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.
Automatic leap second reception function
A leap second is automatically added by receiving "leap second data" from GPS signals
at the time of leap second addition (deletion).
* "Leap second data" includes information about future leap second addition and current leap second data.

Receiving leap second data
When the GPS signal reception (automatic time
adjustment, manual time adjustment, or time zone
adjustment) is performed on or after December 1st and
June 1st, the multi-function indicator hand may display
as shown at the right.
When the leap second data reception is completed, the
multi-function indicator hand returns to display the day
of the week (or the charging status). Use the watch as it
is.
* The leap second data reception is performed every half a year regardless
of leap second addition.
After the completion of time adjustment (automatic time adjustment or manual time
adjustment), up to 18 minutes may be required until receipt of leap second data is
complete.
When GPS signals are received under the following conditions, the leap second data
reception is also started.
• GPS signals have not been received for a long time
• Leap second data reception has failed
With GPS signal reception, leap second data reception will be performed again. This will
continue until leap second data reception is successful. Confirm the result (success or
failure) of the leap second data reception.
