Early Synchronome master clock movement receiving impulse from the gravity arm roller via the impulse pallet. This occurs at thirty second intervals as the escape wheel and trip vane are rotated by the D-shaped gathering pallet jewel. Having fallen and made electrical contact the gravity arm is reset on its catch by the twin electromagnets. The final sequence is at 5 fps yet still fails to capture the rapid resetting of the gravity arm. 2 fps was rather too jerky to be useful. The short electrical impulse while the contacts are closed is used to drive slave dials and other apparatus in series with the master clock. Recommend viewing in "High Quality".
Thanks. :)
