Abstract
An analog universal watch has an area dial 4 showing different areas of the world attached to an area dial spindle 10 and an area dial wheel 11 linked to a timepiece drive mechanism through a minute wheel 15. A pawl fastened to an hour wheel 17 engages with a ratchet wheel 12 fastened to the area dial spindle 10 so that an hour hand spindle 16 is driven indirectly. Provisions are made to permit correcting the area dial spindle 10 by means of a hand setting stem through the minute wheel 15, along with the independent correction of the hour wheel 17 by means of the hour hand correcting wheel 25 that engages with and releases the hand setting stem. Thus, the timepiece permits not only the ordinary correction of the pointers but also the setting of the hour hand alone to the local time of the desired area.
