Abstract: A solar-powered LCD device, e.g., for a clock, includes a solar cell arrangement and a liquid crystal display. The solar cell arrangement includes an at least partially transparent carrier and at least one solar cell provided with at least one at least partially transparent contact, at least one first polarizer, a first at least partially transparent carrier, a first at least partially transparent contact, a liquid crystal, a second transparent contact, a second transparent carrier, a second polarizer, and a reflector in a stacked arrangement. The carrier of the solar cell arrangement is one of the carriers of the liquid crystal display.

Abstract: A radio-controlled wrist watch includes a watch case in which are housed a brass dial and a signal-receiving antenna, such as a lamellar antenna. The dial defines a center axis, and the antenna is spaced at an axial distance from the dial of more than 0.5 mm, e.g., 1 to 4 mm, more preferably 1 to 3 mm.

Abstract: A wristwatch is converted into an emergency call device by unscrewing a rear cover from the back of the wristwatch housing and screwing in a transmitter housing that carries a signal-emitting mechanism.

Abstract: A radio-controlled wristwatch includes a casing. A central portion of the casing disposed generally centrally with reference to a longitudinal center axis of the casing is formed of metal at least on the exterior thereof. An antenna core is disposed within a chamber defined by the casing. The antenna core lies on a plane oriented transversely with respect to the longitudinal axis. A spacer ring is disposed in the chamber between the central portion and the antenna core, the spacer ring formed of electrically non-conductive material.
