350 Years of Precision: The Spiral’s Transformation in Horology

In the intricate world of horology, the spiral is more than just a component.

It’s the heart of a mechanical watch, and a symbol of precision and portability in timekeeping. A recent exhibition at the Musée international d’horlogerie in La Chaux-de-Fonds, Switzerland, celebrates 350 years of the spiral’s journey through “L’innovation en mouvement. 350 ans du spiral”.

The Birth of the Spiral

In 1675, the first published sketch of the spiral regulating spring by the renowned Dutch scientist Christiaan Huygens appeared in Journal des Sçavans.

This tiny, slender spring similar to a human hair was a critical advancement. It allowed portable timekeepers to meet unprecedented precision, revolutionizing navigation at sea.

“It’s a gradual change rather than a radical shift,” says Régis Huguenin, the conservator at the MIH. “Oscillators have existed in timepieces since ancient times. The challenge was to make them portable. It’s the spiral that plays this role in a watch, a portable pendulum.”

The Swiss Evolution

In the Swiss Jura Mountains surrounded by Neuchâtel, the research fever gripped the nation after the introduction of the spiral.

One of the orchestrators was Charles Édouard Guillaume, born in Fleurier in 1861. The Nobel Prize laureate in Physics invented metals like Invar and Élinvar.

These alloys were resistant to temperature and magnetism fluctuations, contributing to a precise, reliable spiral performance across diverse conditions.

The story continues into the 21st century. There’s a constant push for improvement in mechanical watch accuracy, notably through the introduction of silicon as its new material.

A Journey Through Time

The MIH’s “L’innovation en mouvement. 350 ans du spiral” exhibition takes visitors through the historical innovations in spiral design.

On display are items ranging from the 17th-century spiral regulating springs to the latest advancements in 21st-century horology.

Visitors can delve deeper into broader horology facets, including industrialization, women’s roles in watchmaking, and the quest for the perfect timekeeping mechanism.

Discovering the Spiral Legacy

Currently, the “L’innovation en mouvement. 350 ans du spiral” exposition, presented in collaboration with the Dutch foundation Stichting Haegsche Tijd, offers timekeeping enthusiasts a chance to experience horological history.

The show runs until June 22nd at the Musée international d’horlogerie in La Chaux-de-Fonds, inviting seekers of precision engineering to witness firsthand how the spiral transformed timekeeping.
