Abstract

An improvement in a date indexing device for an analog watch using manual indexing of a date ring with a push button. The indexing member indexes the date ring with a pawl guided onto the toothed rim of the date while one of the driving gear elements for the date ring is disengaged by moving an elastically yieldable support for the gear element.
