ABSTRACT:
A watch dial face is provided with liquid crystal numerals which, in the case of a regular watch face, is located at the twelve positions on the face of the watch. The liquid crystal at these positions range to indicated temperature from minus ten degrees Fahrenheit (-10.degree. F.) to one hundred degrees Fahrenheit (100.degree. F.), and correspond to the numerical value at each position, e.g., one o'clock=10.degree. F.
Liquid crystals serve a DUAL purpose. Markings on the face of a wristwatch or clock, using liquid crystals, will indicate the time by observing the hour and minute hands. Markings on the face of a wristwatch or clock, using liquid crystals, will indicate the temperature by observing color change to any one of the 12 liquid crystal markings. The markings, using liquid crystals, may be of any shape, small or large such as circles, rectangles, squares, dots, and so on.
