    Technical area
    The present invention relates to the field of mechanical watchmaking. It relates, more particularly, to a mechanical watch comprising a mechanical device for measuring the physical activity of a user comprising a drive device comprising a pivoting element mounted freely rotating on its axis and arranged to be driven by the movements of the user during his physical activity, at least one physical activity display device, and at least one cog connecting the training device and the physical activity display device.
    State of the art
    We have known for a long time, in the field of mechanical watchmaking, mechanical pedometers provided with oscillating weights which make it possible to display a distance traveled by a user on a dial by means of a needle. The reset is done by turning the needle with your finger.
    [0003] In the modern world, electronic watches make it possible to display the number of steps, the distance traveled or the calories expended corresponding to the physical activity of the user. For this purpose, these watches include an accelerometer powered by a battery.
    [0004] In entirely mechanical watches, solutions have been proposed in order to have a mechanical device for measuring physical activity by means of an oscillating mass. For example, publication CH 713 195 describes a device for measuring physical activity making it possible to display, on angular sectors, that the physical activity of the user increases when he moves by means of retrograde hands. Retrograde hands indicate a greater or lesser increase in physical activity. However, they do not make it possible to give the user precise indications on the evolution of his physical activity at any time. In addition, the display on the angular sectors is limited, such that it does not make it possible to precisely display a measurement of the physical activity when the units of measurement used to quantify said physical activity reach large numbers.
    [0005] In addition, an oscillating mass, once set in motion by the movements of the user, always has the same oscillating movement, whatever the movements of the user, constructed and controlled during physical activity, or random and uncontrolled, for example when the user shakes his watch. Therefore, the mechanical device for measuring physical activity is always driven, regardless of the movement of the user, so that a physical activity is counted even if the user does not perform any physical activity. Physical activity is therefore not counted correctly.
    [0006] It is thus desirable to provide a mechanical watch comprising a mechanical device for measuring the physical activity of a user who can have a device for displaying the measurement of physical activity that is precise at all times, visible and dynamic, allowing the user to constantly and accurately observe the evolution of the measurement of his physical activity.
    Disclosure of Invention
    To this end, the invention relates to a mechanical watch comprising a mechanical device for measuring the physical activity of a user comprising a training device comprising a pivoting element mounted freely rotating on its axis and arranged to be driven by the movements of the user during his physical activity, at least one physical activity display device, and at least one cog connecting the training device and the physical activity display device.
    According to the invention, the physical activity display device comprises at least one physical activity measurement display disk, said physical activity measurement display disk being provided of a series of digits or numbers, an aperture arranged to display the digit or number displayed by the physical activity measurement display disc, the gear train being arranged so that said display disc the measurement of physical activity advances by one step to display in the window the next digit or number when the pivoting element completes a predetermined number of turns, said predetermined number of turns of the pivoting element being a function of a predefined number of user movements, the watch further comprising a mechanism for resetting the physical activity measurement display disc.
    [0009] Preferably, the physical activity display device comprises several physical activity measurement display discs connected kinematically to each other so as to digitally display the physical activity measurement. 'physical activity.
    Advantageously, the drive device is arranged so that the predetermined number of revolutions of the pivoting element corresponds to a predefined number of steps taken by the user.
    [0011] Depending on the variants, the physical activity measurement display disc(s) is (are) arranged to display the number of movements, and preferably steps, performed by the user and/or the energy expended by the user as a function of the number of movements performed by said user, and/or the distance traveled by the user as a function of the number of movements, and in particular as a function of the number of steps, made by said user, and/or an acceleration or deceleration undergone by the user during a movement, and in particular an arm movement, made by said user. To this end, the watch comprises one or more physical activity display devices respectively comprising a set of display discs and an aperture, and the corresponding gear trains, dedicated to each of the desired physical activity displays.
    [0012] More particularly, the watch according to the invention may comprise at least two physical activity display devices, respectively comprising at least one display disc and an associated window, and at least two associated gear trains, arranged to display at least two different measures of physical activity.
    [0013] According to a preferred variant of the invention, the watch comprises at least one first device for displaying the energy expended by the user comprising at least one physical activity measurement display disc arranged to displaying said energy expended by the user as a function of the number of movements performed by said user and a first window arranged to display the figure or the number displayed by said display disk(s) of the energy expended, and a second device for displaying the distance traveled by the user comprising at least one physical activity measurement display disc arranged to display said distance traveled by the user as a function of the number of movements made by said user and a second counter arranged to display the figure or the number displayed by the said disc(s) for displaying the distance traveled.
