Definitions

  • the present invention relates to a timepiece comprising a watch movement, a calendar mechanism and means for indicating the sunrise and sunset taking into account seasonal variations
  • the watch movement comprising a minute mobile, a timer wheel , an hours indicating member, and a mobile hours integral rotation of the hours indicating member and arranged to be driven by the minute mobile via the clockwork is at the speed of a turn in 12 hours, or at a speed of one turn in 24 hours
  • the calendar mechanism being arranged to be driven via the hours mobile and having means for displaying the date and means for displaying the month
  • the means for indicating the date sunrise and sunset including a sphere reproducing the globe, a support, and a circle mounted on the support concentrically to the sphere and arranged to indicate the position of the terrestrial terminator, the circle and the sphere being arranged to be driven so as to rotate relative to each other, at the rate of one revolution per 24 hours, about a first axis corresponding to the polar axis of the terrestrial globe, and the circle being mounted on the support
  • the duration of the day is the time included, each day, between the moment when the upper limb of the Sun appears to the east above the horizon, at sunrise, until its disappearance to the west below of the horizon, at sunset. Whatever the time, there is always half of the surface of the globe which is illuminated by the Sun, and another half which is in the shadow.
  • the term terrestrial terminator is the line of demarcation between the part of the Earth which is illuminated and that which is in the shadow.
  • the terrestrial terminator is a large circle that surrounds the globe. This large circle extends in a plane perpendicular to the plane of the earth's orbit around the sun (called the plane of the ecliptic). We can still note that the center of the Earth is on the line of intersection between these two planes.
  • the length of the day varies throughout the year and depends on the latitude. This variation is caused by the inclination of the axis of rotation of the Earth on itself with respect to the plane of the ecliptic. This inclination corresponds by definition to the latitude of the tropics which is ⁇ 23 ° 27 '.
  • the duration of the day is shortest during the December solstice in the northern hemisphere, and June in the southern hemisphere. At the equinoxes, the duration of the day is equal to that of the night on the whole Earth.
  • timepieces arranged to indicate the current position of the limit between day and night and which correspond to the definition given in the preamble above. These include descriptions in patent documents EP 2,911,013 , EP 2 977 832 and EP 3,007,012 in the name of the plaintiff. The use and design of these timepieces, however, present a number of difficulties.
  • these timepieces comprise an annual cam which has a profile representative of the inclination of the Sun relative to the equatorial plane and which is intended to be rotated by the movement at the rate of one revolution per year.
  • a disadvantage of these timepieces is that it can be problematic to return the annual cam to the exact position after an indefinite stop time of the timepiece.
  • An object of the present invention is to overcome the aforementioned drawbacks of the prior art.
  • the invention achieves this goal by providing a watch movement according to the appended claim 1.
  • the timepiece comprises a calendar mechanism arranged to be driven via the hours mobile and which comprises means for displaying the date and means to display the month.
  • the timepiece also includes a third kinematic chain that connects the hours mobile to the annual cam via means for displaying the month.
  • the calendar mechanism is driven by the hours motive. Under these conditions, when the wearer of the timepiece changes the indication of the time, for example to correct it, the correction of the time automatically causes the correction of the calendar mechanism and the annual cam.
  • the third kinematic chain has either a transmission ratio of 1/744 th (in the case where the mobile hours is arranged to be driven by the timer at the speed of a lap in 12 hours), a transmission ratio of 1/372 th (in the case where the mobile hours is arranged to be driven by the timer at the rate of one revolution in 24 hours).
  • a simple calendar is a calendar mechanism for which every month has 31 days. In a calendar of this type, it is necessary at the end of months not having 31 days, manually advance the needle or the date disk, to update it. As for the change of the indication of the name of the month, it can be done automatically each time the indication of the date passes from the 31st date to the date 1. The man of the trade will tend to consider that if the annual cam n is not driven by through the means to display the date, the difference between the real time and the current position of the terrestrial terminator on the globe will gradually increase. However, if, for example, the date is pushed forward at the end of the months that do not have 31 days using the time setting, this date setting operation is not likely to de-synchronize the calendar and the annual cam. .
  • the watch movement comprises a summer / winter correction mechanism manually operable to switch from summer time to winter time, or vice versa, by rotating the mobile hours of stepping forward or backward regardless of the clockwork.
  • the manually operable mechanism is arranged to rotate the mobile hours without this also affects the indication of the position of the terrestrial terminator on the sphere.
