Definitions

  • Watches and timepieces are also known in which at least one time indicator member is constituted by a disc made of transparent material comprising an external toothing serving to drive it by a pinion. These are relatively large pieces by which we essentially seek a particular effect of the time display.
  • the 1.2 minute disc is made of transparent material, performs 1 rotation per hour and also includes a minute mark transferred or added in relief as well as a toothing around its periphery used for its training.
  • This disc can also be made of metal, but then it consists of an outer crown (invisible by the glass) connected to a central core by at least one arm constituting the minute marker and is obtained either by cutting or electroforming, this the latter making it possible to produce a very thin disc as well as very thin and very fine arms capable of creating a particular aesthetic of the switch and the "dial".
  • All the elements constituting the movement are located inside a rectangle inside which the hour indicator disc determines approximately a written circle separating two opposite zones occupied, one (fig.l) by the train finishing gears, the escapement and the balance wheel, the other (fig.2) by the winding and time-setting mechanism.
  • An intermediate gear 2 carried by the gear train 52 meshes with an intermediate pinion of the intermediate wheel 3 which meshes with the large medium pinion of the large medium wheel 4 meshing on the one hand with the minute disc 1.2 and on the other hand with the small medium pinion of the small medium wheel 5 which meshes with the second pinion of the second wheel 6 meshing with the exhaust pinion of the escape wheel of the escape wheel 7 actuating the anchor 8 located under the anchor bridge 53 and maintaining the oscillations of the pendulum 9 located under the cock 54.
  • the winding mechanism itself comprises the winding crown 60.1 secured to the winding pinion 10.1 located under the mechanism plate 55.1 held by the key 56.1 and meshing with a ratchet crown 1.6 whose toothing is identical to that of the hours disc 1.1 under which it is placed. Therefore the rotation of the winding crown, manually controlled, controls the rotation of the ratchet crown 1.6.
  • the time setting crown 60.2 can occupy two distinct angular positions, the first selecting the mechanism winding function, the second selecting the mechanism setting time function.
  • the time-setting cam 59 integral with the time-setting crown which it locks elastically in this position by a beak of the setting lever at hour 57, position the latter so that the free setting pinion 14, does not mesh with the ratchet crown 1.6 and the hour disc 1.1.
  • the time-setting lever is located above the mechanism plate 55.2 held by the key 56.2 and is acted upon by a rocking spring housed in the recess of the winding pinion and acting so that the rocking beak setting the time resiliently presses on the time setting cam.
  • the pawl 13 urged by the pawl spring 63 works with the teeth of the ratchet crown so as to allow rotation only in the one direction corresponding to the reassembly.
  • the angular movement of the time setting crown places the time setting cam in a position controlling the movement of the spout of the time setting rocker. in such a way that the time setting pinion simultaneously penetrates into the teeth of the ratchet crown and of the time setting disc, making them integral.
  • a spout of the time-setting cam acts on the pawl, the spout of which is released from the teeth of the ratchet crown which can then move in both directions.
  • the free time setting pinion working with the teeth of the ratchet crown and the hour disc has the effect of neutralizing the driving torque of the barrel spring because it acts on the one hand on a bung 1.3 secured to the 1.1 hour disc and on the other hand directly inside the ratchet-crown so that its degree of winding is a function of the displacement of one of the parts relative to the other.
  • the two parts becoming integral, it is then possible, by acting on the winding crown, to angularly move the hour and minute discs without modifying the degree of winding of the barrel spring.
  • part of the gear train is driven to a mobile comprising a calibrated friction in order to slide in both directions.
  • a protrusion of the lever constitutes a particular reference 57.1 appearing under the glass.
  • the time-setting pinion releases the teeth of the ratchet crown and the hour disc while the pawl again limits the rotation of the ratchet crown in the single winding direction.
  • the intermediate return is pivoted on an intermediate post driven into the gear train 52 which also carries all the upper bearings located, at least partially, in the same plane as the glass.
  • the lower bearings 3.2, 4.1, 7.1, respectively of the intermediate wheel 3, the large wheel 4 and the escape wheel 7 are driven into shaped holes (allowing the evacuation of cleaning liquids) closed off sealingly with plugs 51.1 driven into the bottom of the box and of the same material before the termination and the decoration thereof.
  • the anchor bridge carries the lower bearings of the small medium 5 and second 6 wheels as well as the upper bearing of the anchor.
  • the small medium wheel is constituted by an axis around which the small medium pinion freely rotates, secured to a friction spring, the outer arms of which slide at a determined torque on the small medium wheel driven onto the shaft so that the assembly is integral when the watch is running and that, when setting the time, the small medium gear can rotate in both directions without driving or overloading the small medium wheel.
  • the middle-bezel 62 comes to adjust elastically around the bottom of the box by means of a seal while box screws 66 ensure the assembly of the 'together.
  • box screws 66 ensure the assembly of the 'together.
  • the object of the invention essentially relates to the production of very flat watches, the particular aesthetics of this type of piece accommodates a marriage between the upper face of the watch and the crystal (and the hours disc) in order to use the entire surface for the graphics of the dial, the bezel and the bracelet, special shapes and decorations allowing a wide variety of shapes to be produced independently of the rectangular base of the movement.
  • this particular arrangement of the movement makes it possible to produce a watch ensuring chronometric performance, having a greater power reserve than known watches while being even flatter.
