Patent ID: 7440359

Claim:
A timepiece including a timepiece movement associated with an analogue display including at least one mobile indicator, said timepiece movement including at least one motor and control means delivering pulses for controlling said motor, said motor being provided for driving said mobile indicator via a gear reduction train, said train including an intermediate wheel between the motor and a second wheel secured to the mobile indicator, the gear reduction train being provided for driving the intermediate wheel through a constant angle upon each revolution completed by the motor, the timepiece further including checking means for determining whether the real movement of the mobile indicator corresponds to the signal delivered by the control means, and correction means connected to the checking means and provided for controlling the motor so as to correct the position of the mobile indicator, the timepiece being wherein the checking means include means for detecting at least one angular reference position of the intermediate wheel, said detection means being provided for supplying a signal having a first value when the intermediate wheel is occupying said angular reference position and for supplying a signal having a second value, different from the first, when the intermediate wheel is occupying a second angular position, the timepiece being further wherein the checking means include first means for counting the pulses delivered by the control means, and identification and comparison means for determining, on the basis of the signal supplied by the detection means, at least one per revolution of the intermediate wheel, whether the real position of the intermediate wheel actually corresponds to the state of the first counting means.
