BATTERY CHANGE 2 Years 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 SR927W battery. WARNING q Do not remove the battery from the watch. q 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. 17 English CAUTION q 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. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.
