Abstract
In an electronic timepiece equipped with an alarm function, an alarm time memory circuit is provided for setting in an alarm time by actuation of an external control member and another memory circuit is provided into which an advance warning time period can be set and stored. Means are provided for detecting coincidence between the current time and an advance warning time comprising the difference between the memorized alarm time and the advance warning time period, to provide an advance warning signal prior to the actual alarm time. Parallel computation is used to generate said advance warning time, and the advance warning time period can be continuously displayed.
