BATTERY LIFE INDICATOR

● When the battery life indicator scrolls in the scroll window,

replace the battery with a new one as soon as possible.
Otherwise, the watch will stop operating in 2 to 3 days. We

2

Years

mately 2 years. However, because the battery is inserted at the
factory to check the function and performance of the watch, its actual

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 SR1130W battery.

* The battery life may be less than 2 years if:

• the alarm is used for longer than 20 seconds a day,

• the stopwatch is used for longer than 3 minutes a day,

• city selection is made more than 5 times a day,

• the confirmation sound is used more than 10 times a day, and/or
