<P>PROBLEM TO BE SOLVED: To provide a radio correction watch for improved workability in manufacture as well as productivity at a lower cost for easy operation. <P>SOLUTION: If a user pulls a crown 212 while a second hand points 0 o'clock to change a display time to such state as 0 o'clock is pointed as an initial state, and then presses in the crown 212, an input operation recognizing means 460 recognizes it as a prescribed operation. A pointer position data initializing circuit 447 resets the counter value of a pointer position counter 446 to the initial value of 0 o'clock 0 minute 0 second. A reception means receives a long frequency standard radio to obtain a time code. Based on the reference signal outputted from a dividing circuit 444 at the oscillation signal from a quartz oscillation circuit 443, a time data comparing circuit 448 counts a current time from the time code, and compares it with the initial value to recognize a difference from the count value. Based on the difference, a pulse control circuit 445 makes correction for a current time. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
