BATTERY CHANGE
The miniature battery which powers your watch should last
approximately 4 years . 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
SR927SW(SB-AP) battery.
* If the calendar checking function is used frequently, the battery life may be less
than the specified period.
