An information display device includes: a position changing unit that changes a position of an information indicator in accordance with a type of information to be displayed by the information indicator; and an operation unit that causes the position changing unit to change the position of the information indicator that represents one type of information to a new position that represents another type of information, the operation unit causing the position changing unit to perform a movement completion operation for indicating to a viewer that the type of information displayed has been changed, in accordance with the another type of the information to be displayed when the position changing unit finishes changing the position of the information indicator to the new position.

A wristwatch (an example of a timepiece) includes a small dial (an example of a dial) and a rotary disk (an example of a rotary member). The small dial includes a sun mark for displaying the state of the sun. The rotary disk covers the small dial and rotates in a 24-hour period. The rotary disk includes the sun state indicator that changes the visibility of the sun mark in accordance with the rotational position of the rotary disk. One of the small dial and the rotary member includes a plurality of numbers (an example of indexes) for indicating time. The other of the small dial and the rotary member includes a time indicator that indicates a number in accordance with the rotational position of the rotary disk. The time indicator and the sun state indicator are disposed relative to each other in a positional relationship such that the visibility of the sun mark by the sun state indicator corresponds to the state of the sun corresponding to the number indicated by the time indicator.

A timepiece includes at least one time-of-day hand rotatable relative to a first dial and a first pair of temporal calendar mechanical elements independently rotatable relative to each other, and relative to the at least one time-of-day hand. Controlled rotation of the respective temporal calendar mechanical elements is synchronizable relative to temporal calendar information on an external device.

A wristwatch with a gear train for rotatably advancing in cyclic steps a minute-units disk, a switching device for advancing a minute-tens disk and an hour ring which is advanced during one revolution of the minute-tens disk. The movement comprises a first and a second transmission chain connected to a release mechanism; the first transmission chain controls the second such that the second transmission chain transmits every minute a rotational movement force to a minute-units wheel. The release mechanism comprises a control disk, two release levers, each having a first and a second lever arm, and a release wheel. After each minute, a first lever arm falls from the control disk edge into a recess of the control disk and a second lever arm releases the release wheel, such that the second transmission chain rotates freely, allowing the minute-units disk to rotate one digit further.

A display mechanism for a timepiece movement includes a plate defining a general plane, the display mechanism including a support intended to be rigidly connected to the plate and including a bearing housing a pivot defining an axis of rotation and rigidly connected to a display member bearing at least one display surface intended to be rotated between at least first and second different positions about the axis of rotation and to be situated substantially in a plane parallel to the general plane in the first position so as to define a reading position, in which the conditions for reading by a user are optimal, the support being arranged so that the axis of rotation defined by the pivot is oriented so as to have an inclination of between 10 and 80 degrees with reference to the general plane.

Disclosed is a mechanical movement including an information display device including at least one indicator member for the information, mounted pivoting about a pivot axis A. The movement encloses a cavity receiving at least the indicator member, the cavity being arranged so that the indicator member is housed entirely inside the movement. The movement includes at least one mobile arranged pivoting coaxially with the pivot axis A and including an outer peripheral toothing, the mobile being housed in the cavity and arranged to carry the indicator member. The mobile includes a felloe including the outer peripheral toothing and defining an inner opening, the felloe carrying an arm passing radially through the inner opening in order to be mounted pivoting on the pivot axis A, the indicator member being represented on the arm. Also disclosed is a timepiece including such a mechanical movement.

A platform for displaying several mutually different horometric items of information, includes as many crowns as the horometric items of information to be displayed on the platform. Each of the crowns is arranged to receive an associated information support and is movable in rotation at a speed selected according to a horometric item of information displayed on the associated information support.

A linear clock and method of indicating the time includes twelve linearly arranged regions wherein each region includes an indicator termed a marker, which is capable of representing a unique hour with a twelve hour cycle or a block of time equal to a five minute increment. Interspersed with the twelve linearly arranged regions is a group of four indicators that are capable of representing a one-minute increment and collectively, up to four minutes.
