Assembling
the Movement
44
45
To add the escapement, it is best to only grasp it by the base plate
or on the balance cock.
Before adding it to the movement, remove the folded strip of paper
for transport security of the balance using the tweezers.
Carefully thread the escapement into the hole in the direction of the
Seconds wheel
*
inclined from the upper end of the front plate as
shown in the illustration. Both the fitting pins found in the base plate
of the escapement should now find their way into the corresponding
holes on the front plate.
Please be especially careful when securing the escapement. The
screwdriver should not slide and inadvertently damage the sensitive
components of the escapement.
Take care that the escape wheel pinion engages the Seconds wheel
and the escapement lays flat on the front plate.
Caution:
Please be careful
when handling
the escapement,
making sure that the
sensitive balance,
balance spring, and
the filigreed escape
wheel are not
touched or damaged!
Caution:
Only apply a slight
amount of strength
when adding the
escapement. The fili-
greed components of
the escapement can
easily be damaged!
Caution:
Don’t put your fingers
between the plates
and wheels. You
could be injured by
the quickly rotating
wheels!
Caution:
Only test the
escapement if the
plates and ratchet
wheel cock are
tightly secured!
The escapement can now be carefully
screwed to the front plate using two
cylinder-head screws M2 x 4.
So that the escapement can perfectly fulfill
its function, it is imperative that it lay flat on
the front plate and be tightly secured.
Testing the Escapement
Put the movement in front of you on the level workspace in
an upright position. Now carefully tension the mainspring
*
by 2-3 teeth of the ratchet wheel
*
so that the balance begins
to move using the winding key in the clockwise direction.
P
Okay
If the escapement does not begin to move,
please do not continue tensioning the mainspring,
but rather once again examine whether the escape wheel
pinion is engaging the Seconds wheel
*
. If you are unsure,
remove the escapement and add it again to be sure.
Ensure that the mainspring is not tensioned after removing
the escapement. To avoid unnecessarily straining the
Gear train
*
, you can simply stop it by using your fingers on the
pivot of the second hand extending out from under
the movement.
The Balance’s Amplitude
Now tension the mainspring somewhat further and test
the amplitude
*
of the balance
*
. This should move evenly
and the balance spring
*
should also “breathe” more evenly.
The balance will move from its center to its inversion point
about 220 degrees.
