    description
    FIELD OF THE INVENTION The present invention relates to a watch with a clutch between a rotatable outer ring and an actuating shaft according to the preamble of claim 1. This relates in particular to a watch with a housing and an actuating and winding device, the actuating device and elevator device, a rotatable outer ring which has an annular toothed section and is rotatably mounted on said housing, an actuating shaft which is arranged essentially radially with respect to the housing, an adjusting knob, and a drive with a toothing which engages with said toothed section of the rotatable outer ring and serves to establish a kinematic connection between the rotatable outer ring and the actuating shaft, said drive being axially non-displaceable along the axis of the actuating shaft between a first stop and a second stop which are fixedly connected to the housing, angeo rdnet is.
    BACKGROUND OF THE INVENTION AND PRIOR ART In general, the invention relates to the field of operating elements on the watch case of wristwatches, which have been known in principle for a long time and in many different embodiments. In the case of large wristwatches, the controls on the watch case, such as the case crown, are usually rather large in relation to the case diameter and therefore have the ergonomic advantage that the classic functions of the time and date settings for the watch wearer are easy to accomplish.
    In watches with a smaller diameter, these controls are to be made smaller for technical and aesthetic reasons. This has the consequence that the operation of smaller wristwatches is made more difficult ergonomically. In addition, the sealing rings, as the term already expresses, are so tight and strong on the adjusting shaft in waterproof watches that the resulting higher friction additionally complicates operation on smaller crowns. These impairments can be so great that some of the wearers can no longer operate the watch properly. It is desirable to solve this problem.
    In the past, therefore, watches with a coupling between a rotatable outer ring and an actuating device and / or an elevator device have been proposed several times, since, particularly in the case of watches with a smaller diameter, the actuation of an outer ring with a large diameter is easier to carry out than the actuation of a small crown head. Various approaches have been taken to implement such mechanisms in a watertight manner.
    For example, the Swiss patent CH 72 852 describes a mechanism with a selectable coupling between a rotatable outer ring and the elevator or the actuator, by means of a rocker. However, this solution requires a specific clockwork.
    The Swiss patent CH 106 583 discloses a watch without an elevator shaft, in which an outer ring is coupled by rotation in one direction with the time setting device. However, the outer ring cannot perform any other functions.
    From the European patent application EP 2010 972 a coupling mechanism between the outer ring and the timing device is also known, by means of which only the time setting can be accomplished.
    A generic watch is known from European patent EP 0 892 944. This document discloses a watch with a housing which carries a rotatable outer ring with an annular, toothed section, with an actuating shaft which has a section with a polygonal cross-section which is located outside the clockwork, with a drive which has a hole of a cross-section, which is complementary to that of said section, equipped and placed thereon, wherein the toothing of the drive is in engagement with the toothing of said annular portion, whereby a kinematic connection between the rotatable outer ring and the actuating shaft is established. Here, the drive is positioned axially between two stops firmly connected to the housing, said section having a polygonal cross-section of the actuating shaft being selected so long that said actuating shaft can move axially between at least two positions, one for the elevator and the other for the position of the Clock, whereby the kinematic connection between the outer ring and the actuating shaft via the drive mentioned is maintained.
    The disadvantage here is that the control shaft with the polygonal section requires a custom-made and not an existing control shaft for the clockwork can be used. Since the power transmission of the actuation of the outer ring takes place via the two above-mentioned polygonal cross sections according to EP 0892 944, which have relatively small dimensions, premature wear is to be feared here. Furthermore, in the embodiment shown, the adjusting shaft is connected to the crown head in a rotationally fixed manner, so that rotation of the outer ring causes rotation of the crown head, which leads to premature wear of the sealing ring, which is located in a groove on the outside of a bushing penetrating the housing, which Crown head houses, located, can bring with it. In addition, this arrangement of the sealing ring is disadvantageous because it is almost on the outside of the watch. It should also be mentioned that in this version the inner construction of the outer ring is disadvantageously located in the dry area.
