The present invention relates to a radio clockwork mechanism which includes a movable hour hand and a mechanism for determining which hour the hour hand is currently indicating. That determining mechanism comprises hour-contact arches, a scanning mechanism, and a querying mechanism. The hour-contact arches are assigned to respective hours and are spaced apart a circular path. The scanning mechanism includes an hour-scanning device which is movable synchronously with the hour hand for sequentially scanning the hour-contact arches and giving a currently scanned hour-contact arch and an electrical potential different from all other hour-contact arches. The querying mechanism queries the hour-contact arches for determining which has the different electrical potential. |
