This is slow motion vid of David Walter's amazing (D)W5 free pendulum clock, his interpretation of Philip Woodward's amazing W5 clock movement. The movement is showing a "miss", where the impulse to the slave pendulum on the right was not in synch enough to allow the Z shaped spring to catch. Hits and misses usually alternate.
