Abstract

A twenty-four hour digital display in which the numerals for the display are carried by a 1-hour barrel and a 10-hour barrel which are stepped by a stepping device. A steppable visor driven in steps by the 10-hour barrel covers part of the time the 1-hour barrel which has a function of the time display. The visor itself carries numerals for indicating single-digit hours. The stepping device includes a gearing and a shaft which serves simultaneously as a locking device for the two barrels.
