The role of rubies in watch mechanics

Rubies in watches are not merely aesthetic elements: they are used to reduce friction between gears and pivots, ensuring long-term accuracy and reliability. Their strategic placement within the movement minimizes wear and optimizes the smooth continuity of timekeeping.

Did you know? Modern synthetic rubies have the same mechanical properties as natural ones, but without imperfections, resulting in a more stable and precise movement.

How rubies ensure precision

Each ruby is positioned at critical points such as the balance wheel, escapement and main gear train. This guarantees:

• Reduced friction and vibrations
• Improved timekeeping stability
• Greater durability and long-term resistance

Technical note: the number of rubies varies depending on the complexity of the calibre and its chronometric functions.

From the workshop to perfection

In our workshop, each ruby is positioned with micrometric precision to ensure optimal interaction between components. This meticulous attention to detail reduces timing deviations and guarantees maximum reliability of the watch.

Expert tip: selective lubrication on ruby jewels further increases movement efficiency.

Rubies in the history of watchmaking

The use of rubies in watch movements dates back to the 19th century. At the time, watchmakers adopted them to improve accuracy and reduce maintenance. Today, this tradition has evolved thanks to modern techniques, but the principle remains unchanged: the ruby is at the heart of precision.

Fun fact: some antique pocket watches with ruby jewels still maintain remarkable accuracy after more than 100 years.
