The leap second correction is executed every year or two simultaneously throughout the
world on the basis of information collected by astronomical observatories all over the world.
The correction is effected between 11:59'59" p.m. and 0:00'00" a.m. GMT either on December
31 or on June 30, during which one second is added or subtracted.
When this happens, please adjust your watch accordingly.
Please refer to your newspaper for information on the leap second.
BATTERY CHANGE
The miniature battery which powers your watch should last approximately
5 years (Cal. 4F56)
/
10 years (Cal. 8F56)
. However, because the battery
is inserted at the factory to check the function and performance of the watch,
its actual life once in your possession may be less than the specified period.
When the battery expires, be sure to replace it as soon as possible to prevent
any malfunction. For battery replacement, we recommend that you contact
an AUTHORIZED SEIKO DEALER and request
SEIKO CR1612 (Cal. 4F56)
/
SEIKO CR2412 (Cal. 8F56)
battery.
