Abstract
An electronic watch is set to the proper time by correction of the content of counters of the watch through the actuation of one or both of two switches. The actuation of the first one of the switches selects whether the content of the counters is to be incremented or decremented at a first speed. The subsequent actuation of the other switch performs the correction at a second higher speed in the sense selected by actuation of the first switch.
