Setup and Initial Operation
Upon receiving your Orient Bambino watch, it may not be running. This is normal for mechanical watches that have been stationary.
Winding the Watch
- Hand-Winding: To initiate movement, rotate the crown clockwise in its normal position (position 0) for approximately 20-30 turns. This will build up a power reserve.
- Automatic Winding: The watch is equipped with an automatic movement that winds itself through the motion of your wrist. Wearing the watch regularly will keep it wound.
Setting Time and Date/Day
- Pull the Crown: Gently pull the crown out to position 2 for quick date/day adjustment, or to position 3 for time adjustment.
- Adjust Date/Day (Position 2): Rotate the crown counter-clockwise to adjust the date. Rotate clockwise to adjust the day of the week. Important: Avoid adjusting the date/day between 9:00 PM and 3:00 AM, as this can damage the movement. If adjustment is needed during this period, first set the time outside this range, adjust the date/day, then reset the time.
- Adjust Time (Position 3): Rotate the crown to set the hour and minute hands. The second hand will stop (hacking feature) when the crown is in this position, allowing for precise time setting.
- Push the Crown Back: Once set, push the crown back into its normal position (position 0) to start the watch and ensure water resistance.

Operating Your Automatic Watch
Your Orient Bambino watch is powered by a sophisticated mechanical movement.
Mechanical Movement
The watch operates without a battery, relying on the kinetic energy generated by your arm's motion. When worn, an oscillating weight inside the watch rotates, winding the mainspring. If the watch is not worn for an extended period, the power reserve will deplete, and the watch will stop. Simply hand-wind it or wear it again to restart.
Water Resistance
This watch has a water resistance rating of 3 meters (3 ATM). This means it is resistant to splashes and light rain, but it is not suitable for swimming, showering, or diving. Exposure to hot water or steam can compromise the seals. Always ensure the crown is fully pushed in to maintain water resistance.

Maintenance and Care
Proper care will help preserve the appearance and functionality of your watch.
- Cleaning: Wipe the case and crystal with a soft, dry cloth. For the leather strap, avoid excessive moisture and harsh chemicals.
- Avoid Shocks: Mechanical watches are delicate. Avoid dropping the watch or exposing it to strong impacts.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices), as magnetism can affect timekeeping accuracy.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures, both hot and cold.
- Service: It is recommended to have your mechanical watch serviced by an authorized watchmaker every 3-5 years to ensure its continued accuracy and proper functioning.

Troubleshooting
If you encounter issues with your watch, consider the following common solutions:
- Watch Has Stopped:
- Ensure the watch has sufficient power reserve. Hand-wind it 20-30 times.
- Wear the watch for several hours to allow the automatic movement to wind it.
- Inaccurate Timekeeping:
- Check if the watch has been exposed to strong magnetic fields. A demagnetizer or professional service may be required.
- Mechanical watches have a specified accuracy range (+25 to -15 seconds per day for this model). Minor deviations are normal.
- If accuracy is significantly outside the specified range, the watch may require regulation by a professional.
- Date/Day Not Changing:
- Ensure the time is set correctly, especially AM/PM. The date/day changes around midnight.
- Avoid manual date/day adjustment during the forbidden period (9:00 PM - 3:00 AM).
For issues not resolved by these steps, please contact an authorized service center.
