    Description: The present invention relates to a zeroing device for a chronograph. The zeroing device consists of a first zeroing unit consisting of a zeroing lever with zeroing lever arm and a zeroing lever bar. The zero lever latch has a first end and a second end.
    Furthermore, the present invention relates to a chronograph.
    In particular, the chronograph comprises a second wheel with a driving spring. Further, a pulse receiving wheel is provided, wherein the driving spring is adapted to engage in the pulse receiving wheel. A zeroing wheel is in constant engagement with the drive wheel. A minute wheel is in constant engagement with a momentum transfer wheel and a center minute hand is fixed to the minute wheel. The second wheel is permanently connected to a second shaft and a center second hand is permanently connected to the second shaft. A multi-function wave is oriented parallel to the second wave. The pulse receiving wheel and the impulse transmission wheel are coaxially fixedly connected to the multi-function shaft. A first zeroing unit consists of a zeroing lever with zeroing lever arm and a zeroing lever bolt. The zeroing lever latch has a first end and a second end, wherein the first end can be brought into and out of operative relationship with a zero neutral heart of the nulling wheel and the second end with a second neutral heart of the secondary wheel.
    A mechanical movement has as a central components of a barrel with tension spring, wheels, escapement and vibration system (balance) on. The barrel with tension spring provides the drive of the movement. The power is transmitted starting from the barrel via the gear train to the escape wheel, which represents a part of the escapement. The gear train drives the hands of the watch and translates the spring force stored in the tension spring into rotational motions of different speeds, indicating seconds, minutes, hours and so on.
    U.S. Patent US 3,903,686 discloses a chronograph with a second hand, a minute hand and an hour hand combined with a minute and hour counter and having the property that the second hand, the minute counter and the hour counter are at zero can be set.
    The German translation DE 69 830 930 T2 of the European patent EP 1 046 970 B1 discloses an intermittent feed mechanism in which a feed pawl is applied with a spring member on a first counter wheel. The feed pawl rotates in concert with a first counter wheel so that each revolution of the feed pawl detects a gear of a second counter wheel or a second counter intermediate wheel, thereby intermittently advancing the second counter wheel or counter wheel. This intermittent feed mechanism has a protruding part put on the feed pawl with a positioning hole being made in a member of the first counter wheel. When the projecting part is inserted into the positioning hole and the protruding part is driven into the positioning hole by a spring part of the feed pawl, the feed pawl is positioned.
    A chronograph, e.g. the "ETA Valjoux 7750" movement has at least one second and one minute hand, which can be stopped, reset to zero and, if desired, restarted. The display of the measured with the help of a chronograph time interval can be done by separate second and minute dials or coaxial with the actual hands of the clock arranged second and minute hands. In the case of coaxially arranged hands one speaks of a center second hand and a center minute hand.
    German Patent DE 10 2013 103 180 B4 describes a chronograph with a center second hand and a center minute hand. The chronograph has a second wheel with a driving spring and a pulse receiving wheel, wherein the driving spring is adapted to engage in the pulse receiving wheel. Furthermore, a drive wheel and a zeroing wheel are provided, wherein the zeroing wheel is in constant engagement with the drive wheel. The chronograph also includes a momentum wheel and a minute wheel with the minute wheel in constant mesh with the momentum wheel and the center minute hand firmly connected to the minute wheel. Finally, a second wave is provided, wherein the second wheel and the center second hand are firmly connected to the second wave. An oriented multi-function shaft is provided parallel to the second wave, with impulse receiving wheel, drive wheel and impulse transmission wheel coaxially fixedly connected to the multi-function shaft. Another component of the chronograph is the two-piece and rotatably mounted zeroing lever, which can be brought into and out of engagement with the minute neutral heart and the second neutral heart to effect a zeroing or resetting of the center minute hand.
    A disadvantage of the prior art zeroing devices is that full reset of the center minute hand and the center second hand can not always be achieved with a single press of the reset push button. A full reset of center minute hand and center second hand requires at least two presses of the reset pusher. There is also the risk that the excessive force exerted by the reset pusher may damage the linkage.
    In order to solve the above-mentioned problems, it is an object of the present invention to provide a zeroing device, with the one-time operation of the reset trigger safe and permanently unique zero position of the center minute hand and the center second hand is enabled.
    The above object is achieved by a zeroing device comprising the features of claim 1.
