PROBLEM TO BE SOLVED: To provide an electronic time piece capable of exchanging power supply or signal between modules without restricting small-sizing or thinning, regardless that time indication function and additional functions are constituted of individual modules and, of improving the reliability of electric connection part between modules. SOLUTION: A module 20 for time indication bearing the main function of an electronic time piece 10 is provided with an external negative lead terminal 3 supplying power from containing battery 2 to additional module 8 and an external positive lead terminal 4d. As the power source is common for the two modules, the electronic time piece 10 can be small-sized and thinned. Furthermore, in the case the specification of the additional module 8 is changed, contact points are formed at the positions corresponding to the terminals 3 and 4d in the additional module 8 side, design change of the module 20 for time indication is not necessary. |
