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.45
* 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.

influence.

The preliminary position of the date is the "1st".
The preliminary positions of the hour and minute hands are
"0:00 AM".
