ABSTRACT:
An electrically driven timepiece has a high frequency oscillator, a frequy divider and a time display capable of displaying at least minutes and seconds wherein correcting and setting of the display is obtained by means of a single user accessible switch capable of assuming at least two positions including a neutral and an active position and a sequential discriminator circuit which includes a plurality of memory devices, a timing chain and a bistable circuit controlled by the switch so that cycles of impulses applied to the switch within predetermined time periods by the user will result in the addition of a unit count to the seconds display or the blocking of the display advance or the driving of the display at a higher than normal rate in accordance with the cycle pattern employed.
