Abstract: A wristwatch having a switching crown to effectuate an electrical switch function. The switching crown comprises a crown element constructed from electrically conductive material. The crown is in contact with a first conductor element connected to one side of a battery. A second conductor element extends in a portion of the crown and electrically isolated therefrom. A peripheral inner end portion of the crown is disposed closely spaced to the second conductor element. The peripheral inner end portion is placed in contact with the second conductor element by maintaining a side pressure on the crown element to effectuate a switch closure.

Abstract: A light diffusing ring for positioning in a wristwatch about the circumference of a time display face thereof to illuminate the face. The ring is constructed of light transmitting material. The ring defines a top and a bottom wall, parallel to one another and an inner side wall. An elongated cavity is formed in an outer side wall of the ring and extends at least in one quarter of the circumference of the ring. The cavity has a cross-section dimension to receive at least two lamps therein and spaced from one another.

Abstract: An electrical conductive circuit for use in a wristwatch and wherein the circuit comprises an elongated flat electrically conductive band formed from a conductive strip having opposed electrical insulating layers. The band also has a component attachment region and a pair of battery terminals. The band is also formed as a flexible band which is adaptable to be configured to fit in a slot area of a wristwatch.

Abstract: 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.
