3. Setup
3.1 Initial Winding
As an automatic mechanical watch, it is powered by the motion of your wrist. However, for initial use or after a period of inactivity, manual winding is recommended to ensure sufficient power reserve.
- Ensure the crown is in position 1 (fully pushed in).
- Rotate the crown clockwise approximately 30-40 times. This will provide enough power for the watch to start ticking and build up its power reserve through normal wear.
3.2 Setting Time and Date
To set the time and date:
- Setting Time: Pull the crown out to position 3 (farthest out). Rotate the crown to move the hands clockwise until the correct time is displayed. Push the crown back to position 1.
- Setting Date and Day: Pull the crown out to position 2 (middle position). Rotate the crown clockwise or counter-clockwise to adjust the date and day indicators. Avoid adjusting the date or day between 9 PM and 3 AM, as this can damage the movement. Push the crown back to position 1.
3.3 Strap Adjustment
The watch comes with a strap adjustment tool. To adjust the length of the tungsten steel bracelet:

- Identify the pins on the underside of the bracelet links.
- Use the provided tool to push out the pins in the direction of the arrows (if present) on the inner side of the links.
- Remove the desired number of links to achieve a comfortable fit.
- Reinsert the pins to secure the bracelet. Ensure the hidden butterfly buckle closes securely.
4. Operating Instructions
4.1 Automatic Winding
Your OUPINKE watch is equipped with an automatic movement. It winds itself through the natural motion of your arm. When worn daily for at least 8-10 hours, it should maintain sufficient power. If the watch is not worn for an extended period, it may stop and require manual winding as described in Section 3.1.
4.2 Water Resistance
The watch is water-resistant up to 50 meters (5 ATM).

- Suitable for: Daily use, hand washing, cold showers, shallow swimming.
- Not suitable for: Hot baths, hot showers, sauna, diving, or any activity involving high-pressure water or prolonged submersion.
- Always ensure the crown is fully pushed in before exposing the watch to water.
4.3 Luminous Display
The watch hands and markers are coated with a luminous material that absorbs light during the day and emits a glow in low-light conditions, allowing for clear time reading at night.

5. Maintenance
5.1 Cleaning
Regular cleaning helps maintain the appearance of your watch:
- Wipe the watch case and bracelet with a soft, dry cloth.

5.3 Avoiding Magnetic Fields
Mechanical watches can be affected by strong magnetic fields, which may cause them to run inaccurately. Keep your watch away from strong magnets, such as those found in speakers, refrigerators, and certain electronic devices.
5.4 Regular Servicing
Like any precision instrument, your mechanical watch benefits from periodic professional servicing. It is recommended to have your watch inspected by a qualified watchmaker every 3-5 years to ensure its continued accuracy and water resistance.
6. Troubleshooting
If you encounter any issues with your OUPINKE watch, please refer to the following common problems and solutions:
- Watch Stops Running:
- Cause: Insufficient power reserve.
- Solution: Manually wind the watch by rotating the crown 30-40 times clockwise (crown in position 1). Wear the watch regularly to allow the automatic movement to build up power.
- Time is Inaccurate:
- Cause: Exposure to magnetic fields, low power reserve, or need for adjustment.
- Solution: Ensure the watch is fully wound. Keep it away from strong magnetic sources. If inaccuracy persists, professional servicing may be required.
- Date/Day Not Changing:
- Cause: Incorrect setting, or adjustment during the restricted period (9 PM - 3 AM).
- Solution: Adjust the date/day using the crown in position 2, ensuring it is outside the restricted time window. If the issue continues, consult customer support.
- Condensation Under Crystal:
- Cause: Water ingress due to improper sealing or exposure to extreme temperature changes.
- Solution: This indicates a potential breach in water resistance. Stop using the watch immediately and seek professional repair to prevent further damage.
