3. Setup and Initial Use
3.1 Unboxing and Inspection
Upon receiving your OUPINKE watch, carefully remove it from its packaging. Inspect the watch for any visible damage or manufacturing defects. Ensure all accessories, such as the band adjustment tool, are present.

3.2 Winding the Watch
As a mechanical watch, it requires initial winding if it has stopped. To wind the watch:
- Ensure the crown is in its fully pushed-in position (Position 0).
- Rotate the crown clockwise approximately 30-40 times. You will feel a slight resistance as the mainspring tightens. Do not overwind.
- The watch will begin to run. For automatic winding, simply wear the watch regularly. Your wrist's natural movements will keep the mainspring wound.
3.3 Setting the Time
To set the time on your OUPINKE watch:
- Gently pull the crown out to Position 1 (the outermost position).
- Rotate the crown clockwise or counter-clockwise to adjust the hour and minute hands to the correct time.
- Once the time is set, push the crown back into Position 0.
3.4 Adjusting the Band
The tungsten steel band can be adjusted to fit your wrist using the provided tool. If you are unfamiliar with watch band adjustments, it is recommended to seek assistance from a professional jeweler to avoid damage.

4. Operation and Care
4.1 Wearing the Watch
Wear your OUPINKE watch regularly to maintain its automatic winding. The watch is designed for daily wear and complements various styles.

4.2 Water Resistance
The watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for daily use, such as hand washing, rain, and brief immersion in water. It is not recommended for swimming, diving, or prolonged exposure to water, especially hot water or steam, as this can compromise the seals.

4.3 General Care
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and fingerprints. For the metal band, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the seals, finish, or crystal.
- Temperature Extremes: Avoid sudden temperature changes or extreme temperatures, which can affect the watch's accuracy and water resistance.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as they can interfere with the mechanical movement and affect timekeeping accuracy.
- Impact: While durable, avoid dropping or subjecting the watch to severe impacts.
5. Troubleshooting
If you encounter any issues with your OUPINKE watch, please refer to the following common troubleshooting tips:
- Watch Not Running: If the watch has stopped, manually wind it by rotating the crown clockwise 30-40 times while in Position 0. If it still does not start, ensure it has been worn sufficiently for automatic winding.
- Inaccurate Time: Mechanical watches can be affected by magnetic fields or impacts. If the time is consistently inaccurate, try demagnetizing the watch (a professional jeweler can assist) or ensure it has not been subjected to strong impacts.
- Condensation Inside Crystal: If you notice condensation, it may indicate a breach in the water resistance. Avoid further water exposure and seek professional service immediately.
For issues not resolved by these steps, please contact customer support.