    [0014] The use of at least two display devices makes it possible to display at least two different measurements of the physical activity of the user.
    [0015] Advantageously, the pivoting element can be an oscillating mass.
    In another variant, the drive device may comprise a drum constituting the pivoting element and at least one heavy element arranged to be able to move freely inside the drum during user movements. In this configuration, only the movements built and controlled during a physical activity of the user make it possible to create a centrifugal force which is exerted on the heavy element, which by this centrifugal effect, comes to be pressed against the interior wall of the drum by causing it to rotate.
    [0017] Thus, the user has a mechanical watch that accurately displays the measurement of his physical activity according to the movements, and in particular the steps, that he takes, like a step counter.
    The present invention also relates to a watch comprising a drive device for a mechanism, said drive device comprising a pivoting element mounted freely rotating on its axis and arranged to be driven by movements of a user, said drive device comprising a drum constituting the pivoting element and at least one heavy element arranged to be able to evolve freely inside the drum during movements of the user.

    Embodiments of the Invention
    Referring to Figure 1, there is shown a mechanical watch 1 comprising a mechanical device for measuring the physical activity of a user. In this variant, the mechanical device for measuring physical activity comprises, as a pivoting element of its drive device, an oscillating mass 4 pivoting freely under the effect of gravity and arranged to be moved and driven by the movements of the user during physical activity. In the example shown, the oscillating weight 4 is placed at 12 o'clock.
    [0021] Advantageously, the watch 1 also comprises a barrel (not shown) arranged to be wound automatically by an automatic winding system by means of said oscillating weight 4. It is obvious that the oscillating weight 4 can be independent of any barrel and be used only for measuring physical activity, forming a module system. The barrel of the watch is then powered by another source of energy (another oscillating mass, manual winding, etc.).
    [0022] The mechanical device for measuring physical activity also comprises a physical activity display device 2 as well as a cog (not shown in FIG. 1) kinematically connecting the drive device, here comprising the oscillating weight 4, to the physical activity display device 2.
    [0023] The gear train comprises a first pinion driven by the oscillating mass 4 and a last moving part which cooperates with the physical activity display device 2, as will be described in more detail below.
    [0024] Advantageously, this last moving part can constitute the ratchet transmission 8, which then also meshes with the barrel ratchet (not shown). In a manner traditionally used in automatic winding systems, the gear train linked to the oscillating weight 4 includes an inversion system in order to always drive the barrel ratchet in the same direction. It is obvious that the ratchet transmission may not be used, the last mobile of the gear train linked to the oscillating weight 4 then cooperating only with the physical activity display device 2.
    According to the invention, the physical activity display device 2 comprises at least one physical activity measurement display disk 10, said physical activity measurement display disk 10 physical being provided with a series of digits or numbers, as well as a window 12 arranged to display the digit or the number displayed by the disc 10 for displaying the measurement of physical activity.
    [0026] In addition, in accordance with the present invention, and whatever the variants, the gear train connecting the drive device, comprising as pivoting element the oscillating weight 4 with reference to Figure 1, to the display disc 10, is arranged so that at least the physical activity measurement display disk 10 advances by one step to display in the window 12 the next digit or number when the pivoting element, here the oscillating mass 4 , performs a predetermined number of revolutions, said predetermined number of revolutions of the pivoting element, here the oscillating mass 4, being a function of a predefined number of movements of the user. By “turn” is meant a rotation of 360°, which can be done in fractions, possibly carried out in both directions, the angular displacements carried out in the two directions being added. In the present description, the number of revolutions of the pivoting element, here the oscillating mass 4, can be less than 1, equal to 1 or greater than 1.
    Advantageously, the drive device is arranged so that the predetermined number of revolutions of the pivoting element, here the oscillating mass 4, corresponds to a predefined number of steps taken by the user.
    [0028] More particularly, it can be considered that, for each step, the user who wears the watch 1 on his wrist, makes an arm movement at an average angle of 36°, so that an angle of 36° is considered as the average angle of the pivoting element, here the oscillating weight 4, for a step in a situation of daily walking or physical activity with constructed and controlled movements.
    According to the variants, the cog between the pivoting element, here the oscillating mass 4, and the display device, can be arranged so that the disk 10 for displaying the measurement of physical activity advances by a step to display in the window 12 the next digit or number when the pivoting element performs less than one turn, one turn or several turns, the numbers or numbers appearing on the display disc 10 being adapted accordingly. A suitably configured reduction cog can be used for this purpose.
