Agenhor, short for Atelier Genevois d’Horlogerie, is a Geneva-based independent horological atelier known not for making watches under its own name, but for creating some of the most innovative and poetic movements used by elite Swiss watch brands. Founded in 1996 by master watchmaker Jean-Marc Wiederrecht, Agenhor has earned a quiet but powerful reputation as one of the most inventive movement designers in modern horology.

Rather than pursuing commercial collections or retail boutiques, Agenhor has focused entirely on complications—developing and assembling ultra-complicated modules and complete calibres for maisons such as Van Cleef & Arpels, Hermès, MB&F, Fabergé, and Trilobe. Their creations are often hidden behind prestigious names but are unmistakable for those who know the language of mechanical art.

One of Agenhor’s most notable specialties is the integration of poetic complications, such as Van Cleef & Arpels’ “Poetic Complications” series, where narrative storytelling is conveyed through miniature automatons, starry skies, or dancers moving across the dial. These whimsical displays hide formidable engineering challenges, solved only through Agenhor’s deep understanding of mechanics and aesthetics.

Agenhor is also at the cutting edge of chronograph development. After years of research and prototyping, the company released the AgenGraphe in 2017—a revolutionary chronograph movement that reimagines everything from the gear train architecture to the location of the hands. Unlike traditional chronographs, which stack timing functions on top of the base movement, the AgenGraphe integrates all components into a single, perfectly balanced calibre. It features a central chronograph display, a patented clutch system, and a unique operating philosophy that enhances legibility and performance.

This calibre has been used in watches by Singer Reimagined, where its high-functionality chronograph pairs perfectly with the retro-futuristic aesthetic of the brand. With the AgenGraphe, Jean-Marc Wiederrecht and his team pushed the chronograph—arguably the most commonly produced complication—into uncharted territory, both mechanically and visually.

Agenhor’s work is deeply collaborative. The company often co-develops movements alongside brands, tailoring functions and layouts to perfectly suit each client’s vision. Despite working behind the scenes, Agenhor’s name is increasingly recognised among collectors and connoisseurs for its unparalleled mastery and artistic innovation.

Now joined by his sons Nicolas and Laurent Wiederrecht, Jean-Marc continues to lead a new generation of movement designers who see mechanical watchmaking not just as a legacy craft, but as a living art. Whether it’s a starry sky that tells time, or a racing chronograph with unheard-of mechanical logic, Agenhor is shaping the future of high horology—one calibre at a time.
