intervals.

BATTERY CHANGE

The miniature battery which powers your watch should last approxi-

mately 3 years. However, because the battery is inserted at the fac-

tory to check the function and performance of the watch, its actual life

once in your possession may be less than the speciﬁ ed period. When

the battery expires, be sure to replace it as soon as possible to pre-

vent any mal function. For battery replacement, we recommend that

you contact an AU THORIZED SEIKO DEALER and request SEIKO

SR927W battery.

※ If the yacht timer is used more than 6 hours per week, the timer is used more

than 15 minutes per day, the stopwatch is used more than 60 minutes per day

and the alarm sounds more than 40 seconds per day, the battery life may be

less than the speciﬁ ed period.
