Never stop asking why

In 2013, MAURON MUSY was born from a simple question: why accept existing limits when mechanics allow us to imagine differently?

At the origin of the brand is the encounter between Eric Mauron and Christophe Musy, two complementary backgrounds united by the same vision: exploring new possibilities in mechanical watchmaking. Their approach, shaped by precision, materials, and innovation, led them to create differently, seeking harmony between function, technique, and design.

This philosophy gave birth to the nO-Ring® technology, a completely new approach to mechanical water resistance, and led to the brand’s presentation at Baselworld in 2015. In 2016, the first collection was introduced. This was followed by the development of exclusive movements and the creation of timepieces entirely designed and crafted in Switzerland.

Today, the atelier continues to operate with the same mindset. Engineering and instinct. Precision and creativity. Observation, experimentation, and coherence. Each creation is the result of a constant pursuit of balance between technical mastery and the freedom to imagine differently.

Keep exploring. Keep creating. Keep asking why.


In the Broye Valley, far from the major watchmaking hubs, our Manufacture is housed in a former farmhouse, in the heart of a small country village.

Nothing of an industrial building. A house that became a Manufacture. Workshops. Around ten people. 300 timepieces per year. It is here that our watchmakers assemble our movements from A to Z. Here that we produce our components. Here that we develop our own calibres. Here that we design, test and adjust.

It is also here that we welcome our collectors from all over the world. Everything comes together under one roof. Design, engineering, production, exchanges. A small team. One single place. Watchmaking entirely conceived and crafted on site.

The nO Ring® technology was born from a simple question

if a watch is meant to last for generations, why make it dependent on a perishable component?

Coming from an industrial background, accustomed to solving mechanical problems through logic and precision, Christophe Musy approached watchmaking as an equation to be solved, not a tradition to be repeated. How can one accept, in an object designed to endure, a plastic gasket that must be replaced every three years?

The answer was mechanical. He filed a patent. Removed the rubber gaskets. And created the only water resistant watch without gaskets. Water resistance relies on geometry, pressure and extreme precision, down to 0.01 micron, achieved through diamond paste finishing in our workshop. The technology dictated its form: a four part case, directly derived from this patented architecture. This design, born from function, became the signature of the Maison and the foundation of its success. The result: a more durable watch. More coherent. More logical.

For us, Swiss Crafted is a conviction. We know the people behind every component. The workshops. The gestures. The standards. Swiss Made sets a minimum. We chose to aim for the maximum. Our timepieces are entirely manufactured in Switzerland, with partners located within a 60 kilometer radius of our Manufacture.

We work locally because craftsmanship can only be preserved if it is practiced. Because the finest expertise is here. Because giving up this coherence would have meant compromise. We were not prepared to make it. When everything is close, everything is under control. And every detail reflects it.
