<P>PROBLEM TO BE SOLVED: To provide a radio-controlled wrist watch on which a metal casing can be used. <P>SOLUTION: In this wrist watch, at least a central part 13 of the casing is to be designed as a thin solid core or a coated conductive ring shape. Inside the central part 13, a spacer ring 20 made of nonconductive material is installed, and the ring 20 holds a wrist watch mechanism 22 equipped with circumferential antenna core 29. The antenna core 29 is located sideways between two disks made of nonconductive material, specifically between a glass 16 and the casing bottom 18, within cross-sectional height limits of the metal central part 13 radially at a certain interval with respect to the central part 13. The bottom section 16, preferably, consists of a glass plate. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
