Preliminary position
When the date and time are not correct even if the radio signal reception is successful, the preliminary position of the
date may be misaligned.
The possible causes of misalignment of preliminary position are as follows:
In the case of having a strong impact
:
the misalignment may occur when dropping or hitting the watch.
In the case of a magnetic influence
:
the misalignment may occur when bringing the watch close to an object which
generates magnetism.
“Examples of common magnetic products that may affect watches” → P.47
* The condition “the preliminary position of hand is misaligned” means that compared to a health meter, “the zero position of a
meter is misaligned, causing a correct weight not to be displayed.”
■Automatic hand position adjustment function (Adjustment of
preliminary positions of hour, minute and seconds hands)
The hour, minute, and seconds hands have an “automatic hand position adjustment function,” which automatically
corrects an incorrect preliminary position. Automatic hand position adjustment function activates at 12:00 both for the
AM and PM for the hour and minute hands and once a minute for the seconds hand.
* 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.
“Set the preliminary position for the date, and the hour and minute hands.” → P.67
■ Preliminary position adjustment of the date
Since the preliminary position of the date is not automatically adjusted, it is necessary to align the position manually.
“Set the preliminary position for the date, and the hour and minute hands.” → P.67

How to set the preliminary position
■ 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 operation on the next page.
