Abstract

A day and date correcting device in a timepiece having a day-star wheel and an annular date ring mounted concentrically of the day-star wheel. A correcting lever is positioned between the day-star wheel and the date ring, and the correcting lever has a first protrusion for engaging the day-star wheel to advance the same, and a second protrusion opposite the date ring for engaging the date ring to advance the same. A tab extends from the correcting lever. A correcting wheel having a peripheral tooth is mounted for rotation adjacent the tab and is positioned to engage the tab upon rotation of the correcting wheel to slide the correcting lever to a day correcting position and a date correcting position according to the direction of rotation of the correcting wheel for effecting day and date correction. The correcting wheel is manually rotatable. A resilient element restores the correcting lever to a neutral position intermediate the day correcting and the date correcting positions, after the correcting wheel has been rotated to advance the correcting lever to one of these positions and rotated further to disengage and clear the tab.
