TIMEPIECE INCLUDING MEANS FOR DETERMINING THE ANGULAR POSITION OF AN ANALOGUE INDICATOR OF THE TIMEPIECE

The timepiece has checking unit with a reed contactor (22) for detecting an angular reference position of an intermediate wheel (9), where the contactor supplies a signal with a value when the wheel is occupying the position. The contactor supplies a signal with value different from the former value...

Zusammenfassung:	The timepiece has checking unit with a reed contactor (22) for detecting an angular reference position of an intermediate wheel (9), where the contactor supplies a signal with a value when the wheel is occupying the position. The contactor supplies a signal with value different from the former value when the wheel is occupying another position. An identification unit (32) and a comparison unit (33) determines per revolution of the wheel on the basis of the signal supplied by the contactor whether the real position of the wheel actually corresponds to the state of a counting unit.
