All of the mechanical cuckoo clocks that are in our Online Shop have the VdS-authenticity certificate!
Black Forest clocks that are given this certificate must fulfill a high standard. One stipulation, for example, is that the clock is made exclusively in the Black Forest. But not only the proof-of-origin is enough to receive the certificate. The clock must be completely mechanical and all of the single pieces must be made in the Black Forest. There is no possibility to get one of these sought-after certificates for a quartz battery clock, or for a solar-powered clock.
