BATTERY CHANGE
The miniature battery which powers your watch should last approximately
5 years
. However, because the battery is inserted at the factory to
check the function and pe rformance of the wat ch, its actual life onc e
in your possession may be less than the spe cified period. Wh en 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 battery.
* If the display mode is changed more than once, the stopwatch is used
for longer than 1 hour, and the alarm sounds for 20 seconds per day, the
battery life may be less than the specified period.
Battery life indicator
●
When the battery nears its end, the small second hand moves at two-second intervals
◆
instead of normal one-second intervals. In that case, have the battery replaced with a
newone as soon as possible.
* The watch remains accurate while the small second hand is moving at two- second
intervals.
