Preliminary Position; How To Correct The Preliminary - Seiko 8B63 Instructions Manual

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
