Abstract: A timepiece includes a date indicator with inner teeth moving angularly by one step per day. An indication control star meshes with the inner teeth of the indicator. A pinion that is integral and coaxial with the star drives an indicator wheel on which an indication arbor is centrally disposed. The rotary indicating structure is driven by the date indicator through the indication arbor and is intended to indicate cyclic parameters such as the date, the phase of the moon, the user's "cash balance," etc. Various types of indication, all controlled by the date indicator, make it possible to produce a wide range of watches of simple design with different display combinations.

Abstract: A horological piece includes a display (10) comprising a recurring cycle indicator (13) driven by an independent motor (11) and having a supplementary display position (14) at which a sign representative of the state of charge of an energy source controlling the display, is provided. The horological piece further includes a detection circuit (2, 16) adapted to, firstly, during the detection of a predetermined level of charge of the energy source, control the display so that the recurring cycle indicator is moved the required number of steps to display the representative sign and, secondly, jump the supplementary position during the normal operation of the horological piece.
