Abstract
A wrist watch having an area of user selectable color preferably includes a watch body, watch face, heated surface, power source, and control. The watch body may be circular, square or rectangular in shape. The watch face is preferably covered by a watch crystal and the face color may be changed via thermochromatics or a color plate. A heated surface activates a color change in the thermochromatic watch face and a power source supplies a voltage to power the heating surface. A control allows manual control of the color change and may be located anywhere on the watch body.

7. A watch having an area of user selectable color, comprising:
-
a watch body having a timekeeping mechanism; a variable color thermochromatic liquid crystal watch dial that changes color with temperature changes contained within the watch body, wherein the variable color thermochromatic liquid crystal watch dial is one color at a given temperature and as the watch dial temperature is altered, becomes another color of the visible color spectrum; a surface adjacent the thermocromatic watch dial in thermal contact with the watch dial; a power source having an output for supplying a current to power the surface; and a control for manually controlling the current to selectively heat the surface, whereby the variable color thermochromatic liquid crystal watch face may be controlled to maintain a color for a given period of time. - View Dependent Claims (8, 9, 10)
