  • the second display 20 of this example is a date display, made by a needle, not shown in the figures, mounted on a shaft 210 coaxial with this moonwheel 11, this shaft 210 is integral with a calendar plate 21 driven by an intermediate date gear 521 qu 'drives the second pawl 52.
  • the mechanism 100 has the advantage of continuous operation, the oscillation of the control lever 5 is permanently, and this mechanism is integral with the hour wheel, and is very rigid. It can be advantageously made with identical components for the controls of the two displays: first pawl 51 and second pawl 52 identical to each other, first elastic return means 5110 and second resilient return means 5120 identical to each other, constituted by springs on the example of the figures. In the variant illustrated, the first pawl 51 and the second pawl 52 are arranged on either side of the plane of the control lever 5.
  • This mechanism 100 is shown here for day-time displays. It can be implemented for other periodicities, including monthly, or other.
  • This mechanism 100 has the advantage of being able to be coupled with a fast correction mechanism, without having to fear any moment of impossibility of correction, because the disengagement on the control makes it possible to carry out a correction at any time.
  • the invention also allows the easy positioning of a complication remotely relative to the axis of the movement.
  • the eccentric moon phase combined with a coaxial display of the date, can occupy any free position at the dial of the watch, while remaining very visible, and constitute an easy complication to integrate into an existing movement.
  • This dual control is very compact, and includes only components achievable in a very conventional manner, with a moderate cost.