    Another object of the present invention is to provide a chronograph in which by a single operation of the reset pushers a secure and permanently unique zero position of the center minute hand and the center second hand is enabled.
    The above object is achieved by a chronograph comprising the features of claim 8.
    The zero adjustment device according to the invention comprises a first zeroing unit, which consists of a zeroing lever with a zeroing lever arm and a zeroing lever bolt. The zero lever latch has a first end and a second end. The zeroing device is provided with a second zeroing unit which is arranged in a Z coordinate direction above the first zeroing unit and operatively connected to the first zeroing unit.
    The main advantage of this invention is that can be zeroed by a spring-loaded zeroing lever by the two zeroing mechanisms, both in use and in operative relationship to each other, the Minutennullstellherz and Sekundennullstellherz. Furthermore, the force is indirectly redirected from the reset pusher to the zero-setting lever bolt via the cam and the second zeroing unit mounted thereon, so that it can be manually pressed into the zero position.
    The second zeroing unit comprises a pendulum rod, a joint carrier and a joint rod. The pendulum rod is deflected rotatably on a cam and on the articulated rod. The articulated rod is deflected rotatably on the joint carrier and abuts against an eccentric of the zeroing lever. The articulated rod itself is fixed in place. As already mentioned above, it is achieved by the first and second zeroing units that a rotary movement of the control cam is converted into a directed pressure movement to the minute neutral heart and the second zero heart. The cam itself sits on a control cam and is connected to this stationary. The control cam interacts with the zeroing lever arm of the zeroing lever.
    The zeroing lever latch is configured such that the first end is angled and the second end is flattened. In a zero position, the first angled end of the zeroing lever latch abuts a flattened portion of the minute zero heart of a minute wheel. The second flattened end of the zeroing lever bolt abuts a flattened portion of the second zero heart of a second wheel. It is advantageous that with the present invention even with increased friction by multiple rotation and associated Federzwangsauslenkung of gears, the zeroing or the zeroing movement to the two systems (first zeroing unit and second zeroing unit) are divided.
    The zero position of the center second hand and the center minute hand is effected by the fact that engages a cam contour of the control cam in a U-shaped recording on Nullstellhebelarm the zeroing lever by the rotational movement of the control cam. Further, the rotational movement of the control cam via the pendulum rod and the link rod to the eccentric of the zeroing lever exerts a force such that the first, angled end of the zeroing lever bar at the flattened area of the minute zero heart of the minute wheel and the second, flattened end of the zeroing bar at the flattened portion of the second zero heart of Second wheel abut. Thus, it is always ensured by the two zeroing units that zeroing of the center second hand and the center minute hand is accomplished by engaging the flattened areas of the minute zero heart and the second zero heart with the first end and the second end of the zero lever bar. The zero position can be repelled by pressing a reset button. Upon actuation of the reset pusher in an axial direction, the rotational movement of the control cam is effected via a transmission mechanism.
    The chronograph comprises a second wheel with a driving spring and a pulse receiving wheel, wherein the driving spring is adapted for engagement in the pulse receiving wheel. Furthermore, a zeroing wheel is provided, wherein the zeroing wheel is in constant engagement with the drive wheel. A pulse transmission wheel of the chronograph is in constant engagement with a minute wheel and a center minute hand is fixed to the minute wheel. The chronograph includes a second wave, with the second wheel and a center second hand fixed to the second wave. A multi-function shaft is oriented parallel to the second wave, with the pulse receiving wheel and momentum transfer wheel coaxially fixed to the multi-function shaft. For the zero position of the center second hand and the center minute hand, a first zeroing unit is provided, which consists of a zeroing lever with a Nullstellhebelarm and a Nullstellhebelriegel. The zero lever latch has a first end and a second end. The first end may be brought into and out of operative relationship with a zero neutral heart of the zero wheel and the second end may be engaged and disengaged with a second zero heart of the second wheel. According to the invention, a second zeroing unit is arranged above the first zeroing unit such that the second zeroing unit assists the first zeroing unit upon actuation of a reset pusher. This has the advantage that the first zeroing unit and the second zeroing unit are at the same time at the operation of the reset pusher in use. The two zeroing units thus convert a rotational movement of the control cam into a directed pressure movement of the two zeroing units. The additional force of the second zeroing unit thus provides for zeroing the center minute hand and the center second hand.
