Abstract
An electrically driven timepiece is provided with a single user-actuated h button for controlling a modulo-three counter, the counter being utilized to control display advancing pulses derived from an oscillator and frequency divider. In a first state, the counter controls the display advancing pulses to advance the display at a normal rate. In a second state, the counter controls the display advancing pulses to advance the display at a rapid rate to effect a time correction. In a third state, the counter blocks all advancing pulses whereby the display remains constant. This enables the user to restart the advancement of the display at a precise desired instant. In an alternative embodiment, means are provided within the timepiece for automatically advancing the counter from the second to the third state when the display is advanced to a reference position such as the zero seconds position.
