Abstract: A holding and indexing device for integration in a setting device of timepieces, including a fixedly-attached bushing, an axially-displaceable and rotatable shaft mounted within the bushing, a transmission element attached to the shaft end directed into the interior of the timepiece and allowing the drive of a timepiece part in the interior, and a resilient element exerting a preload force in the axial direction of the shaft. The device additionally includes an indexing ring attached to the shaft in an axially-sliding manner and having an indexing toothing. The transmission element, on a side face directed towards the ring, includes a side toothing engaged with the indexing toothing due to the force of the resilient element. In at least one direction of rotation of the shaft, applying force onto the indexing ring causes disengagement of the indexing and side toothings, thus allowing a position indexing of the timepiece part.

Abstract: A device for fastening a wrist strap, in particular a watch strap, to a watch case, the device having a linking member, to which a strap end member of the wrist strap can be fastened and the case-side end of which can be fastened to a wrist strap pin attached laterally to the case. A securing element, which is biased against the case and has an interlocking projection located thereon, is arranged on the linking member such that the securing element can assume two positions, a first, secured position, in which the wrist strap pin is positioned in an indentation in the linking member and the securing element prevents the linking member or the wrist strap from becoming detached from the wrist strap pin and from the case, and a second, opened position, in which the wrist strap pin can be guided out of or into the indentation.

Abstract: A device for fastening a wrist strap, in particular a watch strap, to a case, in particular to a watch case, the device having a linking member, to one end of which a strap end member of the wrist strap can be fastened and the other end of which can be fastened to a wrist strap pin attached laterally to said case. The linking member has at the bottom thereof an indentation which is appreciably elbowed in longitudinal section and opens into a groove which is suitable for receiving the wrist strap pin and is oriented transversely to the longitudinal axis of the wrist strap. A securing element, which is biased against said case and has an interlocking projection located therein, is arranged on the linking member in such a way that the securing element can assume two positions.

Abstract: A setting device (1) includes an outer crown body (11), an inner crown body (12) firmly connected to this, a coupling (13,14) mounted at the inner crown body, as well as a crown sleeve (15) at least partly enveloping the inner crown body (12) and the coupling (13,14), inside of which the inner crown body (12) is mounted in both axially adjustable and rotatable manner. The setting device (1) further includes an elastic element (16) exerting on at least one of the crown bodies (11,12) a force pre-tensioning it in its axial direction, the force of pretension of the elastic element (16) being determined as a function of the effective front surface (A) of the outer crown body (11), in order to allow for an automatic, axial change-over of position of the setting device as a function of the applied external pressure.

Abstract: An operating unit adapted to be incorporated into a watch with a main setting device, which comprises at least two engagement positions, namely one rest position and at least one pulled position, and with at least one auxiliary setting device. The invention is also concerned with all types of watches suitable for the integration of such an operating unit and comprising the unit, in particular a world time watch with an analogue indication of the time of the day and of a corresponding location for different time zones with an offset relative to the local time by a multiple of an hour or of half an hour and thus allowing a simultaneous and reliable reading of the time of the day for the indicated time zones and a simple, fast and reliable operation and setting of the watch.

Abstract: A watch, in particular a dive watch, having a movement (16) which is arranged in a watch case (12) and can be used to drive an hour hand (3) via an hour tube and a minute hand (4) via a minute tube in a fashion sweeping over a dial (1). Also present is a pressure detecting device for detecting the ambient pressure outside the watch case (12) and a display for representing the detected pressure values. There is arranged in the watch case (12) a mechanical pressure transducer to which the ambient pressure outside the watch case (12) can be applied and by means of which a mechanical depth measurement mechanism (17) of a mechanical display can be driven.
