German Seth-Thomas Clock Movements

German Seth-Thomas clock movements are still available. Finding a new movement starts with the identification numbers off the back plate. The numbers need to be converted because they did not make any movements after 1950. Instead they were made by Hermle of Germany with the ST number system and ST name instead. So really its a Hermle in disguise and ST only marketed the clocks. The used the Seth Thomas name on the Hermle movements and married them to its clock case.
