Claims

[Scope of utility model registration request]

It has a calendar function that counts clock signals and displays the current time as well as the current month and day, and a alarm function that issues an alarm when the current month and day reaches a preset month and day. An electronic watch with a dial alarm whose main part is a semiconductor integrated circuit and which has a plurality of switches outside the integrated circuit for adjusting the current time and current month and day. A plurality of digital switches whose respective output terminals of the same bit are commonly connected to a plurality of input terminals of the integrated circuit to which the plurality of switches are connected and each of which is set with a numerical value of the month and day, and a plurality of digital switches inside the integrated circuit. A control signal generating circuit is provided in the digital switch and generates a control signal for sequentially reading out the numerical values of the set month and day of each of the plurality of digital switches, and a control signal for subsequently operating the plurality of switches. Electronic clock with alarm.
