REMARKS ON USING THE WATCH
● This watch is not water resistant, and care should be taken not to get it wet.
Also, do not touch the hour and minute hands with wet fingers, as this will adversely
affect the time accuracy.
If the watch becomes wet, have it checked by an AUTHORIZED SEIKO DEALER or
SERVICE CENTER.
● As the front cover is opened and closed every time you read the time, we recommend
that the push pin supporting it be replaced with a new one once a year.
BATTERY CHANGE
Cal. 2A27 &
The miniature battery which powers your watch should last approximately
2 years (Cal. 2A27 and Cal. 4J27) / 5 years (Cal. 7C17). 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 SR621SW (Cal. 2A27) / SEIKO SR521SW (Cal. 4J27) /
SEIKO SR43SW (Cal. 7C17) battery.
