staff and pinions, as they offer excellent hardness and resistance to wear. They are also used in the watch’s crystal, providing a clear and scratch-resistant cover.
3. Netherite Jewels: Netherite jewels are a type of synthetic material that is highly resistant to wear and corrosion. They are often used in the watch’s escapement wheel and lever, providing long-lasting performance.
4. Diamond Jewels: Diamond jewels are the most durable and offer the highest level of precision. They are typically used in the watch’s escapement wheel and lever, but their high cost makes them less common in everyday watches.
Benefits of Watch Jewels
The use of jewels in watches offers several benefits, including:
1. Reduced Friction: Jewels are much harder than metals used in watch movements, which means they reduce friction between moving parts. This results in smoother operation and increased longevity of the watch.
2. Precision: The use of jewels ensures that the watch’s movement remains precise over time. This is especially important for mechanical watches, which rely on the intricate balance of their components to keep accurate time.
3. Durability: Jewels are highly resistant to wear and corrosion, which means they can withstand the harsh conditions inside a watch movement without losing their shape or size.
4. Aesthetics: The presence of jewels in a watch movement adds to its overall beauty and craftsmanship. High-end watches often feature multiple jewels, showcasing the intricate details of their construction.
Conclusion
In conclusion, jewels in watches are essential components that contribute to the precision, durability, and beauty of mechanical timepieces. From the early days of watchmaking to the modern era, the use of jewels has been a testament to the artistry and innovation of watchmakers. As we continue to appreciate the intricacies of these exquisite timepieces, the importance of jewels in watches will remain a vital aspect of their craftsmanship.
