Horological display mechanism with separate displays

A horological display mechanism (100) for a timepiece (1000), comprising a plurality of three-dimensional unit display supports (10) each of which is arranged for simultaneous display of at least a first variable on a first three-dimensional display (901) under action of a first control mechanism, and of a second variable on a second three-dimensional display (902) under action of a second control mechanism,

• wherein said first display (901) surrounds said second display (902) or vice-versa, said first and said second control mechanism being configured to be maneuvered independently of one another, and constituting separate mechanisms, one for controlling translational motion and an other rotational motion, or vice-versa, said display mechanism being arranged so that, at a given moment in time, only one first display (901) shows an actual value of the first variable, and only one second display (902) shows an actual value of the second variable,
• said display mechanism (100) comprising first optical means for informing a user which said first display (901) shows the actual value of said first variable, and comprising second optical means for informing the user which said second display (902) shows the actual value of said second variable,
• wherein, at each said unit display support (10) of said plurality of unit display supports, said first or second display (901;
• 902) comprises, in order to determine an actual validity thereof, an optical indicator (14) which is visible to the user only when the display (901;
• 902) bearing it displays the actual value of the variable displayed by the display (901;
• 902), and a flap (16) capable of moving between an activated position wherein said flap (16) reveals said optical indicator (14) and a deactivated position wherein said flap (16) conceals said optical indicator (14) from the user, and
• wherein said display mechanism (100) comprises an actuator (2), which is arranged to control the manoeuvring, into said activated position, of said flap (16) at only one said unit display support (10) at a time, and to control, at a same moment in time, a switching into the deactivated position or a holding in the deactivated position of said flaps (16) of all of the other said unit display supports (10).
