Abstract

PURPOSE:To prevent wrist watches used in daily life from being mislaid by a method wherein an electric current circuit is operated to generate an alarm signal at predetermined intervals when the wrist watch is removed from the wrist. CONSTITUTION:An oscillating output from an oscillation circuit 1 utilizing a quartz vibrator is added to a counter circuit 3 via a dividing circuit 2, and the output of the counter circuit 3 is applied to a display circuit 6 via a decoder circuit 4 and a driver circuit 5 so that time is displayed. On the other hand, a thermocouple 7 is attached to a back lid 17 and a glass part 18, whereas the temperature difference between the back lid 17 warmed by the body temperature and the glass 18 is measured at measuring part 8 so that a control circuit 9 is controlled. When a wrist watch is carried, a timer 10 operates at time intervals set by a setting part 11 whereby a buzzer issues an alarm via a buzzer energizing circuit 12. Due to this, an alarm circuit operates when a wrist watch is removed, preventing it from being mislaid.
