Description

This invention relates to a display device for a watch movement (mechanism), and this display device is A display wheel for the hour portion of hours, minutes, and seconds, which carries a display device for the hour portion of hours, minutes, and seconds in a given time zone (isochronal zone), and is intended to be clearly driven by the drive wheel of a clock movement, A chassis that rotates around the first main axis and is intended to display information in cooperation with a stationary display relative to the frame of the watch movement, A movable device mounted on the chassis in a manner that allows it to rotate around a second rotation axis different from the first main shaft, It includes a compensation mechanism configured to drive the movable instrument to a predetermined angular position relative to the frame of the watch movement, regardless of the angular position of the chassis around the first main shaft. This invention relates to a clock movement equipped with such a display device, and to a clock equipped with such a clock movement. Prior Art Such display devices have already been disclosed in prior art literature. For example, European Patent Application Publication No. 0921451 (Patent Document 1) describes a wristwatch comprising a chassis that defines an hour hand for displaying the current time. This chassis pivots around a first main axis of rotation and supports both a graduated dial and a minute hand for displaying the current time. Both the graduated dial and the minute hand pivot relative to the chassis around the same second axis of rotation. The graduated dial is driven to have the same orientation with respect to the frame of the watch movement at all angular positions of the chassis. The minute hand for displaying the current time is driven to display the minute portion of the current hour, minute, and second relative to the graduated dial. Chinese Patent No. 702422 discloses a similar wristwatch having an annular dial for displaying the hour portion of the current hour, minute, and second. For this purpose, the corresponding display device comprises a chassis driven by a watch movement and pivoting around a first main axis of rotation. This chassis carries an hour portion of the hour, minute, and second dial that pivots around a second axis of rotation, distinct from the first axis of rotation, so as to always have the same orientation with respect to the frame of the watch movement. An hour hand for displaying the current time is also mounted on this chassis in a rotatable manner and is driven to rotate around the second axis of rotation to display the hour portion of the current hour, minute, and second relative to the hour portion of Other prior art documents describe display units based on the principle described above. In particular, while these various configurations differ to a greater or lesser degree, the basic principle of the display unit is essentially the same. This is especially true of the two examples mentioned above, which, nevertheless, have been disclosed separately for over 20 years. Therefore, there is still a need to propose alternative display devices that enable watch brands to stand out from competitors with solutions that preferably offer enhanced readability compared to known devices.
