Problems solved by technology
However, these devices have the following significant disadvantage due to the fact that the length of the month is usually not a multiple of 7 of the length of the week: they require manual intervention by the user at the beginning of each month to readjust the day scale with the inscription on the date scale inscription, otherwise the calendar display will no longer be correct
[0005] Document EP1 351 105 of the same owner as document EP1 351 104 describes the same device from another point of view and is concerned in particular with the problem that a calendar display device of the type mentioned in the The advantage of viewing the data as a whole, but you cannot view the next month's calendar until the night of the last day of the current month
[0007] This simple explanation shows that the solutions of documents EP1 351 104 and EP1 351 105 are complex in their design, difficult to implement, expensive to manufacture and even partly remove the function of the device due to the fact that two separate date discs are used. The main benefits and aesthetic appeal, on the one hand to enable the automatic adjustment of the scale of the days of the week and the scale of the date at the beginning of each month, and on the other hand to avoid calendars of the type mentioned at the beginning of this introduction The display device does not allow extended viewing of calendar data near the end of the month
[0008] Apart from the device according to the above-mentioned document (but which has the main disadvantages explained above), the prior art does not seem to include a mechanism which makes it possible to provide the The two aforementioned advantages in calendar displays of the type, namely, on the one hand, the automatic calibration of the days and dates at the beginning of each month, and, on the other hand, the ability to view the calendar extendedly at any time, even near the end of the month data

Embodiment Construction
[0031] The present invention will now be described in detail with reference to the accompanying drawings, which show by way of example an embodiment of a calendar display device according to the present invention.
[0032] as in figure 1 As schematically shown in , the calendar display device according to the invention is to be integrated into a mechanical watch comprising a conventional watch movement and belonging to the category of mechanisms that allow the user to view calendar data throughout a given month . In particular, such a device is able to match the days of the month to the days of the week.
[0033] For this purpose, the device according to the invention comprises the traditional components of such a device, namely a first disc 1 (day disc) bearing a series of inscriptions representing the seven days of the week; and a second Disc 2 (date disc), this second disc 2 bears an inscription representing the day of the month. One 1 , 2 of the day disc 1 and the date ...

The present invention relates to a calendar display device for a mechanical watch piece, including a disk of days, carrying multiple series of inscriptions symbolizing the seven days of the week, a disk of dates, carrying inscriptions symbolizing the date of the month, a disk of months, carrying 12 inscriptions symbolizing the months of the year. One of the disk of days and the disk of dates acts as a dial by being fixed, whereas the other acts as a rotary disk by being arranged concentrically and rotatably in relation to the dial. The dial comprises an aperture, the disk of months is mounted rotatably and is driven by a watch movement of the watch piece. A hand placed is concentrically and rotatably in relation to the dial so as to indicate simultaneously a date and a day of the week. The device comprises a correction mechanism comprising equipment configured to advance and reverse the disk of months so as to allow modification of the month displayed on the dial in a bidirectional manner. The device also comprises a direct kinematic link between the disk of months and the rotary disk so as to make automatic an indexing between inscriptions on the rotary disk and inscriptions on the dial, depending on a month displayed. The present invention also relates to a watch piece comprising the calendar display device.
Description
technical field [0001] The present invention relates to a calendar display device, in particular to a calendar display device for a mechanical watch including a watch movement. series of inscriptions representing the seven days of the week; the second disc (the date disc) bearing the inscriptions representing the dates of the month; the third disc (the month disc) bearing the 12 months representing the year one inscription; one of the day dial and the date dial acts as a dial by being fixed, while the other acts as a rotating disk by being arranged concentrically and rotatably with respect to the dial, which includes an aperture that makes it possible to see the Inscription of the current month on a month disc rotatably mounted and driven by the watch movement of said watch piece, while hands are concentrically and rotatably arranged relative to said dial to simultaneously indicate the date and the days of the week. The invention also relates to a watch comprising such a cale...
