• This mechanical watch has a planetarium that permanently shows the positions, seen from the north pole of the ecliptic, the Sun, the Moon and five planets other than the Earth, relative to the latter and the zodiac. But these positions do not correspond to the reality of the solar system at least because of the non-respect of the dimensions of the orbits and therefore have no scientific character.

• At least one second image screen 61 collecting user-readable indications of the equipment representative of the first and second parameters 11, 12 determined by the electronic processing unit and / or representative of the local horizontal coordinates 13 of the Sun established by the electronic processing unit and / or representative of the local horizontal coordinates 19 of the bodies other than the Sun established by the electronic processing unit and / or representative of the astronomical information established by the electronic processing unit,
• a third image-screen representing, for the current year, the evolution over the days of the relative positions of the Sun, the Moon, the nodes of the lunar orbit and the planets visible to the naked eye, makes it possible to identify the most suitable moments for observing the planets according to their elongation; the horizon and the direction of the meridian are figured,
• a fourth image-screen representative of the real appearance and position of the Moon allows to display in its real appearance and position a stylized Moon, with its illuminated part, its terminator, its seas and its main craters, possibly the ashy light, the shadow of the Earth in case of eclipse of the Moon, its height,
• the image screens 60 and 61 are more fully detailed below.
• the first image-screen 60 corresponds in particular to the horizontal projection of a portion of the celestial sphere on a vertical cylinder of nadirzenith axis.
• the image screen 60 thus gives the representations of the time dial in their concrete visual appearance.
• this image-screen can be the three-dimensional representation of half of the visible half-sphere centered on the plane of the meridian.
• the second image-screen 61 thus gives the encryption of numerous parameters relating to celestial phenomena, among the following information which can be displayed after determination by the electronic processing unit: the appearance of the Sun and the Moon with their current diameters and the terminator for the moon if it is raised,
• the difference between the legal time and the solar time to set a sundial, - the difference between the UTC time and the solar time, to adjust a map of the starry sky, the azimuth, the height, the sunrise and sunset (each defined by its time and its azimuth), the passage of the Sun to the meridian of the place (defined by its time and its height),