    [0030] Preferably, the physical activity display device 2 comprises several physical activity measurement display disks, preferably at least three, connected kinematically to each other so as to digitally display the measurement of physical activity.
    According to a first variant shown in Figures 1 and 3, the physical activity display device 2 comprises three physical activity measurement display discs, namely a first display disc 10 measurement of the physical activity which cooperates with the cog connected to the oscillating weight 4, arranged to display the tens of measurement units of the physical activity, a second disc 14 for displaying the measurement of the activity physical activity in kinematic connection with the first disc 10 for displaying the measurement of physical activity, arranged to display the hundreds of measurement units of physical activity and a third disc 16 for displaying the measurement of physical activity in kinematic connection with the second disk 14 for displaying the measurement of physical activity, arranged to display the thousands of measurement units of physical activity.
    [0032] More particularly, as shown in Figures 2, 3 and 4, the first disc 10 is mounted on a first wheel set 18 which comprises a pinion 20 meshing with the ratchet drive 8 which here constitutes the last wheel set of the linked gear train to the oscillating mass 4, so that the movement is dragging. In another variant not shown, the ratchet transmission 8 may not be used and the pinion 20 then comes directly in connection with the last wheel set of the gear train linked to the oscillating mass 4. To display the tens of units of measurement of the physical activity, the first disc 10 is provided, on its face arranged on the side intended to be displayed, with a series of ten numbers that are multiples of 10, from 00 to 90, regularly distributed around its periphery. The first wheel set 18 includes a drive finger 22 intended to drive, once per revolution, a second wheel set 24, in the shape of a star, which carries the second disc 14, so that the drive is jumping. A jumper 25 ensures the maintenance of the second mobile 24. To display the hundreds of measurement units of physical activity, said second disc 14 is provided, on its face arranged on the side intended to be displayed, with a series of ten digits from 0 to 9, regularly distributed around its periphery. The second wheel set 24 includes a drive finger 26 intended to drive, once per revolution, a third wheel set 28, in the shape of a star, which carries the third disc 16, so that the drive is jumping. A jumper 29 holds the third mobile 28 in place. To display the thousands of physical activity measurement units, said third disc 16 is provided, on its face arranged on the side intended to be displayed, with a series of ten digits from 0 to 9, regularly distributed around its periphery.
    The discs 10, 14, 18 are friction mounted on their respective mobile 18, 24, 28, as will be detailed below.
    It is obvious that the training of the first mobile 18 can be jumping, or that the training of all the mobiles 18, 24, and 28 can be dragging.
    The three mobiles 18, 24 and 28 are arranged so that the numbers of the first disk 10 and the numbers of the second and third disks 14 and 16 are contiguous with each other to accurately display in the window 12 the measurement of physical activity from 10 to 10. It is thus possible to display an accurate measurement of physical activity from 0 to 9990 units, i.e. a large number of units.
    In the example shown, the first disc 10 cooperates directly with the ratchet return, and the three discs 10, 14, 16 cooperate with each other without intermediate return, but it is obvious that the kinematic chains can include intermediate gears if necessary.
    In this example, the cog linked to the oscillating mass 4 can be arranged so that the first disc 10 for displaying the measurement of physical activity advances by one step to display in the window 12 the multiple number of 10 following when the oscillating weight 4 makes a turn, said turn corresponding to ten steps of the user.
    In another variant, not shown, the physical activity display device comprises a first physical activity measurement display disc which cooperates with the gear train linked to the pivoting element, arranged to display the hundreds of physical activity measurement units, a second physical activity measurement display disk in kinematic connection with the first disk, arranged to display the thousands of physical activity measurement units and a third physical activity measurement display disk in kinematic connection with the second disk, arranged to display the tens of thousands of physical activity measurement units.
    The first disc is provided with a series of ten numbers that are multiples of 100, from 00 to 900, and the second and third discs are provided with a series of ten digits from 0 to 9, so as to display in the counter a precise measurement of physical activity from 100 to 100, from 0 to 99900 units, ie a very large number of units.
    [0040] In this case, the cog linked to the pivoting element can be arranged so that the first disc 10 for displaying the measurement of physical activity advances by one step to display in the window 12 the multiple number 100 following when the oscillating weight 4 performs a revolution, said revolution corresponding to one hundred steps of the user.
