Lederer

Bernhard Lederer is a German-born independent watchmaker based in Switzerland. His Central Impulse Chronometer uses two escape wheels that deliver impulses to the balance alternately, each with its own constant-force remontoir, an approach that follows the work of Breguet and George Daniels.

The catalog lists the CIC 39 InVerto in titanium, launched in 2025 and nominated in the Complication category of the 2026 Grand Prix d'Horlogerie de Genève.

Production is limited by the workshop's yearly output, so dealers check the papers.
