<p>The timepiece has a circular cam (11) with a section presenting two bends, whose respective distances from a swivel pin of a mobile (9) vary continuously. The bends have ends (11a, 11b) located on a diameter of the mobile to communicate continuous oscillation to a cam follower (12). An index or hand is integrated to a pinion (13) and mounted opposite to a moon cycle scale centered on an axis of the pinion, where an angular extension of the scale corresponds to an amplitude of the oscillation of the pinion connected with a toothed sector (12b) and to a semi period of a moon cycle.</p> |
