Claims (1)

[Scope of utility model registration request] An oscillator circuit that generates a reference signal for a watch, a frequency divider circuit that divides the frequency of the reference signal, a temperature information generation circuit that measures the temperature inside the watch and outputs a temperature information value in binary, and a temperature information generation circuit that measures the temperature information value in a binary number. A pulse number conversion circuit that converts the number of pulses into a number of pulses, a counter that counts the number of pulses, a decoder connected to the output of the counter, and a pulse number that is output from the decoder when the counter counts the number of pulses. An electronic timepiece with a temperature compensation function, comprising an interrupt circuit that interrupts an output from the oscillation circuit or a frequency dividing stage constituting the frequency dividing circuit.
