Last week traveling in Germany I visited the "Uhrenindustriemuseum" in Villingen-Schwenningen **LINK** . It is in the old Kienzle factory which closed in 1985. Most of the machines from around 1920 are still present and working. Best to bring ear protection to limit the noise if you take the tour which is done by old workers. The one in the picture makes the hammers for a alarm clock. Niko.
