Abstract: The invention relates to a mechanical oscillating system for watches, especially wrist watches, having a balance spring and an oscillating body.

Abstract: Automatic mechanical winding device for the driving spring of a mechanical clockwork of a wristwatch with an eccentric mass that can be swiveled on a joint, said mass having a center of mass that is radially offset from the axis of the joint, with gear means for converting the swivel or rotary motion of the eccentric mass into a motion that winds the driving spring.

Abstract: A crown for watches, especially wristwatches or pocket watches, the crown body which is provided on a winding stem is made up of two parts and includes of a first part which forms the grip surface of the crown and a second part. The crown body furthermore has a crown body thread and can be screwed to a penetration which is provided on the watch case for the winding stem.

Abstract: In the clockwork, according to the present invention, the bearing journals of the balance staff, and also of the pallet staff, have a larger diameter than in known clockworks, since a DLC coating of these bearing journals and the corresponding surfaces of the bearings provides for very low friction, which enables an increase in the bearing journal diameter without diminishing the function and accuracy. The enlargement of the bearing journal diameter results in improved shock-resistance in addition to making the elements provided for shock resistance in conventional clockworks (spring-mounted bearings for the balance staff) partially, or wholly, unnecessary.
