Set the preliminary position for the date, and the hour and minute hands.
The preliminary position of the date is the “1st”.
The preliminary positions of the hour and minute hands are “0:00 AM”.
When the preliminary positions are incorrect, the correct time and date cannot be displayed even if the watch receives radio signals.
In such a case, by correcting the preliminary positions, the loss or gain of the time or date can be corrected.
When the numerical number of the date is not located at the center of the window, it can be corrected by the same procedures as mentioned above.
To correct the preliminary positions, perform the following operation.
In procedures 1 to 5, when no operation is conducted after the date numeral and small seconds hand stop, and the watch has no movement of the date or the seconds hand for 20 seconds or longer, it automatically displays the time again. When it is in the middle of operation, re-attempt the operation from procedure 1.

Setting the Preliminary Position of the Stopwatch Second and Minute Hands
If any of the stopwatch hands do not return to the 0 minute 0 second position when the stopwatch is reset, the preliminary hand position may be misaligned.
The preliminary position of the stopwatch second hand is the 0-second position, and that of the minute hand is the 0-minute position.
Adjusting the hands to the preliminary position will ensure that stopwatch measurements are correct.
