Date Sep. 12, 1986.A watch designed to display, by means of indicators (7 to 10) several astronomical magnitudes. The indicators are driven by means of a planetary gear train (19) which is rotatingly supported by means of a ball bearing (20) within a support ring (11) of the watch. The drive force as well as the time reference are provided by a work (C) simultaneously driving the planet-wheel carrier (21, 22) of the planetary gear train and the gear clusters mounted thereon. Each of said clusters has a reduction ratio depending on the indicator (8 to 10) it is intended to drive.