    In another variant shown in Figure 6, the device for displaying physical activity comprises a first disc 10 for displaying the measurement of physical activity which cooperates with the cog 50 linked to the element 52 of the training device 54 which will be described in detail below, arranged to display the physical activity measurement units, a second disk 14 for displaying the physical activity measurement in kinematic connection with the first disk 10, arranged to display the tens of physical activity measurement units and a third physical activity measurement display disk 16 in kinematic connection with the second disk 14, arranged to display the hundreds of measurement units of physical activity.
    The first, second and third discs 10, 14, 16 can be provided with a series of ten digits from 0 to 9, so as to display in the window a precise measurement of the physical activity of 1 in 1, from 0 to 999 units.
    In the variant of Figure 6, in order to make the display fun for the user, it is possible to provide a first target 16a, in red for example, on the disk 16 from hundreds to 000 which indicates that there is no physical activity and the system is at 0. At 500, the number 5 of the hundreds disc 16 is replaced by a second target 16b, in orange for example, to indicate that the daily physical activity is average. At 900, the number 9 of the hundreds disk 16 is replaced by a third target 16c, for example in green, which indicates that the physical activity has been carried out for the day.
    [0044] In this case, the cog 50 linked to the pivoting element 52 can be arranged so that the first disc 10 for displaying the measurement of physical activity advances by one step to display in the window 12 the following figure when the pivoting element performs a rotation of 360° for example, this angle of rotation corresponding to ten steps of the user, a rotation of 36° corresponding to the movement of the user for one step, during a walk for example. The display of 999 units will correspond to 10,000 steps.
    In another case, the cog linked to the pivoting element can be arranged so that the first disc 10 for displaying the measurement of physical activity advances by one step to display in the window 12 the figure following when the pivoting element performs a rotation of 36 ° for example, this angle of rotation corresponding to a step of the user.
    The discs 10, 14, 16 can cooperate with each other in the same way as described above, the discs 14 and 16 being driven by drive fingers, via the disc 10. Additional references between the discs can be provided if necessary. Flexible drive fingers integral with the axles of the discs can be used to be compatible with a mechanism for resetting the discs, as described below.
    In this variant shown in Figure 6, and also with reference to Figures 7a and 7b, the drive device 54 of the cog 50 and the display discs 10, 14, 16, comprises a drum 52 constituting the pivoting element and at least one heavy element 56 arranged to be able to move freely inside the drum 52 during the movements of the user.
    The heavy element 56 is independent of the drum 52. The heavy element 56 is for example a ball or a roller or any other shape allowing it to roll or slide freely on the flat bottom 52a of the drum 52. Several heavy elements can be expected.
    The drum 52 is mounted freely rotating on its axis A by means of a ball bearing 58 positioned in a housing 60 provided under the bottom 52a of the drum 52 in order to leave the bottom 52a of the drum free. The ball bearing 58 comprises a hub intended to be secured to a frame element of the watch, for example the plate, and an outer ring 62 secured to the bottom 52a of the drum 52. The outer ring 62 has external toothing 64 arranged to cooperate with the first mobiles of the gear train 50, which are two inverters in order to always drive the other elements of the gear train 50 in the same direction of rotation, and the display discs 10, 14, 16. A braking system can be provided to limit and adjust the pivoting of the drum 52. This braking system can comprise a friction spring or a spring bearing against the drum 52 or against one of the elements of the gear train 50. The force of the brake can be adjusted by an eccentric system positioned at the rear of the braking system in order to pivot the spring more or less in the direction of the drum. The force of the brake is adjusted during assembly of the watch, to adapt the inertia of the drum to the type of physical activity envisaged by the user or to his type of wear.
    Advantageously, the drum 52 has on its inner wall 52b a succession of notches 66 and three-dimensional prominences 68, arranged alternately, said prominences 68 projecting radially in the direction of the axis A. The notches 66 and the prominences 68 are arranged with respect to the axis A of the drum 52 so as to leave, inside the drum 52, a central space 70, with respect to the axis A, in which the heavy element 56 can move freely. Preferably, the notches 66 and the prominences 68 are arranged symmetrically with respect to the axis A of the drum 52.
    The notches 66 are arranged to be able to receive the weighing element 56.
    The drum 52 is closed by a lid (not shown).
    The drum 52 which turns freely on its axis A is balanced, so that it cannot drive the cog 50 alone.
