PURPOSE:To make it possible to sense a specified time without being noticed by persons other than a watch carrying person with a simple, compact, thin constitution by providing a stimulus generating circuit, which imparts electric stimulus that can be sensed with a human body, in the main body of the watch, and operating the circuit at a specified time. CONSTITUTION:A stimulus generating circuit 1, which imparts a low frequency from a low-frequency oscillator as electric stimulus, is constituted. That is to say, a pair of electrodes 5 and 6 are arranged at the contact surface of the main body of a wrist watch (fixing-band part) with the skin in this circuit 1. A low-frequency pulse oscillator 7, which imparts the low frequency across the electrodes 5 and 6, is provided in the main body of the watch. Fine adjustment can be performed with an output control part 8 in the main body of the watch in this constitution. As to a control circuit 3 for controlling the operating time of the oscillator 7, an alarm time setting mechanism 9 and a timer mechanism 10 are provided. When the alarm time is set with the mechanism 9 (watch function button), the oscillator 7 is operated at the specified time with the mechanism 10, and the low-frequency pulse are outputted across the electrodes 5 and 6 through the control part 8. The stimulus is imparted to the skin, and the watch carrying person senses the specified time. |
