PURPOSE:To enable the abnormality of a health condition to be simply reported, by detecting factors representing respective health conditions of a body, such as the pulse, the bodily temperature and the like, and displaying them on the time display part in a change-over manner as well as generating an alarm when a detected value reaches a critical value. CONSTITUTION:Such detectors as a pulse detector 7, a bodily temperature detector 8 and the like are provided on the back side of a wrist watch. Moreover, according to need, a breathing number detector and the like are connected with the electronic wrist watch. The respective pulses detected by the detectors 7 and 8 are supplied through a reception part 9 to a frequency dividing circuit 10, where they are frequency-divided so that each number of the detected pulses per given unit time is displayed, and supplied to a display circuit 11. Memory circuits 13 and 14 store the critical numerical values of the pulse and the bodily temperature detected by the detectors 7 and 8 and supply them to a coincidence discriminating circuit 15. If the detected value reaches a previously set critical numerical value, the display is changed over to that of the critical numerical value. At the same time, an alarm is sounded from a speaker 21.
