Lavoisier Composites x Clément Entretemps: The truth about carbon

Carbon in watchmaking is everywhere, but do we really understand it? Between marketing and technical reality, the line is blurred. To debunk common misconceptions, Clément Entretemps immersed himself in our workshops near Lyon. On the agenda: discussions with our experts and discovery of our exceptional materials. A technical immersion that you can now find in video form on YouTube.

Lavoisier Composites x Clément Entretemps: The truth about carbon
Annaëlle Cadet

Materials science meets watchmaking

Why is carbon so highly prized?
Is it simply a matter of aesthetics?

 
To answer these questions, Clément Entretemps came to dissect the subject of carbon fiber materials in its entirety. To understand what is really happening behind the commercial names, he went to our workshops in La Mulatière, where the material is transformed.

Through his discussions with Esteban Villalon, Bastien Durif and Nicolas Neuville, Clément was able to compare theory with practice. This immersive experience reveals what defines the DNA of Lavoisier Composites: total mastery, from the reprocessing of high-performance fibres right through to precision machining.

Débunker pour mieux comprendre 

 Far from marketing hype, this unfiltered report challenges common misconceptions. Clément sought the expertise of our teams to clarify some key points:

  • The truth about "forged carbon": A return to the roots with Nicolas Neuville, who took part in the sport’s first historic series.
  • The demands of machining: Why we choose to machine our materials right through to the core to reveal a unique aesthetic and scratch resistance far superior to that of injection-moulded plastics
  • The quest for finesse: A demonstration with Bastien Durif of our ability to produce carbon fiber components with a thickness of 0.3 mm. This technical capability opens new design perspectives for dials and decorative movement parts, as illustrated by our collaborations with high-end watchmaking houses such as Ulysse Nardin.

Machining fine part (0.3 mm)

This profile exemplifies our unique expertise: extreme lightness combined with structural strength, making it ideal for the most demanding applications.


Whether you’re curious to find out how carbon is used in watchmaking or how we work with these composites to make them unique, this video is the ultimate guide to our expertise.
