FIELD: physics.
SUBSTANCE: clock comprises the first window to display readings of tens for date from a number of the first sequence of readings born by the first movable facility of display on its surface, the second window for display of unit readings for date from a number of readings sequence born by the second movable facility of display on its surface, at least one drive connected to movable display facilities, for their rotation in pitched order to display the reading selected from a number of specified sequence. At the same time, according to invention, for at least one of pitch positions of the first display facility, one additional reading, independent on tens for date is reflected simultaneously in the same window.
EFFECT: development of clock with information windows that display various information with no detriment to its readability.