    CH 714 912 A2 Finally, a similar construction is known from the Swiss patent application CH 710302, in which, however, the crown head is replaced by an outwardly protruding lever which is parallel to the plane of the clockwork and perpendicular to the elevator axis and above it arranged axis pivots.
    Despite the disclosure of known generic actuating and elevator devices, it is therefore still desirable to have controls on the housing of wristwatches that are structurally simple, robust and reliable, and also have a high level of water resistance.
    OBJECT OF THE INVENTION The aim of the present invention is therefore to avoid the aforementioned disadvantages and to provide a watch with an actuating and winding device which has both a degree of watertightness that is at least equivalent in comparison to the previously known solutions, and also the control Realized by at least one function and preferably more than just one function inside the watch in a safe, structurally elegant, flexible and space-saving manner without needing to change the movement itself, the actuating and winding device being ergonomically convenient to use, this especially for wristwatches of smaller diameters.
    Solution and Summary of the Invention According to the Invention The object of the present invention is characterized by the features mentioned in the characterizing part of claim 1. In a watch according to the invention, the actuating and elevator device has, in particular, a coupling shaft arranged between the actuating shaft and the adjusting knob, the coupling shaft being fixedly connected to the adjusting shaft and being axially non-displaceable and rotatable relative to the adjusting knob, the toothing of said drive is carried by a clutch wheel with an axial opening, and wherein the clutch shaft is axially slidably mounted in the axial opening of the clutch wheel, the clutch shaft being slidable between at least two axial operating positions with respect to the clutch wheel and in at least one axial position in which said kinematic connection is made between the rotatable outer ring and the actuating shaft, is rotatably connected to the clutch wheel. Thus, the kinematic connection between the outer ring and the actuating shaft according to the present invention is made by means of a workpiece, the coupling shaft, which has a much larger diameter than the actuating shaft. This coupling shaft can e.g. in a hole that receives the outward end of an adjusting shaft that has been adapted for a certain movement and already exists.
    In a particularly advantageous embodiment of the present invention, there is a seal between the guide bushing and the coupling shaft, consequently by means of sealing rings, which on the one hand have a much larger diameter than the small sealing rings, which can be mounted on an actuating shaft, and on the other, further on Inside the watch where they are less exposed to pollution than just liquids, especially water.
    The invention further relates to embodiments in which the clutch shaft relative to the clutch wheel axially between a position to the elevator and at least one position for setting the clock, preferably for setting the date and / or for actuating another function of the clock, such as such as setting the time, a time zone, a wake-up time, an alarm time, a diving time or the like, can be moved while maintaining the said kinematic connection. The invention also relates to embodiments in which the clutch shaft is axially opposite the clutch wheel between a position to the elevator, a position to set the time, a position to set the date and / or to operate another function of the watch while maintaining said kinematic Connection and a safe position without actuating a function of the clock, in which said kinematic connection is canceled, is displaceable. In the latter case, one of the above-mentioned positions, for example the innermost depressed position of the adjusting knob, can be a so-called neutral position in which rotation of the outer ring and consequently of the adjusting shaft, the clockwork and / or the other function of the watch controlled via the outer ring not activated.

    Detailed Description of the Invention Several embodiments of the invention will now be described in detail below with reference to the figures.
