An electronic timepiece circuit including a data memory for storing time information and display information, and an operating circuit which renews the data stored in the data memory circuit. A program memory circuit stores a sequential program for determining generation of control signals supplied to the data memory circuit and the operating circuit. Two different command data systems are stored in the program memory circuit. One command data system consists of controlling commands which carry out time counting, time setting and display functions, and for pointing addresses in the data memory circuit. The other command data system consists of commands for judging conditions, for pointing addresses of the data memory and for pointing the jump address of the programs stored in the program memory circuit.
