Abstract
An electronic alarm timepiece comprises a quartz crystal oscillator, a frequency divider, a display driving means, a display means, an alarm signal shaping means and an alarm means. The alarm signal shaping means is so arranged that a pair of output signals which are opposite in phase are produced with the aid of output signals of the frequency divider for actuating the alarm means, whereby it is possible to provide an alarm signal shaping means in the form of a complementary metal oxide semiconductor (CMOS) integrated circuit having sufficient power to actuate the alarm means without other amplifying circuits.