    The Minutennullstellherz is firmly connected to the Nullstellrad a zeroing. The second zero heart is firmly connected to the second wheel via the second wave.
    The second zeroing unit is constructed such that a pendulum rod, a joint carrier and a joint rod are provided. For the function of the second zeroing unit, the pendulum rod is deflected rotatably on a cam and on the articulated rod. The articulated rod is deflected rotatably on the joint carrier and abuts against an eccentric center of the zeroing lever. The articulated rod is fixed in place in the chronograph.

    In Fig. 1 is a partial perspective view of a chronograph is shown from above. The drive of the chronograph via a swivel drive (not shown), which brings the gear train of the clock in engagement with the second wheel 3. According to the invention, the impulse receiving wheel 6 and the coaxially arranged above drive wheel 7 are fixedly connected to a Mehrfunktionenwelle 18, which in turn is mounted in a above the drive wheel 7 arranged board (not shown) in the ruby bearing block 21. Fixedly connected to the multi-function shaft 18 is also the momentum transfer wheel 9, which is in constant engagement with the minute wheel 10.
    The driving spring 5 is connected in its impulse receiving wheel 6 remote from the fixed portion of the second wheel 3. The impulse receiving wheel 6 facing portion of the driving spring 5 is resiliently formed and provided for engagement in the impulse receiving wheel 6. In constant engagement with the drive wheel 7 is the zeroing 8, which is fixedly connected to the zeroing shaft 11. The zeroing shaft 11 is mounted in a circuit board (not shown). After a complete rotation of the second wheel 3, the pulse pickup wheel 6 is rotated by the driving spring 5 by one subunit. Via the drive wheel 7, the zeroing wheel 8, the momentum transfer wheel 9 and the minute wheel 10 are moved further, whereby finally the center minute hand 2 advances by one unit.
    The center second hand 1 is permanently connected to the second wave 4, wherein the second wave 4 in turn is firmly connected to the second wheel 3. The second shaft 4 penetrates the center of the minute wheel 10. The swivel drive (not shown) provides for a direct drive of the second wheel 3, whereby the second second shaft 4 and the center second hand 1 is moved.
    Another component of the chronograph is formed in two parts and rotatably mounted zeroing lever 12, the function of which will be explained in more detail with reference to FIG. 2. The zeroing lever 12 consists of a zeroing lever arm 12a and a zeroing lever bar 12b, the zeroing lever arm 12a being rotatably supported about the zeroing lever pivot point 19 and the zeroing lever bar 12b being rotatably connected to the zeroing lever arm 12a by the zeroing lever locking pivot 20. The zeroing lever 12b is in a plane with the Minutennullstellherz 17 and the Sekundennullstellherz 16. The Minutennullstellherz 17 is connected via the zeroing shaft 11 fixed to the zeroing 8, while the Sekundennullstellherz 16 is connected via the second shaft 4 fixed to the second wheel 3. To stop the chronograph, the swivel drive (not shown) is brought out of engagement with the secondary wheel 3 by means of a pusher (not shown). In addition, an operation of the pusher causes a suitable retaining means (not shown), such as a locking bar, to be engaged with the secondary wheel 3. By pressing the pusher so it comes to a standstill of center seconds hand 1 and center minute hand. 2
    To bring the chronograph 100 (see Fig. 3) for another time measurement in its zero position 106 (see Fig. 3), with the aid of a further pusher (not shown) of the locking bar (not shown) out of engagement with the Second wheel 3 brought. At the same time by the operation of the pusher of Nullstellhebelarm 12a and thus the Nullstellhebelriegel 12b pivoted in their respective plane by a small amount, whereby the zeroing lever bar 12b occurs in frontal contact both with the Minutennullstellherz 17 and with Sekundennullstellherz 16. As a result, the minute neutralizing heart 17 and the zeroing wheel 8 fixedly connected to the minute neutralizing heart 17 via the zeroing shaft 11 as well as the secondary zeroing heart 16 and the second wheel 3 permanently connected to the seconds zeroing heart 16 via the second shaft 4 are rotated until they are in their zero position again , This is the case when the first angled end 13 of the zeroing lever bar 12b bears against the flattened area 17 'of the minute zeroing heart 17 and the second angled end 14 of the zeroing lever bar 12b bears against the flattened area 16' of the second zero setting heart 16. With the movement of the zeroing wheel 8 in its zero position and the drive wheel 7, the pulse transmission 9, the minute wheel 10 and the center minute hand 2 are brought into their respective zero position. Similarly, with the movement of the second wheel 3 in its zero position and the center second hand 1 is brought into its zero position.
