The oscillating
weight,
held down
by
a
screw
gib and made
of antimagnetic
alloy,
is mounted on its
axle
located in the
center of the movement and
is
free to swing in either
direction.
Whether the weight turns clockwise
or counter-
clockwise,
winding
of the mainspring
occurs.
Mounted on
the
train
bridge,
named
for
this
reason,
«combined
bridge»,
the 'automatic
mechanism
consists of
the oscillating
weight and its
gear,
two reversing gear units
which transmit winding
to
the crown and ratchet wheels
by
the
intermediary
of
a
reverser
converting
wheel,
a reduction
gear and a driving
gear
for crown wheel.
Each reversing gear unit consists of a reversing gear and
a reversing gear
pinion,
the latter being held in position
by
a
spring.
Whichever
way the weight
turns,
the reversing
gear
meshes
with the automatic
train while the other
slips.
In
any
case,
a
fairly
continuous
self-winding
action will
follow.
Should the watch be wound by stem and
crown,
the crown
wheel will make the automatic
train
turn,
but both
reversing gear pinions will
slip,
therefore
causing no inter-
ference with the automatic
mechanism.
