Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a radio control correction watch constituted of a case wholly made from metal material so as to secure high appearance quality, as well as excellent receiving sensitivity of the standard frequency transmission even if an antenna device is sealed in the case. SOLUTION: The case which contains the main part of a radio control correction watch is equipped with the annular drum member used as side wall, and the lid member 113 which covers the aperture of the drum member by the side of the back. The storage space for containing the antenna 15 is formed near the lid member 113 in the case. In addition, thin-walled portion 113A in the position corresponding to the antenna 15 is formed in the lid member 113, compared with other portions of this lid member 113. COPYRIGHT: (C)2005,JPO&NCIPI
