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.