    Figure 1 is a partial perspective view of the watch case of a watch according to a first embodiment of the present invention, wherein the individual parts of the actuating and winding device of the watch are shown in an exploded view. The housing 1 has a bottom 2, a housing ring 3 and an upper housing part 4. The housing 1 carries an outer ring 5 which is rotatably mounted between the housing ring 3 and the upper housing part 4, the concealed underside of which has a toothing in the form of an annular toothed section 5a which normally extends over the entire circumference of the outer ring. In a variant not described in more detail, the teeth of the outer ring could also be on the side on its underside, i.e. towards the inside or outside of the watch, but always on the outside of the case and covered by the case. The top of the outer ring 5 is accessible to the wearer of the watch and preferably has grooves by means of which the outer ring 5 can be easily rotated. The housing ring 3 has a bore in which a cylindrical guide bush 6 is inserted in a form-fitting manner. The guide bush 6 has on its outer circumferential wall a projecting ring which forms a flange 6a which serves both as a stop for the guide bush 6 with respect to the housing ring 3 and as an inner stop for a clutch wheel 7. The clutch wheel 7 has a generally cylindrical outer wall 7a and has a radial toothing 7b at its end directed towards the inside of the clock. The clutch wheel 7 thus forms a drive with its teeth 7b and is designed in such a way that its teeth 7b meshes with the toothed section 5a of the outer ring 5 in permanent engagement. The clutch wheel 7 also has an axial opening with a two-part inner profile. The part of the inner wall of the axial opening which is directed towards the inside of the watch is cylindrical and surrounds the outer wall of the guide bushing 6. The part of the inner wall of the axial opening which is directed outwards has a polygonal inner profile. A mounting flange 8 with a circular opening is slipped over the cylindrical outer wall 7a of the clutch wheel 7 and, for example, fastened to the housing ring by two screws 9, the inside of the mounting flange 8 serving as an outer stop for the teeth 7b of the clutch wheel 7. The mounting flange 8 is also positively integrated in the housing ring 3.
    Furthermore, Figure 1 shows a clutch shaft 10. The portion 10a of the clutch shaft 10 directed towards the inside of the watch is cylindrical in shape. As can be seen for example from Figure 2a, this section 10a of the coupling shaft 10 is axially slidable and rotatable within the cylindrical guide bush 6. In each groove on the circumference of the cylindrical section 10a of the coupling shaft 10, two parallel sealing rings 13 are mounted, which are sealingly attached to the inner wall of the guide bush 6 and rotatable with the coupling shaft 10 about the shaft axis and slidably sliding along the shaft axis. The section 10a of the coupling shaft 10 directed towards the inside of the watch is also firmly connected to a coaxial actuating shaft 11. The nature of the adjusting shaft 11 is adapted to the clockwork. Such an adjusting shaft is state of the art and need not be described in more detail here. The outwardly directed part of the coupling shaft 10 has a section 10b with a polygonal outer profile. The polygonal inner profile of the inner wall of the axial opening of the clutch wheel 7 and the polygonal outer profile of the section 10b of the clutch shaft 10 are complementary and lie in the assembled actuating and elevator device in at least one of the axial positions of the clutch shaft 10 in such a way that the rotation of the clutch wheel 7 takes the clutch shaft 10. The outwardly directed end section 10c of the coupling shaft 10 is also of a hollow cylindrical shape such that it can be slipped onto an inner axial cylinder 12a of an adjusting button 12, as can be seen, for example, from FIG. 2a. The cylinder 12a has a groove on its circumference, into which, by means of an incision in the clutch shaft, a locking washer 14 is inserted. As a result, the coupling shaft 10 is not axially displaceable on the adjusting knob 12, but is rotatably arranged with respect to the latter.
    CH 714 912 A2 The operation of this embodiment of the present invention is shown in Figures 2a, 2b and 2c. Figure 2a shows an initial position of the adjusting knob 12 and thus the entire elevator and adjusting device, which corresponds to an elevator position of the adjusting shaft 11 in the clockwork. Figure 2b shows a first drawn position, which corresponds to a date division of the actuating shaft, and Figure 2c shows a second drawn position, which corresponds to a position of the hands. For example, the first drawn position is offset by 0.6 mm from the starting position and the second drawn position is also offset by 0.6 mm from the first. The adjustment of the control knob 12 and thus the clutch shaft 10 and the control shaft 11 on the part of the wearer of the watch into the desired axial position is done by manual pull on the control knob. In this case, the adjusting knob 12 is rotated linearly and radially from the center via a lower projecting flange shoulder 8a of the fastening flange 8, which serves as a rail and engages in a correspondingly shaped bulge on the adjusting knob 12, as can be seen in particular from FIGS. 2b and 2c moved outside. Because the adjusting knob 12 is thus secured against rotation relative to the housing 1, the usual corrugations, which practically every classic housing crown has, may be missing.
