A portable time piece having a casing for supporting a watch movement therein. A dial face is also disposed in said housing with a time indicator visible from a top side of the dial face whereby to display time. The time piece is characterized by a light diffusing member located above the dial face and extending in a predetermined circumferential area thereof. At least one light source is associated with the light diffusing member so that light is transmitted along and out of the member to illuminate at least the portion of the dial face, and radiate light outwardly of the top side of the casing. A light source within the casing supplies electrical power to the light source.
