Abstract
A device for controlling or correcting the readout of the day of the week or date for an analog watch, comprising a crown cogged on the inside and integral with a date or day disk, a bi-directional drive motor and a drive wheel coupled to the drive motor, the drive wheel having two opposite spring-loaded clicks and an arcuate slot in which a fixed stud is engaged, the stud cooperating with the edges of the slot to limit the travel of the drive wheel. The drive mechanism of the date or day disk can thus be recentered automatically after the watch has stopped while simultaneously compensating the rated steps of the motor.