    Fig. 3 shows a plan view of a chronograph 100 to which the invention is implemented. The chronograph 100 has housed the movement (not shown) in a housing 110. The hours are displayed on an hour hand 112 and minutes are displayed on a minute hand 114. To stop the minutes and seconds past a start time, the center minute hand 2 and the center seconds hand 1 are provided which move around an axis 108 common to the hour hand 112 and minute hand 114. To start or stop the stopwatch function, a start / stop pusher 102 is provided. To bring the center minute hand 2 and the center second hand 1 back to a zero position 106, a reset pusher 104 is provided.
    Fig. 4 shows a bottom view of the part of the internal structure of the chronograph 100 of Fig. 3. Here, the reset pusher 104 is shown in operative connection with the zeroing device 200 according to the invention. The zeroing device 200 comprises a first zeroing unit 71 and a second zeroing unit 72, which are arranged in different and in the Z coordinate direction Z offset planes E71 and E72 (see FIG. 10) in the chronograph 100. As described in FIG. 3, the reset pusher 104 can be operated from outside the housing 110 of the chronograph 100. By operating the reset pusher 104 in an axial direction A, its movement is transmitted to a control cam 32 by means of a transmission mechanism 38. The movement of the reset pusher 104 is translated into a pivotal movement of the control cam 32.
    Due to the pivoting or rotational movement of the control cam 32, a movement or force is likewise transmitted to the first zeroing unit 71 and the second zeroing unit 72 of the zeroing device 200. In Fig. 5, the structure of the zeroing device 200 and the interaction of the first zeroing unit 71 and the second zeroing unit 72 is shown enlarged. The first zeroing unit 71 consists of a zeroing lever 12 with a zeroing lever arm 12a and a zeroing lever 12b. The zero lever bar 12 b has a first end 13 and a second end 14.
    As can be seen from Figs. 4 and 5, the first end 13 of the zeroing lever bar 12b of the first zeroing unit 71 is angled. The second end 14 of the zero lever bar 12b is flattened. In a zero position, in which the center minute hand 2 and the center second hand 1 (not visible in the illustration of FIG. 5) are exactly superimposed and aligned with the zero position 106 (see FIG. 3), the first, angled end 13 of the reset lever bar is located 12b at a flattened region 17 'of a minute zero heart 17 and the second, flattened end 14 of the zeroing lever bar 12b abuts the flattened portion 16' of the second zero heart 17. Likewise, the control cam 32 is arranged with respect to a U-shaped receptacle 15 of the zeroing lever arm 12a such that a cam contour 39 of the control cam 32 lies in the U-shaped receptacle 15 and does not touch the reset lever arm 12a.
    The second zeroing unit 72 includes a pendulum rod 31, a joint carrier 34 and a link rod 35. The pendulum rod 31 is pivotally articulated on the cam 33 and on the articulated rod 35. The articulated rod 35 is pivotably articulated on the articulated support 34 and abuts against an eccentric 36 of the zeroing lever 12. The joint carrier 34 itself is fixedly mounted.
    As shown in Fig. 4 representation (view from below of a portion of the chronograph 100) and shown in Fig. 5 representation of the zeroing device 200 can be removed, the Minutennullstellherz 17 via a zeroing shaft 11 fixed to the zeroing. 8 connected. Likewise, the seconds zero heart 16 via the second shaft 4 fixed to the second wheel 3 is connected. In the zeroing operation is achieved by the abutment of the angled end 13 of the zeroing lever bar 12b at one point of the outer contour 17A of Minutennullstellherzens 17 and by the abutment of the flattened end 14 of the zeroing lever bar 12b at one point of the outer contour 16A of Sekundennullstellherzens 16 that the flattened area 17th of the minute zeroing heart 17 with the angled end 13 of the zeroing lever bar 12b and the flattened portion 16 'of the second zeroing heart 16 coming into abutment with the second flattened end 14 of the zeroing lever bar 12b thus establishing the zero 106 of the center second hand 1 and the center minute hand 2. For reaching the zero position 106 thus the zeroing wheel 8 and the second wheel 3 are rotated accordingly.
