The Sparkling Heart of Swiss Precision

Rubies have been integral to the watchmaking industry for centuries, providing both functional and aesthetic benefits that enhance the precision and longevity of timepieces. Here’s an expanded analysis of their use and impact from various perspectives.

Historical Context and Development

The integration of rubies in watchmaking began in the 18th century to reduce friction and wear in the mechanisms. Initially, natural rubies were used, but the advent of synthetic rubies in the early 20th century, through the Verneuil process, revolutionized the industry. This process allowed for the mass production of high-quality synthetic rubies, making them accessible and cost-effective compared to natural rubies​ (Luca Watch)​​ (Comadur)​.

Functional Role of Rubies

Rubies are primarily used as bearings in watch movements. They reduce friction at pivotal points where metal components interact, such as in the gear trains and escapement mechanisms. This reduction in friction minimizes wear and tear, ensuring the watch maintains its accuracy over time. Additionally, rubies are placed in the balance wheel pivots, enhancing the timepiece’s precision by supporting consistent oscillations​ (CHARLIE)​​ (Luca Watch)​.

Economic Impact on the Swiss Watchmaking Industry

The use of rubies has had a significant economic impact on the Swiss watchmaking industry. By improving the durability and reliability of watches, rubies have helped maintain the high standards associated with Swiss watchmaking, contributing to its global reputation. The Swiss watch industry, accounting for around 1.5% of the country’s GDP, heavily relies on such innovations to sustain its competitive edge in the luxury market​ (SWI swissinfo)​​ (Switzerland Tourism)​.

Technological Advancements

Technological advancements have further refined the use of rubies in watches. The development of synthetic rubies has allowed for consistent quality and availability, crucial for large-scale production. Moreover, the integration of anti-shock systems, where rubies are mounted on springs to absorb shocks, has enhanced the resilience of watches. These systems, such as the Incabloc and Kif, protect the delicate components of the watch from damage due to impacts​ (Comadur)​​ (Luca Watch)​.

Challenges and Future Prospects

While rubies offer numerous benefits, their precise placement in watch mechanisms remains a challenge, requiring meticulous craftsmanship. Advances in manufacturing technologies continue to improve the efficiency and effectiveness of using rubies. Looking ahead, synthetic rubies are expected to remain a staple in watchmaking, with ongoing innovations likely enhancing their application, leading to even more accurate and durable timepieces​ (CHARLIE)​.

Symbolic and Aesthetic Value

Beyond their functional benefits, rubies add significant aesthetic value to watches. The vibrant red hue of rubies is associated with luxury and craftsmanship, enhancing the visual appeal of high-end timepieces. This dual role of functional and aesthetic enhancement underscores the symbolic value of rubies in horology, representing both precision engineering and exquisite design​ (CHARLIE)​​ (Comadur)​.


Rubies play a critical role in Swiss watchmaking, blending tradition with innovation. By reducing friction and enhancing durability, rubies help maintain the accuracy and longevity of timepieces. As technology advances, these precious gemstones will continue to be integral to high-quality watchmaking, reflecting the art and science of horology. The ongoing development in synthetic ruby production and application will further solidify their role in the future of watchmaking.
