3. Setup and Initial Operation
3.1 Winding the Watch
Your Orient RA-AA08 watch is powered by an automatic movement (Caliber F6922), which winds itself through the motion of your wrist. If the watch has stopped or has not been worn for an extended period, it can be manually wound:
- Ensure the crown is in position 0 (fully pushed in and screwed down).
- Unscrew the crown by turning it counter-clockwise until it springs out to position 1.
- Turn the crown clockwise approximately 30-40 times to provide sufficient power reserve.
- Push the crown back into position 0 and screw it down clockwise firmly to ensure water resistance.
Regular wear will keep the watch wound. A full power reserve typically lasts for approximately 40 hours.
3.2 Setting the Time and Date
To set the time and date on your watch:
- Unscrew the crown and pull it out to position 2. This will stop the second hand (hacking function), allowing for precise time setting.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands. Advance the hands past 12 o'clock to determine if it is AM or PM for correct date change.
- Once the time is set, push the crown back into position 1.
- Turn the crown clockwise to set the date and counter-clockwise to set the day. Note that the day display may show two languages (e.g., English and Spanish). The watch will cycle through both languages during the automatic day change process after midnight before settling on the selected language. Avoid setting the date or day between 9:00 PM and 3:00 AM, as this can damage the movement.
- After setting the date and day, pull the crown back out to position 2.
- Set the exact time again, synchronizing with a reliable time source.
- Push the crown back into position 0 and screw it down clockwise firmly to ensure water resistance.

4. Water Resistance Guidelines
The Orient RA-AA08 watch is water resistant to 200 meters (20 bar), making it suitable for skin diving and various water sports. However, it is important to adhere to the following guidelines to maintain its water resistance:
- Always ensure the crown is fully screwed down before exposing the watch to water.
- Do not operate the crown or pushers while the watch is submerged in water.
- Avoid exposing the watch to hot water, steam, or extreme temperature changes, as this can compromise seals.
- After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it with a soft cloth.
- Water resistance is not a permanent condition and may decrease over time due to wear and tear on gaskets. It is recommended to have the water resistance checked periodically by an authorized service center.
5. Maintenance and Care
Proper care will ensure the longevity and performance of your Orient RA-AA08 watch:
- Cleaning: Wipe the watch case and bracelet regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by thorough drying.
- Sapphire Crystal: The sapphire crystal is highly scratch-resistant but not entirely scratch-proof or shatter-proof. Avoid impacts and contact with extremely hard materials.
- Avoid Chemicals: Do not expose the watch to solvents, detergents, perfumes, or cosmetic products, as these can damage the seals, case, or bracelet.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones), as these can affect the accuracy of the mechanical movement.
- Servicing: Mechanical watches benefit from periodic servicing, typically every 3-5 years, to ensure optimal performance and water resistance. Contact an authorized Orient service center for professional maintenance.

6. Troubleshooting
- Watch Not Running: If the watch has stopped, manually wind it by turning the crown clockwise 30-40 times (after unscrewing to position 1). Ensure it is worn regularly to maintain power reserve.
- Incorrect Time/Date: Refer to section 3.2 for detailed instructions on setting the time and date. Ensure the crown is fully pulled out to the correct position for adjustment.
- Water Inside Watch: If you notice condensation or water inside the watch, immediately take it to an authorized service center. Do not attempt to dry it yourself, as this can cause further damage.
- Bracelet Adjustment: The stainless steel bracelet uses directional punch pins. For proper sizing, it is recommended to have the bracelet adjusted by a professional watchmaker.