    From the comparison of Figures 2a, 2b, and 2c, the person skilled in the art recognizes that in the illustrated example of a watch according to the invention, from one position to the next, the polygonal outer wall of the first section 10b of the clutch shaft 10 on the polygonal inner wall of the axial opening of the clutch wheel 7 slides and the kinematic connection between the rotatable outer ring 5 and the actuating shaft 11 is maintained. With the corresponding axial position of the coupling shaft 10, the function desired by the wearer of the watch can be actuated by rotating the outer ring 5. In an example (not shown) of a watch according to the invention, the length of the first section 10b of the clutch shaft 10, i.e. whose polygonal outer wall, and / or the length of the polygonal inner wall of the axial opening of the clutch wheel 7 are changed such that the kinematic connection between the rotatable outer ring 5 and the actuating shaft 11 only in at least one axial position of the clutch shaft 10, for example in a position for Elevator, a position for setting the time, a position for setting the date and / or for actuating another function of the watch, is maintained, while in at least one further axial position of the coupling shaft 10 said kinematic connection is canceled. in this case, the watch has a safe position of the actuating and winding device without actuating a function of the watch, which is important, for example, in diving watches, the safe position preferably being the non-pulled rest position of the control button.
    From the comparison of Figures 2a, 2b and 2c, the expert also recognizes that the two in the grooves on the circumference of the cylindrical second portion 10a of the coupling shaft 11 sealingly mounted around the shaft axis sealing rings 13 on the inner wall of the guide bush 6 through the Actuation of the adjusting knob 12 with the coupling shaft 10 slide along the shaft axis, wherein the coupling shaft 10 and thus the sealing rings can be rotated about the shaft axis by actuating the outer ring 5. It should be noted here that an opposite arrangement of the sealing rings 13, i.e. would be possible in corresponding grooves of the inner wall of the guide bush 6.
    Figure 3 is a partial perspective view of the watch case of a second embodiment of a watch according to the present invention, wherein the individual parts of the actuating and winding device are shown in an exploded view. The housing 101 has a bottom 102, a housing ring 103 and an upper housing part 104. The housing 101 carries an outer ring 105 which is rotatably mounted between the housing ring 103 and the upper housing part 104, the concealed underside of which has a toothing in the form of an annular toothed section 105a, which extends extends over the entire circumference of the outer ring. The housing ring 103 has a bore in which a cylindrical guide bushing 106 is embedded in a form-fitting manner and has a flange 106a on its outer wall, which serves both as a stop for the guide bushing 106 relative to the housing ring 103 and as an inner stop for a clutch wheel 107. The clutch wheel 107 has radial teeth 107b. The clutch wheel 107 is designed in such a way that its toothing 107b meshes with the toothed section 105a of the outer ring 105 in permanent engagement. The flank of the clutch wheel 107 in the direction of the interior of the watch has an annular groove which surrounds the outer edge of the guide bush 106. The clutch wheel 107 also has an axial opening. The inner wall of the axial opening of the clutch wheel 107 has a polygonal inner profile. A fastening flange 108 is fastened to the housing ring 103 by two screws 109 and serves as an external stop for the clutch wheel 107. The fastening flange 108 is integrated in a form-fitting manner in the housing ring 103.
