  • the isolation device LI may be arranged to act on an end L200 of the probe L2 and / or to act by obstacle on the probe.
  • the configuration, including the position, of the correction element and the configuration, including the position, of the storage control element determine the configuration, including the position, of the isolation device.
  • the configuration, including the position, of the isolation device, and the configuration, including the position, of the storage control element determines the configuration, including the position, of the probe.
  • correction devices can be associated to correct more than one temporal information, including information that is kinematically related to each other, for example the indications of hours and minutes.
  • these devices can be controlled by a single pull tab T and a single control cam RC so as to drive in synchronization isolation levers specific to each of the display members of the stored time information.
  • the isolation levers LI and the pull tab T may form a single kinematic chain.
  • the blocker could be actuated directly by a control element such as a pusher, without implementing a column wheel.
  • a control element such as a pusher
  • the stored information can be displayed only when the user acts on the control element.
  • the blocker LB can be arranged so that it can lock the lever L1 regardless of the position of the lever L1 in "memorizing" phase. In other words, in the phase of storage ", the blocker LB can be arranged so that it can stop the display member S 'regardless of the position of the display member S'.
  • the lever device L can be manufactured in one piece or be monobloc.
  • the first elastic element R is formed by an elastically deformable part, in particular an elastically deformable part separating the lever L1 and the probe L2.
  • "storage of a temporal information” preferably means an action of storing a temporal information.
  • This storage action is preferably triggered by an action of the user.
  • This storage action preferably relates to the storage of current or instantaneous time information during the action of the user.
  • new temporal information can be stored.
  • the display of this stored time information can be maintained.
  • the storage of a temporal information may consist in freezing the current or instantaneous temporal information. Other members may continue to display the current time information when some are frozen or blocked to indicate the stored time information.
  • the first elastic element and the second elastic element are distinct.
  • the probe L2 can be articulated or pivoted on the lever L1.
  • a positioning of display members in one or more random positions or defined once and for all, that is to say in one or more positions that are not definable or non-modifiable by the user, as can be found in mechanisms display on demand, does not constitute a storage within the meaning of the invention.
