Setup
1. Initial Winding
As an automatic watch, the Orient RA-AK00 is powered by the motion of your wrist. However, for initial setup or after a period of inactivity, manual winding is recommended.
- Ensure the crown is in position 1 (fully pushed in).
- Rotate the crown clockwise approximately 30-40 times. This will provide enough power reserve to start the watch.
- The second hand should begin to move.
2. Setting Time, Day, and Date
To prevent damage to the delicate internal gears, it is crucial to avoid changing the date manually between 9 PM and 3 AM, as the watch automatically advances the date during this period. Follow these steps:
- Pull the crown out to position 2 (first click).
- Rotate the crown to set the time to approximately 6:30 (hands pointing downwards). This ensures the watch is outside the 'danger zone' for date changes.
- Pull the crown out to position 3 (second click). The second hand will stop (hacking feature).
- Rotate the crown to set the correct time. Ensure you differentiate between AM and PM for the 24-hour dial and day/date change.
- Push the crown back to position 2.
- Rotate the crown clockwise to set the date to the day prior to the current date.
- Rotate the crown counter-clockwise to set the day to the day prior to the current day.
- Pull the crown out to position 3 again.
- Advance the time by rotating the crown clockwise until the date and day change to the current date and day. Continue advancing the hands to the current time, ensuring the 24-hour indicator is correct.
- Once the correct time, day, and date are set, push the crown back to position 1 (fully pushed in) to secure it and ensure water resistance.

Operating Instructions
Automatic Movement
Your Orient RA-AK00 watch is equipped with an automatic movement. This means it is powered by the natural motion of your wrist. When worn regularly (typically 8-10 hours a day), the watch will remain wound and keep accurate time. If the watch is not worn for an extended period, it will stop. Simply manually wind it as described in the 'Initial Winding' section or wear it for a few hours to restart it.
Hacking Feature
The F6B24 movement includes a hacking feature. This allows the second hand to stop when the crown is pulled out to position 3, enabling precise time setting.
Water Resistance
The watch is water resistant to 50 meters (165 feet). This rating means it can withstand splashes, rain, and brief immersion in water, such as during recreational swimming. It is not suitable for diving, snorkeling, or prolonged water activities. Always ensure the crown is fully pushed in to maintain water resistance.
Maintenance
Cleaning
To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth regularly. For the leather strap, avoid excessive moisture and harsh chemicals. If the watch comes into contact with saltwater, rinse it gently with fresh water and dry thoroughly.
Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields, which can affect the movement's accuracy.
Regular Servicing
Like any mechanical timepiece, your Orient automatic watch benefits from periodic servicing by a qualified watchmaker. This typically involves cleaning, lubricating, and adjusting the movement to ensure optimal performance and longevity. The recommended service interval is generally every 3-5 years.
Troubleshooting
Watch Not Running
- Insufficient Power Reserve: If the watch has stopped, manually wind it by rotating the crown clockwise 30-40 times.
- Lack of Movement: Ensure you are wearing the watch regularly enough for the automatic movement to stay wound.
Incorrect Time/Date
- Setting Procedure: Review the 'Setting Time, Day, and Date' section to ensure the correct procedure is followed, especially regarding the 'danger zone' for date changes.
- Magnetic Fields: Exposure to strong magnetic fields can affect accuracy. If you suspect this, consult a watchmaker for demagnetization.
Water Exposure
- If moisture appears inside the watch, immediately take it to a qualified watchmaker. This indicates a breach in water resistance that needs urgent attention to prevent damage to the movement.
