摘要： The time-keeping apparatus comprises a timer unit capable of emitting time signals and an indicating unit having timeindicator such as hour and minute hands. The timer unit emits a time signal wave such as a supersonic wave at constant intervals by means of a synchronous motor serving as the reference of time. Communication between the timer unit and the time-indicating unit is effected by a wireless system. A signal receiver incorporated in the time-indicating unit is rendered to the condition of being able to receive a time signal a little before this signal wave is emitted to function so that, upon receipt of same, it drives a time-indicator actuating mechanism. Thereafter, the receiver is relieved of this condition. The time-indicator actuating mechanism thus driven causes the hands to be displaced in their positions in accurate agreement with the advancement of time.

摘要： An autonomous radio timepiece (11) with a magnetic antenna (14) located in the vicinity of a electromechanical transducer (25) for driving a time display (19), in order to obtain a radio timepiece with a small volume and operable in a compact manner. To avoid electromagnetic interference with the antenna inlet of a tuned radio-frequency receiver (12), the transducer (25) is deactivated while the receiver (12) is actuated for the reception and coding of an absolute time information (15) transmitted by radio. A subsequent recovery of the transducer drive pulses (42) for autonomous time keeping corrects the display (19). However, a transducer (25.1) may remain in uninterrupted operation if it is located relative to the antenna coil (33) with the relative position of its core (34) in a manner such that components of the stray current or electro magnetic field (39) exiting from the frontal side of the transducer field coil (39) in a fan-like manner passes through the antenna coil (33) in opposite directions, so that the two components (39a, 39b) of the stray current offset or cancel each other out. In a two-motor radio timepiece mechanism, the second transducer (25.2), the stator stray current (39.2) thereof cannot be compensated in the antenna coil (33), remains deactivated during the operation of the receiver and is assigned to the display means (19) with the slowest advancing action, for example, the hour hand in case of a separate drive of the minute and possibly the seconds hand.
