A Deep Dive into the Role of Jewels in Watches

Hello, horology enthusiasts and curious minds alike! Today, we venture on a thrilling journey to understand a fascinating component of watchmaking that may seem decorative but is critical to the mechanism of our beloved wrist companions - the jewels.







When one mentions jewels, it might conjure up images of sparkling gemstones adorning jewelry. However, in the realm of horology, jewels serve a far more practical purpose. Contrary to what you might think, they're not there for decoration but perform a crucial function in the intricate mechanics of a watch. So, let's dive in and discover the role of these minute yet mighty elements in our timepieces.



Jewels in watches are typically made from synthetic ruby or sapphire, thanks to their hardness and resistance to wear over time. In a nutshell, these jewels serve as bearings for the many gears and moving parts in the movement, reducing friction, enhancing precision, and increasing the lifespan of the watch.



Their journey dates back to the early days of mechanical watchmaking when metal pivots turning in metal holes were a standard. However, this caused a considerable amount of friction, leading to wear and tear, and necessitated frequent winding. Furthermore, the lack of lubrication made timekeeping less precise, a challenge that watchmakers of the day sought to address.



The turning point came in the 18th century when Nicolas Fatio de Duillier, a Swiss mathematician and watchmaker, together with Pierre and Jacob Debaufre, received a patent for the use of jewels in watches. Their pioneering work led to the use of drilled, real ruby and sapphire jewels as bearings to reduce friction. This marked the dawn of a new era in horology, as the addition of jewels significantly improved timekeeping accuracy and the overall longevity of the watch.



However, the laborious process of creating these small jewels and integrating them into watches made timepieces incredibly expensive. As such, jewels became a status symbol, with more jewels indicating a higher-quality, more prestigious watch.







This changed in the 20th century with the advent of synthetic rubies. Auguste Verneuil, a French chemist, revolutionized the industry with his flame fusion process to create synthetic sapphires and rubies. This breakthrough reduced the cost of jewels and made them more accessible, leading to their widespread use in watchmaking.



In the 19th and early 20th century, watchmakers began increasing the jewel count in their watches, a trend that led to an intriguing phenomenon known as 'jewel inflation'. While a typical mechanical watch only requires around 17 jewels to function effectively, manufacturers started to add more jewels beyond the necessary amount. This was driven partly by marketing tactics, as consumers equated the number of jewels to the quality of the watch, and partly by the desire for innovation and experimentation among watchmakers.



Fast-forward to the mid-20th century, when another significant development occurred: the introduction of the Incabloc shock protection system. This Swiss invention used jewels to create a flexible setting for the balance staff, which helped protect the watch's most sensitive part against shocks. This further cemented the role of jewels in ensuring a watch's durability and reliability.



Today, jewels are a ubiquitous part of mechanical watches, from the most basic models to the high-end complications. They serve an essential purpose in the quest for timekeeping accuracy, mechanical efficiency, and longevity of a watch.







As we continue this journey in our next segment, we'll delve deeper into how these jewels function in various parts of a watch movement and how they contribute to the art and science of watchmaking. We'll also explore some iconic timepieces known for their generous use of jewels. Stay tuned for a closer look at these glittering marvels that help your favorite timepiece tick with grace and precision!



Stepping back into our sparkling exploration of jewels in timepieces, let's zoom in on four stunning examples of horological artistry, where jewels play more than just a supporting role. From everyday watches to extravagant creations, these timepieces exemplify the crucial role jewels play in the art of watchmaking.



The Rolex Calibre 3135, found in many of the brand's iconic models like the Submariner and the Datejust, is a paragon of Rolex's precision and reliability. With 31 jewels incorporated into its movement, this calibre showcases the standard use of jewels in contemporary watchmaking.







The jewels in the Calibre 3135 minimize friction at key points, increasing the movement's efficiency and lifespan. The use of synthetic rubies ensures minimal wear, even after years of continuous operation. This longevity and precision, hallmarks of Rolex timepieces, owe much to these tiny, yet crucial, components.



Moving on, we find a higher jewel count in the Omega Co-Axial Calibre 8500. With a substantial 39 jewels, this movement is a testament to Omega's commitment to accuracy and durability. The jewels, primarily situated in the gear train and the escapement, significantly reduce friction, ensuring smooth and long-lasting performance.







Introduced in 2007, the Calibre 8500 was Omega's first in-house movement with the Co-Axial escapement, a George Daniels' invention that further reduces friction within the movement. The jewels in the Calibre 8500 not only enhance its functioning but also showcase Omega's innovative spirit and dedication to excellence.



Now let's step into the world of haute horology with the Jaeger-LeCoultre Calibre 101. Created in 1929, this mechanical movement, renowned as the world's smallest, boasts 98 tiny parts, including 21 jewels. The extensive use of jewels in this miniaturized marvel underscores their importance in ensuring accurate timekeeping in even the most delicate of mechanisms.







The Calibre 101, favored by Queen Elizabeth II and numerous Hollywood stars, is a symbol of Jaeger-LeCoultre's ingenuity and craftsmanship. The extensive use of jewels in this tiny powerhouse ensures its longevity and precision, embodying the timeless allure of Jaeger-LeCoultre creations.



Finally, let's go back in time to the extravagant Breguet Marie-Antoinette Grande Complication pocket watch. Commissioned by an admirer of Queen Marie Antoinette and completed 34 years after her death, this timepiece features an impressive 23 complications and a staggering 823 parts, including many jewels.







Not only do the jewels ensure the smooth functioning of its numerous complications, but they also add to the timepiece's luxurious aesthetics. This pocket watch, with its intricately jeweled movement, stands as a testament to Breguet's historical craftsmanship and the pivotal role of jewels in complex timepieces.



From our everyday wristwatches to the epitomes of horological extravagance, jewels play an integral role in the functioning, longevity, and precision of our cherished timepieces. Their journey, from natural rubies to synthetic sapphires, from status symbols to standard components, mirrors the evolution of watchmaking itself. As we marvel at the intricate dance of gears and wheels every time we glance at our watches, let's not forget these tiny glittering heroes that quietly ensure our timepieces keep ticking accurately and smoothly.



Whether you're a seasoned horology enthusiast or a curious beginner, the next time you look at your watch, take a moment to appreciate the complex symphony of parts working together to track time. And remember, at the heart of it all are the jewels, the unsung heroes of horology, guiding the rhythms of our days and nights. From the humble wristwatch to the grandest of complications, they're a shining reminder of the marvels of watchmaking, blending artistry and engineering in perfect harmony.
