The Black Forest Clock Association (Verein der Schwarzwalduhr – VdS) was founded in 1987 as Förderverein Schwarzwalduhr e.V.. It brought together manufacturers, suppliers, dealers, and collectors under one organization with the central goal of protecting the geographical origin and authenticity of the Black Forest clock.
This effort led to the creation of the registered collective trademark:
“Black Forest Cuckoo Clock – VdS.”
Only clocks handcrafted in the Black Forest and produced according to strict traditional standards may carry this seal, guaranteeing their authenticity and distinguishing them from imitations worldwide.

The VdS certificate is a mark of authenticity, origin, and quality for the original Black Forest cuckoo clock. Only clocks that are exclusively mechanical and crafted in the Black Forest may carry this certification.
Traditional craftsmanship is at the heart of each certified clock. Cases, carvings, façades, bay windows, balconies, and shingles are typically made of wood, while every clock contains a mechanical movement and components that bring to life the characteristic features of the cuckoo clock—such as the cuckoo call, moving figures, and ornamental details. Whenever technically possible, these parts are produced directly in the Black Forest.
This principle extends to all essential components, including cases, carvings, dials, hands, weights, whistles, gongs, springs, and fittings.
Beyond craftsmanship, VdS also guarantees peace of mind with a worldwide network of Service Stations available to customers—both during and after the standard 24-month warranty period. Each Service Station is supplied with original spare parts directly from the manufacturers, ensuring that every clock receives proper care, repair, and refurbishment to continue delighting for generations.
As an Official Dealer and Service Station of the Black Forest Clock Association (VdS), THE CUCKOO HAUS is your trusted partner. Every clock purchased from us is a genuine product, designed, developed, and built in the Black Forest—a timeless piece of heritage you can cherish with confidence.
