  • the invention relates to the field of display mechanisms for timepieces, in particular for complication timepieces.
  • Displaying the power reserve is a useful complication in the field of mechanical movement watches driven by at least one energy source such as a spring barrel, or the like.
  • a differential makes it possible to collect information on the charging and discharging of the barrel, and to transcribe them through an indicator, often consisting of a hand attached to a wheel driven by this differential.
  • the display or the power reserve display hand which moves in front of a graduated or imaged reference scale, rotates clockwise or anti-clockwise depending on the gain (winding of the watch) or loss ( rate of the watch) of power reserve.
  • the maximum and minimum power reserve indications can be read on the reference scale, which is generally attached to a dial, itself fixed and integral with the mainplate.
  • a mechanism such as friction (which can be incorporated in the differential), absorbs the rotations of the gear train relative to the needle in a fixed position on the maximum stop or minimum as appropriate.
  • the power reserve hand controlled by the differential, displays the level of instantaneous power reserve between the two extreme marks of maximum or minimum power reserve.
  • the differential mechanism is a proven, precise and reliable solution; however, this mechanism is bulky, in particular depending on the thickness of the watch, sensitive to shocks, and expensive. Any simplification alternative is therefore welcome.
  • the invention proposes to create a particular clockwork mechanism, in particular for a watch, comprising a display mechanism for the display of particular quantities not necessarily linked to the time measured by the clockwork movement, and in particular for the display of the power reserve of a mechanical watch.
  • the mechanism according to the invention dispenses with the presence of a differential, and simplifies the gear train. It is, again, designed to simplify its assembly on the movement of the watch.
  • the invention relates to a timepiece according to claim 1.
  • the invention relates to a timepiece 1000, in particular a watch, which comprises a timepiece mechanism 200, and a display device 100 for displaying at least one quantity relating to this timepiece mechanism 200.

  • these friction means 9 comprise at least one cup spring or the like.
  • two mobiles 1 and 2 are coaxial. More particularly still, in a particular variant where the clockwork mechanism 200 comprises a movement with a main output axis which is that of at least one of the displays of the timepiece 1000, the mobiles 1, 2, are coaxial to this main axis.

More particularly, the external projection 78 is bordered, beyond the second lateral abutment surfaces 7, 8, by second recesses 79.
  • the second mobile 2 is an inner ring, which is arranged to carry a central dial 26 indexed by feet 28, 280; more particularly these feet are asymmetrical to ensure polarization during assembly, and the correct positioning of the reference elements.
  • At least one of the mobiles 1, 2, carries an indicator 60, such as a needle, a marker, or the like, which is mobile facing a scale defining a minimum magnitude MIN and a maximum magnitude MAX; this ladder is carried by another mobile, respectively 2, 1, or by a plate 40 or a holding plate 50 that comprises the clockwork mechanism 200.

