BATTERY LIFE INDICATOR
●
When the battery nears its end, the small second hand moves at two-second intervals
instead of the normal one-second intervals. In that case, the watch will stop operating
in 2 to 3 weeks. Replace the battery with a new one as soon as possible.
* While the small second hand is moving at two-second intervals, the watch remains accurate but the
alarm will not ring.
●
While the small second hand is moving at two-second intervals, do not use the watch
for diving, as the watch does not measure the depth.
●
When the battery nears its end, the DEPTH hand
indicates the 58-minute position when button B is
pressed to reset the hands for diving measurement
to “0” position.
* When the log data is displayed, however, the DEPTH hand
does not indicate the 58-minute position.
The miniature battery which powers your watch should last approximately
2 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 CR2016 battery.
