4. Setup and Adjustment
Your OLEVS 9910 watch is an automatic mechanical timepiece. It is powered by the motion of your wrist. If the watch has stopped or is running low on power, it can be hand-wound.
4.1 Initial Winding
If the watch has not been worn for a period, it may require manual winding to start. Rotate the crown clockwise approximately 20-30 times while it is in its normal, pushed-in position. This will build up an initial power reserve.
4.2 Setting the Time
- Gently pull out the crown to the outermost position.
- Rotate the crown to set the hour and minute hands to the correct time.
- Push the crown back into its normal position to start the watch.
4.3 Setting the Calendar Functions
The watch features a dual calendar (date and day of the week) and a month sub-dial. There are adjustment buttons on the side of the watch case.

- Calendar Adjustment Button: Used to adjust the date.
- Month Adjustment Button: Used to adjust the month sub-dial.
- Function Buttons on the Left: Used to adjust the week sub-dial.
Important Note on Calendar Display: The calendar function uses an independent gear system. The single-digit disk for the date cycles from 0-9, and the tens-digit disk cycles from 0-3. Therefore, displaying numbers like '39' in the calendar window is a normal characteristic of the mechanical gear transmission cycle and not a quality problem. You should manually adjust the date to the 1st at the beginning of each month if it exceeds 31.
5. Operating Instructions
5.1 Automatic Winding
Once set, the watch will automatically wind itself through the natural motion of your arm while worn. For optimal performance, wear the watch for at least 8-10 hours a day.
5.2 Luminous Feature
The watch's hands and markers are coated with a high-definition luminous material. This material absorbs light during the day and glows in the dark, providing clear readability at night. Exposure to bright light will enhance the glow.

6. Maintenance
To ensure the longevity and optimal performance of your OLEVS 9910 watch, follow these maintenance guidelines:
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the metal bracelet, a slightly damp cloth can be used, followed by immediate drying.
- Water Exposure: While the watch is water-resistant to 30 meters, avoid exposing it to hot water, steam (e.g., in showers or saunas), or prolonged submersion. Always ensure the crown is fully pushed in before any contact with water.
- Avoid Chemicals: Keep the watch away from solvents, detergents, perfumes, and other chemical products that may damage the case, strap, or seals.
- Temperature Extremes: Avoid sudden temperature changes and extreme temperatures, which can affect the watch's accuracy and internal components.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones, computers) as these can interfere with the mechanical movement and affect timekeeping accuracy.
- Servicing: Mechanical watches benefit from periodic professional servicing, typically every 3-5 years, to clean, lubricate, and adjust the movement.
7. Troubleshooting
If you encounter any issues with your watch, refer to the following common problems and solutions:
- Watch has stopped or is losing time:
This is common for automatic watches if not worn regularly. Manually wind the watch (as described in Section 4.1) and wear it consistently for several hours. If the issue persists, it may require professional inspection. - Date/Day/Month display is incorrect:
Manually adjust the calendar functions using the dedicated buttons as described in Section 4.3. Remember to adjust the date to the 1st at the beginning of each month if the display shows numbers beyond 31. - Condensation or water inside the watch:
This indicates a breach in the watch's water resistance. Stop using the watch immediately and take it to a professional watch repair service as soon as possible to prevent further damage to the movement. - Bottom dial (balance wheel) is not moving:
The visible balance wheel on the dial should be in constant motion when the watch is running. If it's stationary, the watch has stopped. Refer to the 'Watch has stopped' solution above.
8. User Tips
- Regular Wear: For an automatic watch, consistent wear is the best way to keep it wound and accurate. If you rotate watches, consider a watch winder to keep your OLEVS 9910 running when not on your wrist.
- Appreciate the Craftsmanship: Many users praise the watch's excellent craftsmanship and luxurious appearance, noting it looks more expensive than its actual cost.
- Calendar Adjustment: Be mindful of the unique calendar mechanism. If the date display goes beyond 31, manually reset it to the 1st of the new month using the adjustment buttons.
