Beginning of Right
Complementary Arc
The impulse pallet disengages from
the pallet fork, the balance oscillates
further and completes the outbound
complementary arc.
End of Right Complementary Arc
The balance transmits its dynamic energy
to the balance spring, comes to a stop at
the right point of inversion, and is accelerated
in the opposite direction by the energy
saved in the balance spring.
Discharge
The impulse pallet engages the pallet fork,
releases the escape wheel tooth at the
exit pallet via the pallet lever,
and causes the discharge.
Lift and Impulse
The escape wheel tooth leaves the locking
plane of the entry pallet and glides to the
impulse plane. The balance thereby receives
an impulse to keep oscillating from the
rotational motion of the escape wheel
via the pallet lever and impulse pallet.
Balance:
-30°, counterclockwise rotation,
completes the outbound complementary arc
Balance spring:
Takes on the energy from the balance,
thereby decelerating it