    When the user activates in any position in a constructed manner, during physical exertion for example, the movements of the user apply a centrifugal mechanical force on the weighing element 56. By this centrifugal effect , the heavy element 56 moves outwards, in the direction of the inner wall 52b of the drum 52 independently of the position of the watch, and falls to the bottom of the notches 66 along the inner wall 52b, creating a torque between the heavy element 56 and the axis A of the drum 52. Thus, the drum 52 is driven in rotation, and will, in turn, drive the rotation of the gear train 50 and the display discs 10, 14, 16, according to the predetermined angle of rotation.
    Advantageously with respect to an oscillating mass, the drum 52 pivots but does not oscillate.
    [0056] If the user performs disorderly, unconstructed gestures, for example by shaking the watch or suddenly turning the wrist, the heavy element 56 bounces in a disorderly manner in the central space 70, on one side and from the other from the axis of rotation A of the drum 52, coming out of the notches 66, so that the rotation of the drum 52 is greatly limited, unlike an oscillating mass which will drive the gear train in any situation.
    [0057] Thus, only the constructed and controlled movements cause the display discs to rotate so that only the real physical activity is counted.
    This construction also offers the advantage of being shockproof for the measurement of activity units.
    The number of notches 66 and prominences 68 can vary. In Figures 6 and 7b, there are four notches 66 arranged in a cross and four prominences 68.
    [0060] Figure 8 shows another variant of the drive device, in which the drum 52 comprises six notches 66 and six prominences 68, and the heavy elements are two balls 56.
    [0061] The training device 54 comprising the drum 52 and the weighing element 56 is here described in association with physical activity measurement display discs and a reset mechanism, but it is well obvious that it can be used to drive any other suitable clockwork mechanism depending on certain movements of a user, and more particularly constructed and ordered movements, other than physical activity measurement display disks and without reset mechanism.
    [0062] When the pivoting element is an oscillating weight 4, the weight of said oscillating weight 4 is chosen to allow an average inertia to be adjusted according to the wearer of the watch. An adjustment can be obtained for example by means of a flyweight or any other suitable means.
    [0063] Similarly, when the pivoting element is a drum 52, the weight of the heavy element 56 is chosen appropriately.
    The remainder of the description applies regardless of the drive device.
    The disks 10, 14 and 16 for displaying the measurement of physical activity can be arranged to display the number of movements, and more particularly the number of steps taken by the user. The number of arm movements performed by the user can also be used to measure physical activity.
    It is also possible for the display discs 10, 14 and 16 for measuring physical activity to be arranged to display the energy expended by the user, in calories or joules for example, or to display the distance traveled by the user, according to the number of movements, and more particularly according to the number of steps, taken by said user wearing watch 1.
    In another variant, the disks 10, 14, 16 for displaying the measurement of physical activity can be arranged to display an acceleration or a deceleration undergone by the user during movements, more particularly during movement. an arm movement, made by said user, in G units for example, relative to the number of revolutions of the pivoting element.
    The watch according to the invention may comprise a single physical activity display device with a single set of display discs and a single window for displaying one of the physical activity measurements, such as the number of movements, and preferably the number of steps, the energy expended or the distance traveled.
    The watch according to the invention may also comprise at least two physical activity display devices, each comprising a set of display discs and a corresponding window as described above, as well as at least two respective cogs, arranged to display at least two different measures of physical activity chosen from among the number of movements, and preferably the number of steps, the energy expended and the distance traveled.
    It is possible to choose to display, for example, the energy expended in a first window and the distance traveled in a second window.
    [0071] To this end, as shown in Figure 5, the watch comprises a first display device 2 arranged to display the energy expended by the user, comprising a set or set of display discs 10, 14, 16 for measuring physical activity arranged to display said energy expended by the user as a function of the number of movements, preferably as a function of the number of steps, taken by said user as defined above, and a first window 12 arranged to display the number displayed by said disks 10, 14, 16 for displaying the energy expended, as described above. There is also provided a first cog (not shown) as defined above connecting the pivoting element of the drive device and the first physical activity display device 2, so as to display the energy expended.
    [0072] The watch also comprises a second display device 2′ arranged to display the distance traveled by the user, comprising a set or set of display discs 10′, 14′, 16′ of the measurement of physical activity arranged to display said distance traveled by the user as a function of the number of movements, preferably as a function of the number of steps, taken by said user as defined above, and a second window 12' arranged to display the number displayed by said discs 10', 14', 16' for displaying the distance traveled, as described above. There is also provided a second cog (not shown) as defined above connecting the pivoting element of the drive device and the second physical activity display device 2', so as to display the distance traveled.
