The atelier behind other brands

Bernhard Zwinz established L’Atelier de Joux in 2004 as an independent horological development and execution workshop. Zwinz’s official-hosted interview describes joining Philippe Dufour in 2001 and working on Simplicity finishing and assembly before establishing his own atelier.

The interview identifies design, prototyping, finishing and complicated-watch assembly, naming Greubel Forsey, H. Moser, Urban Jürgensen, MB&F and MCT among clients. 12

Reviving a name is not inheriting a company

Independent coverage dates Zwinz’s modern Winnerl revival to 2018. This is distinct from his 2004 service atelier and does not demonstrate corporate continuity from the nineteenth-century maker. Zwinz says his movement components were largely manufactured by Andreas Strehler to his specifications. Design, finishing and assembly must not be conflated with all-part manufacture.

The 2022 review documents the Founder’s Series numbered 596, 597 and 598; the official site describes a Tremblage version introduced in 2020. 2314
