3. Setup and Initial Operation

3.1 Initial Winding

Your SEIKO 5 watch is powered by an automatic movement and does not require batteries. It winds itself through the motion of your arm. If the watch has stopped or is running low on power, it needs to be manually wound to initiate operation.

• Gently shake the watch from side to side in a horizontal arc for about 30 seconds. This motion will cause the oscillating weight inside to rotate, winding the mainspring.
• Alternatively, wear the watch for several hours. Normal daily activities will provide sufficient winding.

A fully wound watch will typically run for approximately 40 hours without further motion.

3.2 Setting the Time and Date

To set the time and date, follow these steps:

1. Pull out the crown: Locate the crown on the right side of the watch case. Gently pull it out to the first click position for date/day adjustment, and to the second click position for time adjustment.
2. Set the date and day: In the first click position, rotate the crown clockwise or counter-clockwise to set the desired date and day. Avoid setting the date/day between 9:00 PM and 4:00 AM, as this can damage the movement. If the current time falls within this period, first advance the time past 4:00 AM, then set the date/day.
3. Set the time: Pull the crown out to the second click position. Rotate the crown to move the hands clockwise until the correct time is displayed. When setting the time, ensure you pass 12 o'clock to correctly set AM/PM for the day/date change.
4. Push in the crown: Once the time and date are set, push the crown back into its normal position against the watch case. This will start the watch movement.

4. Operating Your Watch

4.1 Wearing the Watch

Ensure the watch band is adjusted to fit comfortably on your wrist. The tri-fold push-type clasp provides a secure closure. To open, press the buttons on the sides of the clasp. To close, fold the clasp until it clicks securely.

4.2 Water Resistance

This watch has a water resistance rating of 50 meters (5 ATM / 165 feet). This means it is suitable for everyday use, including splashes, rain, and brief immersion in water. It is not suitable for swimming, diving, or showering with hot water, as steam and temperature changes can compromise the seals.

• Always ensure the crown is fully pushed in before any contact with water.
• Do not operate the crown while the watch is wet or submerged.
• If the watch comes into contact with saltwater, rinse it thoroughly with fresh water and dry it with a soft cloth.

5. Maintenance and Care

5.1 Cleaning

To maintain the appearance of your watch:

• Wipe the case and crystal with a soft, dry cloth regularly to remove dust and fingerprints.
• For the metal bracelet, use a soft brush and mild soapy water to clean between the links. Rinse thoroughly with fresh water and dry completely.
• Avoid using harsh chemicals, solvents, or abrasive cleaning materials, as these can damage the watch's finish.

5.2 Storage

When not wearing your watch for extended periods, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. For automatic watches, a watch winder can be used to keep the movement running and maintain accurate time.

5.3 Periodic Inspection

It is recommended to have your watch inspected by an authorized SEIKO service center every 2-3 years. This inspection includes checking the movement, replacing gaskets, and ensuring water resistance.

6. Troubleshooting

• Watch has stopped: As an automatic watch, it requires motion to operate. If it has stopped, gently shake it for about 30 seconds or wear it for several hours to build up power.
• Time is inaccurate: Ensure the watch is sufficiently wound. If it gains or loses significant time, it may require adjustment by a professional watchmaker. Exposure to strong magnetic fields can also affect accuracy.
• Day/Date not changing: Check if the time is set correctly for AM/PM. The day/date mechanism typically changes around midnight. If the issue persists, ensure the crown is fully pushed in after setting.
• Condensation inside the crystal: This indicates a loss of water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
