A watch has a dial with numerals 1 through 12 circumferentially distributed thereon in a random sequence. The current time is indicated by the watch hands notwithstanding this random sequence of numerals, together with a digital display of the current time. The minute hand makes an abrupt large angular movement every five minutes to the relevant position indicating the minute of current time, while the hour hand makes an abrupt large movement for every hour to the relevant position indicating the hour of current time. When the minute hand reaches the position of numeral 12, the hour hand abruptly moves through a large angular distance to indicate the current hour. Drivers rotate the minute and watch hands in accordance with a predetermined stored program.
