Abstract (en)

[origin: EP1475680A1] The device has an axle that is rotatably mounted on a turntable to make a predefined number of turns by lunar month. A transmission mechanism ensures a kinematical link between the axle and a mobile indicator (3) to enable the indicator to make a turn by lunar month with respect to a dial (1). The indicator is rotatably mounted at a point of a rotating support of the transmission mechanism, making two turns by lunar month. The mobile indicator moving behind the dial includes an S-shaped separation line between dark and bright zones seen across a circular aperture of the dial. The indicator includes a rotational axis that passes by a center of symmetry of the separation line. The transmission mechanism includes another rotational axis de-centered with respect to the aperture. The rotating support of the transmission mechanism includes a trajectory passing by a center of the circular aperture of the dial.
