Definitions

  • the invention relates to a spring-spiral system for watch movement. It still concerns a watch movement including such a system. It also relates to a timepiece, including a wristwatch, including such a system or such a movement. Finally, it relates to a method of setting the benchmark.
  • the traditional assembly of a balance-balance oscillator within a clockwork movement is carried out by means of a set of parts predisposed on the balance bridge which are provided to allow its displacement in rotation, and thus allow a placing at the easy reference of the escapement such that at the neutral position, or equilibrium position, the center of the balance plate pin is on the line connecting the pivoting movements of the anchor, or the blocker, and of the pendulum.
  • the outer end of the spiral spring is usually fixed to the balance bridge by means of a fixing support, for example a stud holder, which is movable in rotation relative to the frame of the watch movement. Disassembly of this angular positioning member of the balance bridge induces the loss of the setting of the marker.
  • the patent application EP1798609A2 discloses a conventional stud holder on which is fixed the outer end of a hairspring.
  • This bolt carrier is assembled on a pendulum bridge. More particularly, it is pivoted to friction on the balance bridge by means of resilient means which are provided to cooperate with a guide portion of the balance bridge.
  • Associated elements such as a micrometer screw and a return spring make it possible to finely adjust the rotation of the bolt carrier relative to the pendulum bridge.
  • the setting operation is thus done in a conventional manner by the fine rotation of the hanger of the hairspring relative to the frame of the watch movement.
  • the disassembly of the pendulum bridge peg also induces the loss of the adjustment of the marker.
  • the patent application EP2437126A1 describes a hairspring whose outer end has come from manufacture with a connecting member intended to be fixed to an angular positioning member of a balance bridge. More particularly, this positioning member is guided in rotation on the balance bridge by means of a bore adapted to cooperate with a cylindrical portion of the bridge. Disassembly of this member of the balance bridge here induces the loss of the setting of the marker.
  • the coil spring is movable relative to the rocker arm independently of an angular positioning member.
  • the setting of the marker can here be performed by directly changing the angular position of the spiral, in particular through the connecting member of the spiral spring.
  • the disassembly of the pendulum oscillator induces here the loss of the setting of the marker.
  • EP2799937A1 discloses an angular positioning member of a spiral spring which is integral with a damper body.
  • the marking operation is performed by the angular displacement of the damper body, in particular by means of a specific drive zone of the damper body, which can for example be in the form of 'teeth or flats. Disassembly of the pendulum oscillator induces the loss of the adjustment of the marker.
  • the patent application EP2570868A1 describes a shaped oscillator and arranged to suppress any setting operation.
  • a hairspring, a large tray, a plateau pin, and a small tray are made in one piece so that the angular indexing of these elements does not require a priori adjustment of the oscillator after one time this one mounted within the movement.
  • the end outer spiral can be secured to a fixed part of the movement, for example the plate, the anchor bridge, or the balance bridge.
  • the peak of the outer end of the spiral spring may in particular be provided to fit within a piercing of the plate, and to be held axially by a plate attached to the plate.
