Abstract

In an analog timepiece having calendar displays for day and date, a transducer operating independently of the hand driving transducer, feeds, that is, updates the calendar wheels automatically on a daily basis. Synchronization of the daily day and date changes is provided by a twenty-four hour wheel cooperating with the time-keeping mechanism. For setting the calendar displays, turning the stem in one direction polarizes a magnet and advances the day wheel, while turning the stem in the other direction reverses the polarity of the magnet and advances the date dial until desired settings are accomplished. The date advancing transducer can be automatically actuated for end of the month date adjustments.
