A device for displaying a succession of periodic events, such as zodiac periors, which form an annual cycle, this display device including a periodic event indicator organ; a mechanism for managing a duration for displaying periodic events by the periodic event indicator organ, this management mechanism including a cam for managing a periodic event display duration arranged to control the change from the indication of a periodic event to the indication of a next periodic event by the periodic event indicator organ; a date indicator mechanism driven by a horological movement; a month finger controlled by the date indicator mechanism so as to advance the management cam by one pitch per month, and a periodic event finger disposed between the management cam and the periodic event indicator organ and arranged to drive the periodic event indicator organ during a change of periodic event.

A timepiece with a double-sided display, including a first display member and a second display member coaxial to the first display member and integral therewith with a first common arbor. The centers of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis. The first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back.

The invention relates to a timepiece comprising at least an hour indicator, a minute indicator, a movement arranged to drive the hour indicator and the minute indicator, a dial, a crown and an indicator for at least one time zone, housed inside a first case. According to the invention, the first case is rotatable inside a second case about an axis of rotation, so that a rotation of the first case in a clockwise or anticlockwise direction with respect to the second case allows a time zone to be chosen and the time in the selected time zone to be indicated.

A time display apparatus for indicating time in a plurality of time zones simultaneously, the apparatus includes a case having a compartment enclosed by a cover, the case having a dial member indicating a 12-hour time clock and a 24-hour time clock, a first wheel completing one revolution in 12 hours and coupled to an hour hand, a second wheel completing one revolution in 1 hour and coupled to a multi-zone minute hand having at least two different vertices, and a third wheel completing one revolution in 24 hours and coupled to a multi-zone hour indicator hand having at least two different indicators, wherein each vertex of the multi-zone minute hand indicates a different minute marking on the 12 hour time clock and each indicator of the multi-zone hour indicator hand indicates a different hour marking on the 24 hour time clock corresponding to different time zones.

A time display apparatus for indicating time in a plurality of time zones simultaneously, the apparatus including a dial member indicating a 12-hour time clock, a first wheel completing one revolution in 12 hours and coupled to an hour hand, and a second wheel completing one revolution in 1 hour and coupled to a multi-zone minute hand having at least two different vertices, wherein each vertex of the multi-zone minute hand indicates at least two different minute markings on the 12-hour time clock.

A horological mechanism with a first mechanism (100) and a first output wheel set (101), a second mechanism and a second output wheel set (102), for displaying a first or a second indication specific to the first mechanism (100) or second mechanism (200), by a switching and coupling mechanism (500), including, on a coupling arbor (937, 938), two input wheel sets (1; 2) connected to the output wheel sets (101; 102), a sliding wheel set moving under constant strain between these input wheel sets (1; 2), and cooperating alternately and exclusively, by clicking in a single angular position per revolution, with either one, selected under the action of a command from a user on a controller, to establish a driving connection between the input wheel set engaged with the sliding wheel set at the given moment in time, and a display means.

A horological mechanism (1000) with a first train (100) and a first output wheel set (101), a second train (200) and a second output wheel set (102), for alternately displaying on a display (800, 8, 28) a first and a second indication respectively specific to the first train and second train, by a switching and coupling mechanism (500), including two input wheel sets (1; 2) connected to the output wheel sets, which includes a sliding wheel set (5) capable of moving under constant strain between the two input wheel sets, and cooperating alternately and exclusively with either one, selected under the action of a command from a user, to establish a driving connection between the input wheel set engaged with the sliding wheel set at the given moment in time, and a display (800, 8, 28) to produce a switchable display.

A device for displaying a succession of periodic events, such as zodiac periods, which form an annual cycle, this display device including a periodic event indicator organ; a mechanism for managing a duration for displaying periodic events by the periodic event indicator organ, this management mechanism including a cam for managing a periodic event display duration arranged to control the change from the indication of a periodic event to the indication of a next periodic event by the periodic event indicator organ; a date indicator mechanism driven by a horological movement; a month finger controlled by the date indicator mechanism so as to advance the management cam by one pitch per month, and a periodic event finger disposed between the management cam and the periodic event indicator organ and arranged to drive the periodic event indicator organ during a change of periodic event.

A timepiece with a double-sided display, including a structure including, on a first side, a first display member, and, on a second side, a second display member coaxial to the first display member and integral therewith with a first common arbor, the centres of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis, aligned with the projection of the latter or coincident therewith, the first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back, leaving a visible area contiguous with a hidden area wherein the back is invisible to the user, or between the back and the mask, moving above the visible area or the hidden area depending on its angular position with respect to the common axis.
