Claims

[Scope of claim for utility model registration] The reference frequency signal is counted, and at least the year, month,
A timekeeping means for obtaining the current time including the day; a data storage means for storing a plurality of date data including at least a year, a month, and a day; the current time obtained by the timekeeping means and date data stored in the data storage means; a coincidence detecting means for detecting coincidence of at least a month and a day with the date and time; a comparison determining means for comparing and determining the current year obtained by the timekeeping means and the year of the date data stored in the data storage means; When the match detecting means detects a match and the comparing and determining means determines that the year of the date data is equal to or earlier than the current year obtained by the clocking means, the match is detected. What is claimed is: 1. An electronic watch with a date alarm function, characterized in that it is equipped with a notification means for notifying.
