The battery life is the estimated life for a
watch with a new battery installed. The
battery in your watch at the time of purchase
was inserted in the watch at the factory for
performance checks. It may run down earlier
than the above-specified period.
○ When the battery nears its end, the second
hand moves at two-second intervals
instead of normal one-second intervals. The
watch remains accurate while the second
hand is moving at two-second intervals.

INTERCALARY SECOND (LEAP SECOND)
Normally there are 86,400 seconds in a day. Due to a slight change in the earth's
rotation, an extra second may be added to one day during the year. This is called
the intercalary second. Every year the decision is made whether such an
adjustment is needed. When the adjustment takes place, the standard time
should be corrected by delaying the standard time one second. To keep your
SEIKO watch accurate with the world standard time, adjust your watch to a time
signal whenever such adjustment is made. According to the information from the
observatories all over the world, the standard time is delayed one second
simultaneously throughout the world by the Greenwich Royal Observatory. In the
Greenwich Mean Time, an extra second will be added to the one minute between
11:59 p.m. and 0:00 a.m. either on December 31st or on June 30th. However,
the adjustment may not be made in some years. Please check by a newspaper,
etc. whether such an adjustment will be made or not.