    Furthermore, Figure 3 shows a clutch shaft 110. The portion 110a of the clutch shaft 110 directed towards the interior of the watch is cylindrical in shape. As can be seen, for example, from FIGS. 4a, 4b and 4c, this section 110a of the coupling shaft 110 is axially slidable and rotatable within the cylindrical guide bushing 106. In a groove on the circumference of the cylindrical section 110a of the coupling shaft 110, a sealing ring 113 is mounted, which is sealingly attached to the inner wall of the guide bush 106 and rotatable with the coupling shaft 110 about the shaft axis and slidably slidable along the shaft axis. The section 110a of the coupling shaft 110 directed towards the interior of the watch is also fixedly connected to a coaxial actuating shaft 111. The nature of the actuating shaft 111 is adapted to the movement, such an actuating shaft being state of the art and need not be described in more detail here. The outwardly directed part of the coupling shaft 10 has a section 110b with a polygonal outer profile. The polygonal inner profile of the wall of the axial opening of the clutch wheel 107 and the polygonal outer profile of the section 110b of the clutch shaft 110 are
    CH 714 912 A2 are complementary and lie in the assembled actuating and elevator device in at least one of the axial positions of the coupling shaft 110 in such a way that the rotation of the coupling wheel 107 entrains the coupling shaft 110. The outward end portion 110c of the coupling shaft 110 is cylindrical and can be inserted into an inner bore 112a of an adjusting knob 112. The bore 112a has a projection which fits into an annular groove in the section 110c of the clutch shaft 110. As a result, the coupling shaft 110 is not axially displaceable on the adjusting knob 112, but is rotatably mounted with respect to the latter. The adjusting knob 112 has a noticeably rectangular shape, but is adapted to the outer shape of the fastening flange 108 and is axially slidably mounted in a complementary opening of the fastening flange 108. On the left and right, the fastening flange 108 has two lateral projections which form lateral stops against the fastening flange 108 and thereby define the non-drawn rest position of the front disk 112b of the adjusting knob 112.
    The operation of this second embodiment of the present invention is shown in Figures 4a, 4b and 4c. Figure 4a shows an initial position of the adjusting button 112 and thus the entire elevator and adjusting device, which corresponds to an elevator position of the adjusting shaft in the clockwork. Figure 4b shows a first drawn position, which corresponds to a date position of the actuating shaft, and Figure 4c shows a second drawn position, which allows a pointer position. In the second embodiment of the watch according to the invention, the adjusting knob 112 is adjusted with the aid of a rocker arranged to the side of the adjusting knob 112, in that the watch wearer can press the rocker, i.e. laterally on the adjusting knob 112, with his finger, around the adjusting knob 112 together with the coupling shaft 110 and Bring actuating shaft 111 into one of the above positions according to Figures 4b, 4c. Insofar as rockers for adjusting an adjusting shaft 111 in clocks are state of the art, the rocker used here is not shown in the figures and need not be explained in more detail. When the adjusting knob 112 is axially adjusted as far as the coupling shaft 110 and the adjusting shaft 111, the adjusting knob 112 is displaced radially outward from the center in a manner preventing rotation.
    From the comparison of Figures 4a, 4b, and 4c, the person skilled in the art recognizes that in the illustrated example of a watch according to the invention, from one position to the next, the polygonal outer wall of the first section 110b of the clutch shaft 110 on the polygonal inner wall of the axial opening of the clutch wheel 107 slides and the kinematic connection between the rotatable outer ring 105 and the adjusting shaft 111 is maintained. With the corresponding axial position of the clutch shaft 110, the function desired by the wearer of the watch can be actuated by rotating the outer ring 105. The explanations given in the first embodiment of a watch according to the invention regarding the possibility of the presence of a safe position, preferably in the non-pulled rest position of the adjusting button 112, apply analogously to the second embodiment.
    From the comparison of Figures 4a, 4b, and 4c, the expert also recognizes that in the groove on the circumference of the cylindrical portion 110a of the coupling shaft 110 around the shaft axis sealingly mounted sealing ring 113 on the inner wall of the guide bush 106 by the actuation of the adjusting knob 112 with the coupling shaft 110 slides along the shaft axis, wherein the rotation of the coupling shaft 110 and thus of the sealing ring 113 about the shaft axis can take place by actuating the outer ring. It should also be noted here that an opposite arrangement of the sealing ring 113, i.e. in a corresponding groove of the inner wall of the guide bush 106, would be possible.
