Abstract

PURPOSE:To simplify a multi-function watch circuit by using a push button contact for switching a key circuit and a display circuit. CONSTITUTION:When a push button is operated, the lamp line 23 of a display lamp 28 and the key line 21 of an IC 26 are connected with an earth line 22 to make both a world time display key circuit and a display circuit. Thus, it is possible to make the multiple functions of a watch for displaying the world time and areas with the use of a simple circuit requiring no spacing circuit in the IC 26.