    When the start / stop pusher 102 shown in Fig. 3 is pressed, a drive gear 22 (see Fig. 4) meshes with the second wheel 3 so that the center second hand 1 (not shown in Fig. 4) moves becomes. The minute wheel 10 (not visible here, as below the second wheel 3) is assigned a minute counter 24.
    Fig. 6 shows a top perspective view of a portion of the inner structure of the Chronographen100 with the inventive zeroing device 200, the center second hand 1 and the center minute hand 2 are in the starting position (zero position). The center minute hand 2 is fixedly connected to the minute wheel 10. Via the drive wheel 7, the zeroing wheel 8, the momentum transfer wheel 9 and the minute wheel 10 are moved further, whereby finally the center minute hand 2 advances by one unit.
    The drive of the second wheel 3 takes place in accordance with the manner described in Fig. 4. The driving spring 5 is fixedly connected to the second wheel 3 and cooperates with the pulse receiving wheel 6 with each full revolution of the second wheel 3. The pulse receiving wheel 6 and the coaxially arranged above drive wheel 7 are fixedly connected to the Mehrfunktionenwelle 18, which in turn is mounted in a above the drive wheel 7 arranged board (not shown) in the ruby bearing block 21. Fixedly connected to the multi-function shaft 18 is also the impulse transmission wheel 9, which is in constant engagement with the minute wheel 10, so that at each full revolution of the second wheel 3, the minute wheel 10 and thus the center minute hand 2 advances a position.
    In constant engagement with the drive wheel 7 is the Nullstellrad 8, which is fixedly connected to the zeroing shaft 11. Via the drive wheel 7, the zeroing wheel 8, the momentum transfer wheel 9 and the minute wheel 10 are moved further, whereby finally the center minute hand 2 advances by one unit. The center second hand 1 is fixedly connected to the second wave 4, the second wave 4 in turn being firmly connected to the second wheel 3. The second wave 4 penetrates the center of the minute wheel 10. The center seconds hand 1 and the center minute hand 2 are thus designed to be rotatable about a common axis 108.
    Below the gear train (such as the seconds wheel 3 and the pickup wheel 6) and offset in the Z coordinate direction Z, the zeroing device 200 is the first zeroing unit 71 and the second zeroing unit 72.
    Fig. 7 shows a perspective view of a part of the inner structure of the chronograph 100 from below. Here, the structure and the spatial arrangement of the inventive zeroing device 200 is illustrated. The center seconds hand 1 and the center minute hand 2 are in the starting position (zero position 106, see FIG. 3). The first zeroing unit 71 and the second zeroing unit 72 of the inventive zeroing device 200 are arranged offset in the Z coordinate direction Z to each other and yet mechanically in operative connection. In the zero position 106 of the center second hand 1 and the center minute hand 2 are superimposed and the zeroing lever bar 12b of the first zeroing unit 71 is located at its first end 13 on Minutennullstellherz 17 and with its second end 14 on Sekundennullstellherz 16.
    With reference to FIGS. 8 and 9, the position of the zeroing device 200 according to the invention is clarified when the start / stop pusher 102 (see FIG. 3) has been pressed. The zero-setting lever 12b of the first zeroing unit 71 is pivoted such that the first end 13 is not in operative connection with the Minutennullstellherz 17 and the second end 14 is not in operative connection with the Sekundennullstellherz 16. The cam contour 39 of the control cam 32 is now in contact with a contour 25 of the zeroing lever arm 12a. With reference to FIG. 9, the position of the second zeroing unit 72 relative to the first zeroing unit 71 can be seen. The pendulum rod 31 is rotatably connected to the cam 33 and the pivot rod 35. The pivot rod 35 is also rotatably connected to the hinge bracket 34. By the system of the articulated rod 35 on the eccentric 36 of the zeroing lever bar 12b is biased accordingly, so that thereby the zero position of the center second hand 1 and the center minute hand 2 is supported with an additional force.
    Fig. 10 shows a side view of a portion of the inner structure of the chronograph 100 with the inventive zeroing device 200. Here, the arrangement of the individual elements of the chronograph 100 and the zeroing device 200 in the Z coordinate direction Z is to be illustrated. Below the elements of the chronograph 100, the zeroing device 200 according to the invention is provided in the Z coordinate direction Z.
