ABSTRACT:
In an analog type of timepiece equipped with an alarm, an alarm time coincidence detection mechanism and a zero seconds detection mechanism are provided whereby switch contacts are closed when alarm time coincidence and zero seconds are detected respectively. A logical product is formed by combining signals from said switch contacts such that an operating signal to actuate an alarm device is produced with a high degree of accuracy. A memory circuit is incorporated to eliminate the effects of imperfect switch contact.
