Frequently Asked Questions - 8V36 SEIKO

How do I set the time on my Seiko 8V36 watch?

To set the time, pull out the crown. When setting the minute hand, first advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact minute.

How do I set the ultrasonic alarm?

Turn the crown to set the alarm hand to the desired alarm time. For more precise setting, turn the alarm hand counterclockwise. If setting an alarm less than 2 hours ahead, first advance the alarm hand more than 2 hours ahead, then turn it back to the exact time. Pull out the crown to engage the alarm.

How do I disengage the alarm?

Push the crown back in to disengage the alarm. The alarm is set on a 12-hour basis.

How does the battery life indicator work?

When the battery nears its end, the second hand moves at two-second intervals instead of normal one-second intervals. This indicates that the battery needs to be replaced.

What type of battery does the Seiko 8V36 use?

It uses a Seiko SR43W miniature silver oxide battery. Only use this type for replacement, and we recommend visiting an authorized Seiko dealer.

How long does the battery last?

Approximately 2 years. However, if the ultrasonic alarm is used more than 10 seconds per day, battery life may be shorter.

What is the ultrasonic alarm?

The ultrasonic alarm uses a motor to vibrate the watch for 20 seconds at the set time. Ensure the bracelet fits snugly on your wrist to perceive the vibration clearly.

Why can't I feel the alarm vibration?

The vibration may not be clearly perceived during active sports or work involving arm movement. Make sure the bracelet fits snugly on your wrist.

Is it safe to replace the battery myself?

It is recommended to have the battery replaced by an authorized Seiko dealer. Do not remove the battery yourself; if removed, keep it away from children. Never short-circuit, heat, or recharge the battery.

What is the accuracy of the watch?

The watch has a monthly rate of less than ±15 seconds at normal temperature range (5°C to 35°C). The alarm accuracy is ±5 minutes.

NOTES ON ULTRASONIC ALARM

• The alarm can be set on a 12-hour basis.
• When using the ultrasonic alarm, make sure that the watch bracelet fits snugly on your wrist so that the vibration of the watch can be perceived clearly.
• Please note that, while you are engaged in an active sport or work requiring arm movement, the vibration of the watch may not be perceived clearly.
• The alarm time scale may be graduated differently depending on the model. When reading the current time, take care not to mistake the alarm time scale for the current time scale.

BATTERY LIFE INDICATOR

When the battery nears its end, the second hand moves at two-second intervals instead of normal one-second intervals to indicate that the battery needs to be replaced with a new one.

BATTERY CHANGE

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 SR43W battery.

* The battery life may be less than 2 years if the ultrasonic alarm is used more than 10 seconds a day.
* When the battery nears its end, the ultrasonic motor runs slowly. In that case, replace the battery with a new one. (The time accuracy is not affected)

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.
