<P>PROBLEM TO BE SOLVED: To provide a radio controlled watch capable of saving power. <P>SOLUTION: After time is corrected by the operation of a crown 710, an initial reception processing for acquiring time information including minute information and hour information is made for correcting time, and passage time after reception is clocked. Based on timing schedule information, reception is made periodically. Specific condition timing information is selected from a reception schedule storage means 433 by a schedule information selection means 432 corresponding to the passage time in reception. Based on the time information of condition timing information, reception is started at time earlier than the initial setting time for executing normal reception. As the passage time becomes longer, reception timing becomes earlier, and the work time length for reception is extended. The power consumption for acquiring the minimum time information required for time correction can be minimized to save power. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
