BATTERY CHANGE

The miniature battery which powers your watch should last approximately 3 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 mal function. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR927W battery.
* If the alarm rings for more than 20 seconds a day, the battery life may be less than the specified period.
* After the battery is replaced with a new one, set the time/calendar and adjust alarm and world time hands.

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 new one as soon as possible.
* While the small second hand is moving at two-second intervals, the alarm will not ring even if it is engaged. This is not a malfunction.
* The watch remains accurate while the small second hand is moving at two-second intervals.

• Do not remove the battery from the watch.
• If it is necessary to take out the battery, keep it out of the reach of children. If a child swallows it, consult a doctor immediately.

• Never short-circuit, heat or otherwise tamper with the battery, and never expose it to fire.
• The battery may burst, become very hot or catch fire. l The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.