    In another variant, the watch according to the invention can also comprise a device for displaying physical activity, comprising a first set of display discs, a corresponding window, and a gear train as described below. thereon, arranged to display a measure of the physical activity chosen from among the number of movements, and preferably the number of steps, the energy expended and the distance traveled, as well as a second set of display discs and a window corresponding as described above, the disc of the units of the second set of display discs being kinematically linked to the first set of display discs, by means for example of a gear train provided between the two sets of discs display. This embodiment variant makes it possible to display with the first set of display disks the first units chosen corresponding to the physical activity displayed, and the following units on the second set of display disks. For example, in the case of displaying a distance traveled, the first set of display discs is used to display the meters, decameters, hectometres traveled by the user, and the second set of display discs is used to display kilometers, tens of kilometers, and hundreds of kilometers. This allows a larger number of units to be displayed. It is the same with the other units of measurement chosen corresponding to the physical activity displayed (number of steps, calories, etc.)
    [0074] Moreover, in accordance with the invention, and independently of the type of training device, the watch 1 comprises a mechanism for resetting the discs 10, 14, 16, 10', 14', 16' of physical activity measurement display.
    Advantageously, the mechanism for resetting discs 10, 14, 16 for displaying the measurement of physical activity comprises, for each display disc 10, 14, 16, a heart of resetting 30, 32, 34 secured respectively to its display disc 10, 14, 16 of the measurement of physical activity, and mounted coaxially to the corresponding mobile 18, 24, 28 on which the disc 10, 14, 16 is friction mounted. It is the same for the display discs 10', 14', 16' if they are present.
    The mechanism for resetting discs 10, 14, 16 also comprises a reset control arranged to actuate each reset core 30, 32, 34 in order to position its respective disc 10, 14, 16 d display of physical activity measurement in initial position. It is the same for the display discs 10', 14', 16' if they are present.
    The reset command can be centralized to reset all disks 10, 14, 16, and 10', 14', 16' if they are present, at the same time. It is also possible to provide reset commands for each set of discs 10, 14, 16 or 10', 14', 16' if present, which can be operated independently of each other to reset each display of a physical activity independently of each other. A reset command can take the form of a centralized corrector provided on the case of the watch. The reset control is arranged to actuate flip-flop correctors, in particular correctors 36, 38, to control core reset flip-flops, in particular flip-flops 40, 42 actuating cores 30 and 34 respectively, the flip-flop and core reset flip-flop 32 not being shown. In a variant with several independent reset commands, it is possible to use correctors provided on the case of the watch for each set of discs 10, 14, 16 or 10', 14', 16', these correctors being able to be actuated independently one of the other. Advantageously, these same correctors or other correctors can also be arranged to manually increment the unit disks of each set of display disks. Thus, the displays can be used to show the count of other information when the „display of physical activity“ function is not used. For example, it is possible to display laps completed, or a number of goals scored.
    The mechanism for resetting discs 10, 14, 16, and 10', 14', 16' if they are present, allows the user, for example, to reset the display in the morning when he puts his watch back on, or before practicing his physical activity, for example before going for a walk.
    It is obvious that any other reset mechanism can be used.
    According to another embodiment not shown in which the drive device comprises an oscillating weight 4 which is also used to wind the barrel, the display device can take into account the evolution of the power reserve of said barrel. For this purpose, the watch may include a differential comprising a first input connected to the barrel ratchet and to the oscillating weight 4, a second input connected to the drum of the barrel, and an output connected to the physical activity display device, for example via a complementary gear train. The display device can then be used to display the power reserve displayed by an equivalent number of movements, and in particular steps, of the user, when he does not wish to monitor his physical activity. The power reserve is synchronized when the watch stops and the discs are reset.
    The present invention makes it possible to obtain a display of the measurement of physical activity that is particularly readable by the user, dynamic and direct, the user being able to constantly read on his mechanical watch the evolution of his physical activity with precision. by means of discs, whereas the progress of the physical activity units on a pointer display would go unnoticed by the user. In addition, resetting allows the user to know his physical activity with precision over a specific period, at a specific time of the day, or over an entire day for example.
    Finally, the training device comprising a drum and a heavy element makes it possible to count only and precisely the true physical activity of the user, and this in all positions of the watch.
