Blancpain Grande Sonnerie: Inside the Le Brassus Manufacture

24 November 2025 · The Horology Club

We were invited to the Vallée de Joux to discover Blancpain, a brand we have long admired but never fully understood.

Join us as we explore the manufacture in Le Brassus, meet the craftspeople behind the watches and get up close with the Grande Sonnerie, the culmination of everything Blancpain knows about haute horlogerie.

In this episode

  • A tour of the Blancpain manufacture in Le Brassus
  • Meeting the craftspeople behind the watches
  • The Grande Sonnerie, Blancpain's most complicated watch

Tell us in the YouTube comments: what impressed you most about the Grande Sonnerie, and which complications would you prioritise in your dream watch?