    The center second hand 1 is arranged in the Z coordinate direction Z over the center minute hand 2. The momentum transfer wheel 9 and the minute wheel 10 are arranged in meshing engagement with each other and in the Z coordinate direction Z below the center minute hand 2. Below the pulse transmission wheel 9 and the minute wheel 10, the further elements, such as e.g. Second wheel 3, driving spring 5 (see Fig. 3), impulse receiving wheel 6, drive wheel 7 or zeroing wheel 8, the chronograph 100 arranged in the Z coordinate direction Z.
    The zeroing device 200 is arranged in the Z coordinate direction Z below the second wheel 3, the pulse pickup wheel 6, the drive wheel 7 and the zeroing wheel 8. The first zeroing unit 71 comprising the zeroing lever 12, the zeroing lever arm 12a and the zeroing lever 12b is arranged substantially in a plane E71. The second zeroing unit 72 is arranged substantially in a plane E72. The plane E72 of the second zeroing unit 72 lies in the Z coordinate direction Z below that of a plane E71 of the first zeroing unit 71.
    The foregoing description of the chronograph 100 merely describes those mechanical elements required for the chronograph 100's stopwatch function. All other elements of the chronograph 100 required for the time indication by the hour hand 112 and minute hand 114 (see FIG. 3) have not been shown for clarity. Furthermore, the construction of a timepiece movement is well known to a person skilled in the art.
    Fig. 11 shows a plan view from below of a part of the inner structure of the chronograph 100 with the inventive zeroing device, wherein in addition to the illustration of FIG. 7, a compression spring 40 for spring loading of the zeroing lever 12 is shown. The zeroing device 200 according to the invention makes it possible for the center second hand 1 and the center minute hand 2 to be in the starting position (zero position 106, see FIG. 3). The zero-setting lever 12b of the first zeroing unit 71 rests with its first end 13 on Minutennullstellherz 17 and with its second end 14 on Sekundennullstellherz 16. So that this system is always reached at the zero position 106 of the center second hand 1 and the center minute hand 2, the compression spring 40 abuts with a free end 41 at a free end 12aE of the zeroing lever arm 12a, which is also operatively connected to the control cam 32. The compression spring 40 thus exerts a pressure on the free end 12aE of the nulling lever arm 12a bringing the first end 13 and the second end 14 of the zeroing lever bar 12b into engagement with the corresponding flattened portions 16 'and 17' of the secondary zeroing heart 16 and the minute nulling heart 17 , At a mounting end 42, the compression spring 40 is connected via at least one mounting means 43 to a circuit board 101 of the movement (not shown) of the chronograph 100.
    12 is a plan view from above of a part of the inner structure of the chronograph 100 of the inventive zeroing device 200. Here, in addition to the view from FIG. 8, a locking cam 60 is shown above the control cam 32 a detent spring 50 cooperates. The locking cam 60 is mounted floating on the control cam 32. The locking cam 60 is held by a V-shaped end 51 of the detent spring 50 in V-shaped locking recesses 61 of the locking cam 60 in position. The zeroing linkage can be brought by the rotation of the locking cam 60 to pressure. The rotation of the latching cam 60 takes place by interaction of a contour 65 of the latching cam 60 with the start / stop pusher 102 and / or the reset pusher 104 (see FIG. 3).
    The detent spring 50 tries to fully engage in the V-shaped detent recesses 61 and slides along the slope of the V-shaped detent recesses 61 along. This exerts a pressure on one side of the V-shaped latching recesses 61, resulting in a rotational movement of the latching cam 60. The rotational movement ends when the V-shaped end 51 of the detent spring 50 engages centrally in the respective V-shaped detent recess 61. In the event that the detent spring 50 does not engage centrally with the V-shaped end 51 in the V-shaped detent recesses 61, the detent spring 50 will try to turn the detent cam 60 in one direction. The detent cam 60 in turn exerts permanent pressure on the second zeroing unit 72 (see FIG. 11), which in turn presses on the zeroing lever arm 12a in the end position via the eccentric 36 (see FIG. 11). This pressure on the second zeroing unit 72 can also be generated by manual zeroing, which is performed by radial pressure on the detent cam 60 manually via the reset pusher 104. Both types of pressure on the second zeroing unit 72 and the Nullstellhebelarm 12a can act simultaneously or independently. At an attachment end 52, the detent spring 50 is connected via at least one mounting means 53 to a circuit board 101 of the movement (not shown) of the chronograph 100.
