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.
