摘要: An electronic timepiece is provided with an alarm and means coupling a sounding unit to circuit generating sonic signal. The first electrode (6) of the (5) mechanically electrically fixed metallized decoration (4) set under glass (3). Two conductive members (12) are arranged pass through dial then be elastically supported, against second (7) in order connect said terminals (10) signal circuit. arrangement facilitates encasing thus realizes increased productivity.
