Setup
Initial Winding
Your OLEVS automatic watch is powered by an original mechanical movement that winds automatically with wrist motion. For the first use, or if the watch has stopped due to inactivity, it requires manual winding. Gently wind the crown 30-40 times in a clockwise direction until you feel resistance. This will initiate the movement and build up the power reserve.
Strap Adjustment
The watch comes with a comfortable stainless steel strap. A complimentary adjustment tool is included to help you easily remove links and fit the strap to your wrist size. Ensure the strap is securely fastened after adjustment.

Operating Instructions
Setting Time and Date
Your OLEVS watch features a multi-functional dial with day, 24-hour, and date displays. The crown on the side of the watch is used for adjustments:
- First Gear (Calendar Adjustment): Gently pull the crown out to the first click. Rotate the crown to adjust the day and date.
- Second Gear (Time Adjustment): Pull the crown out to the second click. Rotate the crown to set the hour and minute hands. Push the crown back in completely to start the watch.

Luminous Function
The watch hands and hour markers are equipped with a high-definition luminous function, allowing for clear time reading in low-light conditions. The luminescence charges when exposed to light.

Maintenance
Water Resistance
This watch features a sealed waterproof case with a 30-meter water resistance depth. It can withstand short-term splashing or immersion in water, such as hand washing or light rain. It is not suitable for showering, swimming, diving, or any activities involving hot water or prolonged submersion.
Cleaning and Care
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and smudges.
- Avoid exposing the watch to extreme temperatures, strong magnetic fields, or harsh chemicals.
- If the watch comes into contact with saltwater, rinse it gently with fresh water and dry thoroughly.
Troubleshooting
Watch Not Running or Losing Time
- Ensure the watch has been sufficiently wound. For automatic watches, consistent wrist movement is required. If inactive for an extended period, manually wind the crown 30-40 times.
- Check if the crown is fully pushed in. If it's pulled out, the watch will not run.
Date/Day Not Changing Correctly
- Adjust the date/day using the first gear of the crown. Avoid adjusting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
