oiling swiss lever

Methods 6 and 7:
There are two main alternative methods for lubricating the pallet stones:-

1. The lubricant is applied to the stones before the lever is fitted in place in
the movement. This requires care to avoid the oil being transferred to other
components.

2. The lubrication is applied to the stones after the lever is fitted using one of
the following methods:-
a. The lubricant is applied with the lever stationary before the balance is
fitted. The oil is applied to the impulse plane of the exit stone, usually
from the top and the lever moved from side to side to advance the
teeth. When three or four escape wheel teeth have passed the process
is repeated until all the teeth have been equally and evenly lubricated.

b. The movement is turned over and the exit stone is lubricated through
the inspection hole in the main plate and the lever moved from side to
side to advance the teeth. When three or four escape wheel teeth have
passed the process is repeated until all the teeth have been equally and
evenly lubricated.

c. A small amount of the lubricant is applied to each of the escape wheel
teeth. The movement is turned over and the escape wheel teeth are
lubricated through the inspection hole in the main plate. The oiler is
charged with oil / grease and then lowered to a position that allows
the moving escape wheel teeth tips to pass through the oil/grease, one
by one, until all teeth and pallet stones have been equally and evenly
lubricated.
A little on a few of the escape wheel teeth, by the action of the watch it will distribute the oil to the pallet pins this in turn will oil the rest of the teeth on the escapement wheel.