    Figure 5 is a partial perspective view of the watch case of a third embodiment of a watch according to the present invention, wherein an external view of the actuating and winding device is shown in its initial position. Figure 6 shows an axial horizontal cross section of the device of Figure 5 along the axis of rotation of the actuating shaft 211. The housing 201 has a bottom 202, a housing ring 203 and an upper housing part 204. The housing 201 carries a rotatable between the housing ring 203 and the upper housing part 204 mounted outer ring 205, the concealed underside of which has a toothing in the form of an annular toothed portion 205a, which extends over the entire circumference of the outer ring. The housing ring 203 has a bore in which a cylindrical guide bush 206 is inserted in a form-fitting manner. The guide bushing 206 has on its outer wall a flange 206a which serves both as a stop for the guide bushing relative to the housing ring 203 and as an inner stop for a clutch wheel 207. The clutch wheel 207 has radial teeth 207b. The clutch wheel 207 is designed in such a way that its toothing 207b meshes with the toothed section 205a of the outer ring 205 in permanent engagement. The flank of the clutch wheel 207 directed towards the inside of the watch has an annular groove which surrounds the outer edge of the guide bush 206. The clutch wheel 207 also has an axial opening. The inner wall of the axial opening of the clutch wheel 207 has a polygonal inner profile. A fastening flange 208 is fastened to the housing ring 203 by two screws 209 and serves as an external stop for the clutch wheel 207. The fastening flange 208 is integrated in a form-fitting manner in the housing ring 203.
    Furthermore, Figure 6 shows a clutch shaft 210. The section 210a of the clutch shaft 210 directed towards the interior of the watch is cylindrical in shape. As can be seen from FIGS. 7a, 7b and 7c, this section 210a of the coupling shaft 210 is axially slidable and rotatable within the cylindrical guide bush 206. In a groove on the circumference of the cylindrical section 210a of the coupling shaft 210, a sealing ring 213 is mounted, which is sealingly attached to the inner wall of the guide bush 206 and rotatable with the coupling shaft 210 about the shaft axis and slidably slidable along the shaft axis. The one towards the inside
    CH 714 912 A2 of the clock-oriented section 210a of the coupling shaft 210 is also fixedly connected to a coaxial actuating shaft 211. The nature of the actuating shaft 211 is adapted to the movement, such an actuating shaft being state of the art and need not be described in more detail here. The outward part of the coupling shaft 210 has a section 210b with a polygonal outer profile. The polygonal inner profile of the inner wall of the axial opening of the clutch wheel 207 and the polygonal outer profile of the section 21 Whether the clutch shaft 210 are complementary and lie in the assembled actuator and elevator device in at least one of the axial positions of the clutch shaft 210 in such a way that the rotation of the Clutch wheel 207 takes the clutch shaft 210. The outward end portion 210c of the coupling shaft 210 is cylindrical and can be inserted into an inner bore 212a of an adjusting knob 212. The bore 212a has a projection which fits into an annular groove of the section 210c of the clutch shaft 210. As a result, the coupling shaft 210 is not axially displaceable on the adjusting knob 212, but is rotatably mounted relative to the latter. The adjusting knob 212 has a noticeably cylindrical shape with a circular front disc 212b and is axially slidably mounted in a corresponding opening in the fastening flange 208. This opening of the fastening flange 208 is complementary over the largest and upper part of its circumference to the front disk of the adjusting head 212. On the lower part facing the housing base 202, which corresponds approximately to a quarter circle, the fastening flange 208 has a cutout which allows access to the frontal pane.
    The operation of this third embodiment of the present invention is shown in Figures 7a, 7b and 7c. Figure 7a shows an initial position of the adjusting knob 212 and thus the entire elevator and adjusting device, which corresponds to an elevator position of the adjusting shaft 211 in the clockwork. Figure 7b shows a first drawn position, which corresponds to a date division of the actuating shaft 211, and Figure 7c shows a second drawn position, which allows a pointer position. In this embodiment, the adjustment of the adjusting knob 212 can be achieved with one finger by pulling the adjusting knob 212 laterally from below at the edge of the housing base 202 and bringing it into the desired position with a noticeable click. The adjusting knob 212 is shifted radially outward from the center so as to prevent rotation. The adjusting knob 212 is designed such that it is completely sunk in the elevator position, almost invisible in the opening of the fastening flange 208, and disappears laterally in the housing ring 203.
