Claims (1)

[Scope of Claim for Utility Model Registration] A master clock that measures time, a device clock that displays the time in conjunction with the master clock, and regular time detection that detects when the time measured by the master clock is on time. and a time signal device that performs a time reporting operation in response to a detection signal from the regular time detector, wherein the time signal from the master clock causes the regular time signal to be generated from the regular time detector. an on-time detector that detects a time before the scheduled time; an alarm sensor that starts an operation to detect the external environment in response to a detection signal from the on-time detector; a timer that starts operating and generates an output signal at least twice before a detection signal is generated from the regular detector; and a first gate that allows the output signal from the timer to pass only when a detection signal is generated from the alarm sensor. , an alarm device that performs an alarm operation for a certain period of time from the time when an output signal from the first gate is generated; and a detection signal from the fixed time detector is input to the time alarm device in response to the output signal from the first gate. An alarm device for a watch, comprising: a second gate for preventing the alarm from occurring.