  • the display device 100 is a power reserve display device for displaying the energy level of an energy source comprising a barrel 30 or a set of barrels 30 mounted in series and which comprises the clockwork mechanism 200.
  • This clockwork mechanism 200 comprises a load train 201, which is driven by a winding shaft 301 which comprises the barrel 30 or the set of barrels 30; this load train 201 drives a winding indicator 1 constituting one of the mobiles 1, 2.
  • the load train 201 comprises, carried by the winding shaft 301 which is guided in a retaining plate 50, a drive transmission 303, which meshes with a first reduction wheel 304, which meshes with a second reduction wheel 305 which drives the first mobile 1, in particular a winding power reserve indicator in the application illustrated by the figure 7 .
  • the clockwork mechanism 200 comprises a discharge train 202, which is driven by a cover 310 or a drum that comprises the barrel 30 directly upstream of the display mechanism 100, and this discharge train 202 drives a disarming indicator 2 constituting another of the mobiles 2, 1.
  • the discharge train 202 comprises a barrel cover 310, which meshes with a primary wheel 31 which comprises an intermediate friction wheel, composed of this primary wheel 31 and a secondary wheel 32 which can be coupled by means of friction 9, in particular at least one spring or the like; the secondary wheel 32 meshes with a third reduction wheel 33, which drives the second mobile 2 in particular a decocking power reserve indicator in the application illustrated by the figure 7 .
  • the friction means 9 are inserted between the winding shaft 301 and the winding indicator 1, or/and between the cover 310 or drum and the unwinding indicator 2.
  • the figures illustrate a particular, non-limiting variant, where the display mechanism 100 provides a power reserve indication located in the center of the timepiece.
  • the invention makes it possible to display the power reserve using two concentric discs, one rotating only when charging the barrel, the other only when discharging.
  • the cooperation of the abutment surfaces on each side of the extremes, minimum and maximum, of the power reserve makes it possible, using the friction means 9, on the one hand to simultaneously drive the discs in rotation when the power reserve is maximum and if the user continues to control the winding, either by action on a control stem, or by movements of the wrist in the case of an automatic winding mechanism with an oscillating weight, and on the other hand to the discs to remain immobile when the power reserve device displays a zero value.
  • the combination of the two makes it possible to display the remaining power reserve level.
  • a first combination of mechanical stops when one of the mobiles catches up with the other, thus allows, during a complete and forced load of the movement (the user continues to turn the rod or to set the mass in motion oscillating, despite a barrel already fully loaded), to simultaneously drive the two mobiles in rotation (the first driving the second using the stop); the presence of a friction means 9 in the gear train allows disengagement and avoids any breakage.
  • the second combination of mechanical stops when the second mobile catches up with the first mobile, freezes the mobiles in position when these display the value zero. If, despite the display of zero information, the movement still has a few hours of power reserve, and if the movement continues to run, the same friction as mentioned above absorbs the rotation and spins in a vacuum. It is important to note that the discs must absolutely turn in the same direction and on average at the same speed for this type of power reserve display.
  • the clockwork mechanism 200 comprises at least two control gears 201, 202, which do not simultaneously control the rotation of the mobiles 1, 2, but a single control gear 201, 202, controls, at a given moment given, the rotation of only one of the mobiles 1, 2.
  • the control gears 201 and 202 respectively comprise outputs 3 and 4 rotating in the opposite direction, which is not an obligation.
  • the display of the power reserve is a useful complication for a mechanical watch, especially if this watch has calendar complications, because it allows the user to avoid the tedious resetting of calendar data, especially in the case of annual or perpetual calendar.
  • Another application relates to a particular display for a chronograph mechanism, with one of the moving parts displaying the instantaneous elapsed time, and another moving part displaying the maximum (or respectively minimum) value measured on a set of counts linked to the same event.
  • Yet another application relates to the display of altimetric values, for diving watches or even hiking: one of the mobiles displays the instantaneous depth or height in relation to a reference, and the other mobile displays the maximum depth or altitude reached.
  • the second gear train resets the altimeter indication.
  • the clockwork mechanism 200 is a watch movement comprising an upper part arranged to face the user
  • the display device 100 is an additional sub-assembly which can be inserted on the movement on the side of the upper part, and which can be easily positioned and immobilized on a plate 40 or a retaining plate 50 that the movement includes, by at least one key 55 and/or an eccentric lock 81, 82, cooperating with a bore 51 and/or a support surface 52 that comprises the retaining plate 50 or the plate 40.
  • this movement comprises at least one floor for driving a display, which at least one floor is surrounded by the mobiles 1, 2.
  • the clockwork mechanism 200 comprises at least one control means 300 usable by a user, such as a control rod or the like, to control a triggering of a first control train 201, 202, and/or a reset, to command the reset of another control train 202, 201.
  • a control means 300 usable by a user, such as a control rod or the like, to control a triggering of a first control train 201, 202, and/or a reset, to command the reset of another control train 202, 201.
  • the invention lends itself well to pre-assembly of the discs, to produce a removable subassembly that is easy to handle, for easy assembly and disassembly with respect to a clock movement receiving and controlling this display device 100.
  • the invention also provides satisfactory answers in in terms of resistance to shocks, ease of adjustment and control of swings; the mobiles are axially and radially independent of the other dials and display elements, they are axially independent of each other, and their only cooperation is their radial dependence and their angular drive one by the other.
  • the first mobile 1 is annular and constitutes an intermediate dial, which comprises an upper surface 11 visible to the user, and which can be surrounded by a fixed outer dial 210 of the timepiece 1000;
  • the second mobile 2 annular, carries a central dial 26 whose upper surface 21 is visible to the user, this central dial 26 comprising feet 28, 280, cooperating with housings 29, 290, of the second mobile 2, and which can be blocked by eccentric keys operated during pre-assembly of the removable sub-assembly, which then comprises the first mobile 1, the second mobile 2, the central dial 26, and the eccentric keys;
  • the first mobile 1 is advantageously enclosed axially between the second mobile 2 and the central dial 26: its axial movement is thus determined by construction, and strictly respected.
  • This removable sub-assembly can easily be positioned on a plate 40, or on a retaining plate 50 fixed to such a plate, which comprises the clockwork mechanism 200, in particular a movement, and be immobilized by several locks 81 or 82, in particular rotary locks 82 inside a clearance 820 that includes by example the retaining plate 50, which includes at least one stop boss 850 to limit the angular travel of a control arm that includes the rotary lock 82, as visible on the figures 16 and 17 which illustrate the holding of a peripheral web 24 of the second mobile 2.
  • a holding plate 50 is implemented, which surrounds the roadway in the case of a conventional mechanical movement, and which comprises a bearing surface 57 cooperating with low play with a bore 27 that comprises the second mobile 2, or vice versa.
  • a second variant is precisely that illustrated by the figures 16 and 17 : the removable sub-assembly is pre-assembled in an identical manner, and the second mobile 2 comprises a veil 24 at its lower part, also visible on the figure 11 , which is thus locked by at least two rotary locks 82. If the timepiece 1000 includes an outer dial around the first annular wheel set 1, it is easy to maintain this outer dial on the retaining plate 50 by at least two keys accessible from its periphery.
  • the first mobile 1 is still immobilized or at least limited axially by keys 81 or bolts engaged with the retaining plate 50, as seen on the figure 11 .
  • the assembly sequence is very simple, because it does not require any reversal of the clockwork mechanism 200: everything is done from a single side.
  • the removable sub-assembly is pre-assembled by bringing the first mobile 1 and the second mobile 2 into cooperation, the central dial 26 is attached, positioned by its feet, that the 'we stop with keys, in particular beak keys, this sub-assembly is positioned on the holding plate 50, on which it is locked: the functional antics and the divisions are ensured, the positions are correct, and the locking is effective against shocks.
