Les Ateliers Gilbert Petit-Jean SA, BBHG SA, and Béguelin Sàrl operate as independent sister companies grouped together within a single, integrated alliance.
They operate out of a centralized, modernized production facility located in Les Brenets, Switzerland. This geographic proximity allows them to serve as a single, streamlined partner for luxury watch brands.
By bringing their manufacturing capabilities together, they verticalize the watchmaking process:
Gilbert Petit-Jean SA: Specializes in watch finishing, decoration (such as hand-angling and perlage), stone-setting, movement pre-assembly/assembly, and casing.
BBHG SA: Focuses on exterior watch components (habillage horloger). They machine, industrialize, and develop high-precision watch cases, bracelets, buckles, and clasps out of precious and technical metals.
Béguelin Sàrl: Completes the trio by providing specialized micro-machining, precision tooling, and components.
