The invention concerns a watch 1 comprising a watch case 2, the watch case 2 containing a watch movement 6 and two dials 8a, 8b. The watch 1 further includes a casing ring 3 arranged inside the watch case 2, the watch movement 6 being mounted in the casing ring 3 so as to be suspended in a cantilever arrangement inside the watch case 2, said casing ring 3 supporting the two dials 8a, 8b.

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.

A running equation of time mechanism includes civil hour and minute hands to indicate civil time and a concentric true minute hand to indicate true time. The running equation of time mechanism includes an equation of time cam and a differential gear device, a first input of which is formed by a civil minute pipe on which a civil minute hand is pressed, and a second input of which is formed by the equation of time cam. The differential gear device includes a planetary reducer wheel set via which the civil minute pipe drives a civil hour pipe on which is pressed the civil hour hand, and a planetary multiplier wheel set via which the civil hour pipe drives a true minute pipe on which is pressed the true minute hand.

A display mechanism a wheel carrying, constrained to rotate with it, a first wheel and a snail-shaped cam, the mechanism having an active first state in which the first wheel is driven in rotation by a driving wheel and a zero reset second state in which it is no longer driven to allow it to return to a predefined position, associated with a predefined position of the display member, the display mechanism further including a feeler-spindle adapted to cooperate with the perimeter of the cam, the feeler-spindle and the perimeter of the cam being adapted and sized so that the feeler-spindle exerts on the cam, in the second state, a return force having a non-radial component adapted to return the first wheel to its predefined position.

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.

A watch including a watch case, the watch case containing a watch movement and two dials. The watch further includes a casing ring arranged inside the watch case, the watch movement being mounted in the casing ring so as to be suspended in a cantilever arrangement inside the watch case, the casing ring supporting the two dials.
