Electronic watch

Abstract

Abstract PURPOSE:To also facilitate the comparison of max. atmospheric temp. and min. atmospheric tem., by a method wherein a temp. is displayed by using the hand of an analogue watch having an optical display element used therein to make the watch multifunctional. CONSTITUTION:At the time of a clock mode, an hour hand is displayed when one among an hr display element group 2 is lighted and the hr display element group 2 and a min display element group 3 are lighted at the same angle from the center of a watch main body 1 while a sec display element group 4 is lighted and put out to enable the reading of a sec. When the clock mode is changed over to a thermometer mode by manipulating a crown 6, a temp. graduations display element group 5 is lighted and the temp. at this time is displayed by lighting the hr display element group 2 and the min display element group 3 at the same angle from the center of the clock main body 1 while the max. atmospheric temp. and the min. atmospheric temp. of that day are shown by lighting the min display element group 3 and the sec display element group 4 at the same angle. By this method, the atmospheric temp. at the time, the max. atmospheric temp. and the min. atomospheric temp. of the day are known on sight and, even if the atmospheric temp. at the time is coincided with the max. atmospheric temp. or the min atmospheric temp. of the day, they can discriminated immediately.
