The VdS certificate
The Verein die Schwarzwalduhr — the Black Forest Clock Association — certifies one thing, strictly: that a clock is mechanical, and that every essential part of it was made in the Black Forest. No electronics, no imported movement, no carving cast in resin. The certificate exists because the region's name is borrowed far more often than it is earned.
Every clock of this house carries the VdS seal. It is the floor beneath our own Urkunde, not the ceiling.
