[edit] How it works

In this type of master clock, patented by Fischer of Zurich in 1900, the electrical circuit remains closed throughout, and every minute the armature of a simple dynamo, driven by the clock weight, is sharply rotated, sending a pulse of current through the impulse dials. Successive rotations are in alternate directions and so are the pulses of current.
