Abstract

A radio-controlled timepiece comprises an antenna in the form of a core on which a coil is mounted. The core includes a hole spaced from the coil and defining an axis oriented perpendicular to the coil axis. A printed circuit board is disposed in the hole such that electrically conductive tracks thereof are arranged in a plane lying within a center plane of the core.
