发明名称 Electronic wristwatch
摘要 An electronic wristwatch having calculator circuitry operated by the time standard signals utilized to operate the timekeeping circuitry is provided. The electronic wristwatch includes a timing pulse generating circuit for producing a plurality of signals. Timekeeping circuitry is coupled to the timing pulse time standard signals produced thereby, for producing a plurality of timekeeping signals representive of actual time in response to at least one of the time standard signals being applied thereto. A digital display is provided for displaying actual time in response to at least some of the plurality of timekeeping signals being applied thereto. Calculator circuitry is provided for producing calculation signals representative of numerical information or a calculating function in response to receiving at least two of the time standard signals produced by the timing pulse generator means, the digital display being adapted to display the numerical information and calculating function in response to the calculating signals produced by the calculating circuitry being applied thereto.
