Definitions

  • the present invention relates to a device for displaying legal time as well as sunrise time and/or sunset time, comprising a first legal time index arranged to indicate the legal time, a display member for the time of sunrise and/or sunset, a second index arranged to indicate the time of sunrise and/or a third index arranged to indicate the time of sunset sun on the sunrise and/or sunset time display.
  • the present invention also relates to a timepiece comprising such a display device.
  • Such a type of display device is used in a timepiece to traditionally display the legal time on a main 12-hour dial by means of an hour hand as well as the rising and setting times of the sun on two dials or angular sectors graduated by means of two respective hands or indexes.
  • These dials or angular sectors used to read sunrise and sunset times are generally distributed across the main dial with other displays, each hand or index having its own axis of rotation.
  • These additional dials or angular sectors have the disadvantage of weighing down and loading the main dial with information, making it difficult to read the time. They can be positioned on the back of the timepiece to free up space on the main dial. But as a result, they will not be visible to the user when he wears the timepiece on his wrist.
  • request CH 712 493 proposes a mechanism making it possible to modify time information linked to an astronomical phenomenon, such as the time of sunrise or sunset, according to summer time and winter time and/or a longitude or a time zone.
  • Said mechanism comprises a bistable control operated manually and arranged to act only on an indicator of the time of sunrise or sunset, also managed by a wheel controlled by astronomical calculation mechanisms, by causing a movement of a time of said sunrise or sunset time indicator during the summer/winter time change, as well as on a control indicator showing the two stable summer/winter positions of said control.
  • This document does not give any information on the correction of the legal time at the time of the summer/winter time change when the bistable command is used.
  • the patent document CH 693 599 A5 discloses a timepiece comprising a disc representing a terrestrial hemisphere centered on a pole.

  • the timepiece also includes a line which connects the 6 o'clock and 18 o'clock graduations of the hour ring and which demarcates the nocturnal part of the daytime part of the Earth.
  • the patent document EP 3 339 971 A1 discloses a timepiece comprising a sphere reproducing the terrestrial globe, a support, and a circle mounted on the support concentrically with the sphere and arranged to indicate the position of the terrestrial terminator.
  • the sphere is driven at the rate of one revolution in 24 hours around an axis corresponding to the polar axis of the terrestrial globe, and the circle is arranged to pivot concentrically with the sphere around an axis perpendicular to the axis of rotation of the terrestrial globe.
