Abstract (en)
[origin: US5023849A] The invention concerns an astronomic timepiece enabling a simple display of the daily value of an astronomic magnitude having an annual cycle. The timepiece comprises a month disc (13), at least a portion of which is visible through an opening (19) provided in the dial (6). The development of the astronomic magnitude is represented in the form of a curve (25) in a frame of reference one coordinate of which indicates the date and the other indicates a value of the astronomic magnitude.
