Preliminary position
When the watch is unable to display the precise time date or day even if it successfully receives
a radio signal with the correct time zone setting, the preliminary position may be misaligned.
The preliminary position may be misaligned due to the following reasons.
・ In the case of having a strong impact: Misalignment of the time and date may occur when dropping or hitting the watch.
・ In the case of a magnetic influence: Misalignment of the time and date may occur when
bringing the watch close to an object which generates magnetism.
→ Example of common magnetic products that may affect watches. P.115
When comparing the state of Misaligned Preliminary Hand Position to that of a weight scale, it is like a scale
which is unable to display the correct weight because its needle is not set to the zero position before weighing.
■ Automatic Hand Position Adjustment Function (Function to automatically
adjust the preliminary position of the hour and minute hands)
The hour, minute, and second hands have an Automatic Hand Position Adjustment Function,
which automatically corrects an incorrect preliminary position.
Automatic Hand Position Adjustment Function activates once a minute for the second hand and
at 12:00 both for the AM and PM for the hour and minute hands.
※ This function works when the preliminary hand position is misaligned due to external factors such as strong impact or magnetic
influence. It does not work to adjust accuracy of the watch or slight deviations which may occur during the manufacturing process.
※ The preliminary position of the hour and minute hands can also be manually adjusted. → Setting the preliminary position of the date P.135
■ Setting the preliminary position of the date and the day
Since the preliminary position of the date and the day is not automatically adjusted, it must be adjusted manually.
→ Setting the preliminary position of the date P.135

How to correct the preliminary positions
■ Setting the preliminary position of the date,
day hand, hour and minute hands
The preliminary position of the date is the 1st.
The preliminary position of the day hand is S. (Sunday)
The preliminary positions of the hour and minute
hands are 0:00 AM.
When the preliminary positions are incorrect, the correct date, day of the week
or time cannot be displayed even if the watch receives radio signals.
In such a case, by correcting the preliminary positions, wrong date or day
indication, loss or gain of the time 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 operation on the next page.
