Assembling
the Movement
Assembling the Gear train
Since the surfaces of hardened steel arbors
*
are not treated, please
use the gloves included in the set. The gold-plated wheels can get
scratched if they come into contact with the harder material of the
steel tweezers.
The pre-assembled Gear train components and their arbor
pivots should be added to the ball bearings in the following
order and observing the installation position:
1.
Minute wheel
*
Compartment (10)
2.
Center wheel
*
Compartment (9)
3.
Spring barrel
*
Compartment (8)
4.
Fourth wheel
*
Compartment (11)
5.
Seconds wheel
*
Compartment (12)
Components
Preparation and Assembly of the Front Plate
The following components are needed:
◊
Front plate Compartment (29)
◊
Intermediate wheel pillar
*
Compartment (27)
◊
Cylinder-head screw M2 x 4 Compartment (27)
◊
5 x ball bearings
*
for front plate Compartment (7)
◊
3 x Allen countersunk-head screws M4 x 10 Compartment (27)
◊
4 x Washers Compartment (27)
◊
4 x Knurled nuts Compartment (27)
Lay the assembly base with the partially assembled movement
aside in order to prepare the second plate, known as the front
plate, for assembly.
Assembling the Intermediate wheel Pillar
On the outside (dial side) of the front plate the click spring
*
is
already pre-assembled.
The Intermediate wheel pillar
*
should now be put in the same area,
in the hole marked as position 1 (see photo below), and screwed
from below using a cylinder-head screw M2 x 4.
Safety Precaution:
The Spring barrel
may not be opened
due to danger
of injury.
Components
Adding the ball bearings to the Front Plate
Now the ball bearings should be put into the pocket holes of the
front plate. It is not possible to put them in the wrong place due to
the varying sizes of the bearings.
In case the ball bearings don’t seem to be stabilized enough in the
pocket holes, they can alternatively be added to the corresponding
arbor pivots. This prevents them from falling out when the front plate
is turned over.