    From the comparison of Figures 7a, 7b, and 7c, the person skilled in the art recognizes that in the illustrated example of a watch according to the invention, the polygonal outer wall of the first section 210b of the clutch shaft 210 on the polygonal inner wall of the axial opening of the clutch wheel 207 from one position to the next slides while maintaining the kinematic connection between the rotatable outer ring 205 and the actuating shaft 211. With the corresponding axial position of the clutch shaft 210, the function desired by the wearer of the watch can be actuated by rotating the outer ring 205. The explanations given in the first embodiment of a watch according to the invention regarding the possibility of the presence of a safe position, preferably in the non-pulled rest position of the adjusting knob 212, apply analogously to the second embodiment.
    From the comparison of Figures 7a, 7b, and 7c, the skilled worker also recognizes that the sealing ring 213, which is mounted in the groove on the circumference of the cylindrical section 210a of the coupling shaft 210 about the shaft axis and is sealed on the inner wall of the guide bush 206 by the actuation of the adjusting knob 212 with the coupling shaft 110 slides along the shaft axis, wherein the rotation of the sealing ring 213 about the shaft axis can take place by actuating the outer ring 205. Also in this embodiment, it should be noted that a reverse arrangement of the sealing ring 213, i.e. in a corresponding groove of the inner wall of the guide bush 206 would be possible.
    A number of advantages are achieved by means of these features. On the one hand, an actuating and winding device of a watch according to the invention represents an operating element which is ergonomically very pleasant to use for the wearer of the watch, in particular also in the case of wristwatches of smaller diameter, whereby it is also designed to be aesthetically pleasing. On the other hand, a watch according to the invention has very good watertightness, this being achieved only by means of proven ring-shaped seals which are arranged between the coupling shaft and the guide bush. In particular, one advantage of the embodiment according to the invention is that the operating elements protect the clockwork in the housing by means of a few, preferably one or two, smaller seals on the actuating device, which significantly increases the quality of the waterproofness of the clock. In addition, the outer ring of a watch according to the invention is advantageously arranged in the wet area, and its toothed section can be in contact with the medium water. An actuating and winding device according to the invention, which, depending on the specific application of the associated watch, has a corresponding number of sealing elements, is preferably used in waterproof watches and diving watches, insofar as such watches are usually equipped with a rotatable outer ring anyway. In addition, control of at least one function, preferably more than just one function, is implemented inside the watch in a safe, structurally elegant, flexible and space-saving manner.
    An actuating and elevator device according to the second or third embodiment of the invention described above has a number of advantages and can be integrated into the outer wall of the central part of a housing in a much simpler and more space-saving manner compared to previously known mechanisms, since the extension of the adjusting knobs is at least one dimension smaller than that of conventional crown heads. The advantage is not only an aesthetic one, since there is no visible crown on the side of the watch case, but also another ergonomic one
    CH 714 912 A2
    Advantage that is literally obvious, as this can prevent unsightly, hard skin on the back of your hand for some watch wearers.
    In addition, the device can be installed in various installation constellations of clocks without significant structural changes to the clockwork and can therefore be used flexibly. Depending on the desired application of the device, the individual components of the device can be provided in kit form for simple and quick assembly and for subsequent delivery, which results in an economic advantage that should not be underestimated. The device also represents an interesting solution, both in terms of construction and in terms of production costs, due to the small number of components, which is less than ten parts without taking into account the fastening and retaining screws. The device is robust and is characterized by a safe functional sequence, whereby it can be integrated into a variety of clocks or used for a variety of applications.
