DAY AND TIME SETTING
- To advance the day hand quickly, turn back the hour and minute hands 4 to 5 hours beyond the point the day normally changes, and then advance them again until the day hand is set to the next.
* The day hand will not move back by turning the crown counterclockwise. - When adjusting the day hand, turn the crown slowly.

- It is necessary to adjust the date to the end of February and the 30-day month.
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 malfunction. For battery replacement meant, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR920SW battery.
WARNING
- 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.
CAUTION
- 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.
