The skeletonised calibres manufactured by Roger Dubuis in Geneva are the essence of the expressive singularity of the Excalibur collection. In accordance with one of the most prestigious certifications in Haute Horlogerie, the Poinçon de Genève, Excalibur watches are designed as contemporary works of art. Since each and every component is hand-finished, these watches are true marvels. These timepieces, the result of work by highly skilled watchmakers, allow direct contemplation of the creative mechanics that bring these pieces to life like never before.
