Description
The DuRoWe is a nominal 10.5 ligne movement with a directly driven center second,
which is distinctive by its jagged bride shapes.
The screw balance is beared in two inhouse Duroswing shock protection systems and has got
a hairspring, which is directly connected to the balance cock and can be regulated in its
effective length by a long regulator arm. The balance controls a conventionally constructed
pallet lever movement with directly driven center second and minute hands. The minute wheel
is located under an own bridge.
Since this construction required few bearing jewels, an additional three cap jewels (two for
the escapement wheel and one for the third wheel on the dial side) are used which leads to
a total of seventeen hewels.
On the dial side, there's, common for all better movements, a yoke winding system.
