An alarm clock includes a time indicator, a first alarm for sounding a first alarm at a preset time, a manual rotary bezel provided rotatable relative to the time indicator outside same for setting a time elapsing from the alarm time, and a second alarm for sounding a second alarm when the time set by the rotary bezel has elapsed since the preset time. After the first alarm is sounded at the alarm time, and after the time set by the rotary bezel has elapsed, the second alarm is sounded. The time interval after which the second alarm is sounded is set by a simple operation and two-staged sounding ensures proper awakening of the sleeper.
