Setup
1. Time and Date Setting
Unscrew the Crown: The watch features a threaded crown. Gently unscrew the crown counter-clockwise until it pops out to the first position.
Set the Date: Pull the crown out to the second click position. Turn the crown clockwise or counter-clockwise to adjust the date.
Set the Time: Pull the crown out to the third click position. Turn the crown to set the hour and minute hands. Ensure the AM/PM is correctly set if your watch has a 24-hour indicator or if you are setting the date.
Push and Screw Down the Crown: Once the time and date are set, push the crown back in and screw it clockwise firmly against the watch case to ensure water resistance.

2. Strap Adjustment
To adjust the length of the stainless steel strap, you will need the provided strap adjustment tool.
Locate the Triangle Mark: Find the small triangle mark on the watch band links, indicating the direction to push the connecting rod.
Push the Connecting Rod: Use the strap adjustment tool to push the connecting rod in the direction of the arrow.
Remove/Reinstall Links: Once the rod is pushed out, you can remove or add links as needed. Reinstall the connecting rod and push it back into place to secure the strap.

Operating Your Watch
1. Water Resistance (3ATM / 30 Meters)
Your WWOOR 8878 watch is designed with 3ATM (30 meters) water resistance. This means it is suitable for daily use, such as hand washing, rain, and cold baths. It is NOT suitable for swimming, diving, or hot water activities like showering with hot water or saunas, as extreme temperature changes can compromise the seals.
Image: Table detailing water resistance ratings and suitable activities (e.g., 3ATM is suitable for hand washing and rain, but not swimming or diving).
Important: Always ensure the crown is fully screwed down before exposing the watch to water.
2. Luminous Display
The watch features Super Luminous hands and markers, allowing for readability in low-light conditions. After exposure to light, the luminous elements will glow in the dark.

3. Unidirectional Rotating Bezel
The watch is equipped with a unidirectional rotating outer ring (bezel). This bezel can be rotated counter-clockwise and is typically used for timing events, such as dive times. Align the luminous triangle on the bezel with the minute hand at the start of an event to track elapsed time.

4. Chronograph and Stop Watch Functions
The WWOOR 8878 watch includes chronograph and stop watch features. Refer to the detailed instructions provided in the watch's specific movement manual for precise operation of these functions, as they typically involve the pushers located on the side of the watch case.
Maintenance
Cleaning: Wipe your watch regularly with the provided clean cloth to remove dust and smudges. For the stainless steel strap, a soft brush and mild soapy water can be used, followed by thorough rinsing and drying.
Avoid Chemicals: Do not expose your watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, and seals.
Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect its accuracy and water resistance.
Impact: Protect your watch from strong impacts or drops.
Battery Replacement: When the watch stops or the second hand starts skipping, it's time to replace the battery. This should ideally be done by a professional watchmaker to ensure the water resistance is maintained.
Troubleshooting
Watch is not running:
- Check if the crown is fully pushed in and screwed down. The watch will not run if the crown is pulled out for setting.
- The battery may be depleted. Replace the battery (recommended by a professional).
Date changes at noon instead of midnight:
- This indicates the watch is set to PM when it should be AM, or vice-versa. Advance the time by 12 hours.
Water inside the watch:
- Immediately take the watch to a professional watchmaker for inspection and repair. Do not attempt to open the watch yourself, as this will void any potential warranty and further damage the watch.
- Ensure the crown was fully screwed down before water exposure.
User Tips
While the watch is water-resistant, avoid prolonged exposure to water or high-pressure water jets to preserve its seals.
Regularly check the tightness of the strap pins, especially after adjusting the band, to prevent accidental detachment.
The luminous feature works best after sufficient exposure to bright light.
