Instructions for Receiving Leap Second Data on Seiko Astron GPS Solar Watch
11
Thank you for purchasing a Seiko Astron Watch.
This watch enters the “leap second data” receiving mode after the first GPS signal is received on or
after December 1st and June 1st.
It is conducted every six months whether the leap second data is put into effect or not. This process
occurs automatically so no special operation is required from the user. The process of receiving the
leap second data takes longer than the regular time adjustment. Be sure to complete receiving the leap
second data in an environment where a GPS signal can be received, such as outdoors.
※When the second hand points to the one-second position, it is indicating that one minute is required before the
watch begins receiving the leap second data. At this time, it is recommended that you remain in an environment
where a GPS signal can be received, such as outdoors.
※Please refrain from button operation while the watch is in the data receiving mode.
For details, please read the Basic Manual (
P.18
).
About Leap Second
The leap second is to compensate for deviations from the “Universal Time”(UT) which is astronomically
The leap second is to compensate for deviations from the “Universal Time”(UT) which is astronomically
determined and the “International Atomic Time”(TAI). 1 second may be added (deleted) once a year or
every few years at the end of June or December.
The watch will repeatedly enter the “leap second data” receiving mode until the process is successfully
completed. During this time, no time adjustment will take place. In the event that the attempt to receive
leap second data is unsuccessful, indicated by position N (not successful), it is recommended you move to
a place where a GPS signal can be easily received, such as outdoors, and complete the process of receiving
time data and then leap second data through a GPS signal by pressing and holding button B for 3 seconds.
The second hand begins moving counter-clockwise and
displays the countdown in minutes until leap second data is
received.
This may require up to 18 minutes.
When the second hand has reached the 12 o'clock position,
reception of the leap second data beging. When reception is
good, the second hand moves to the 1 o'clock position and the
watch acquires the data (within approximately, one minute).
If the reception was successful, the second hand points to the
Y position indicating successful data transfer.
Button B
The indicator hand points
to the right side of the
4+ position.
The process of receiving leap second data
Although this movement is different from the normal time display, it is not an indication that the watch is defective.
