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° F.) to one hundred degrees Fahrenheit (100° F.), and correspond to the numerical value at each position, e.g., one o'clock=10° 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
Combined time and ambient temperature indicating device whereby the temperature, in centrigrade and fahrenheit degrees, for each hour is displayed in visual association with the indication of the hour or part thereof comprising a casing having enclosed therein a clock mechanism and having a watch display face on which hourly time indicator factors are located in a circular visual pattern and in relation to means driven by the clock mechanism and independent liquid crystal temperature indicators placed on said display face at each time indicator factor so that for each hour position the surrounding ambient temperature will be displayed whereby a visual glance at the face to determine the time will enable a person to determine the temperature at such time.
Claim 2
Dependent Claim
121 words
Combined time and ambient temperature indicating device whereby the temperature, in centrigrade and fahrenheit degrees, for each hour is displayed in visual association with the indication of the hour or part thereof comprising a casing having enclosed therein a clock mechanism and having a watch display face on which hourly time indicator factors are located in a circular visual pattern and in relation to means driven by the clock mechanism and independent liquid crystal temperature indicators placed on said display face at each time indicator factor so that for each hour position the surrounding ambient temperature will be displayed whereby a visual glance at the face to determine the time will enable a person to determine the temperature at such time.
Claim 3
Dependent Claim
12 words
The invention of claim 1 wherein the device is a wall clock.
Claim 4
Dependent Claim
11 words
