ABSTRACT:
An alarm signaling time setting member is coupled to a minute indication drum having minute-scale alarm time graduations and an hour indication drum having hour-scale alarm signaling time graduations is intermittently advanced by the minute indication drum. First and second detection members for detecting the alarm signaling time are provided in correspondence to an hour time wheel and a minute time wheel respectively. The first detection member is geared to the second detection member, and the second detection member is geared to the minute indication drum to permit the detection member positions to be continuously set.
