Abstract: An autonomous radio timepiece comprises a casing and a bracelet attached thereto. The casing includes an operating circuit, while the bracelet carries a flexible antenna. The antenna can be removed from the bracelet in the event that the bracelet is worn and must be discarded. The antenna carries a plug-in type connector at one end which is adapted to make a tight sealing connection with the casing, and is also adapted to electrically connect the antenna with the circuit of the casing. The circuit within the casing includes a receiver which is fixedly tuned as a function of the antenna inductivity of a foil core to the time message transmitter. Also provided is a variable automatic supplemental tuner to compensate for bending of the bracelet while the receiver is actuated. The antenna comprises a foil of an insulting material on which an antenna conductor is printed, along with two shielding conductors extending parallel to the antenna conductor.

Abstract: A watch contains a date indicator ring and a day of week indicator ring. A switching wheel is displaceable selectively into meshing engagement with the indicator rings to effect adjustment thereof. The switching wheel is actuated by a shaft which is axially displaceable between selection and working positions. In its selection position, the shaft can be rotated in either direction to selectively place the switching wheel in one of two preliminary locations corresponding to a date ring adjustment location and a day of week ring adjustment position. By then axially displacing the shaft to its working position, the switching wheel is displaced to a final location to effect the previously selected mode of adjustment. Such adjustment is effected by rotating the shaft in either direction to rotate the respective indicator ring in either direction.
