Setup
Your Luminox automatic watch is powered by the motion of your wrist. Before initial use or after a period of inactivity, it may require manual winding.
1. Initial Winding
- Unscrew the crown (if applicable) by turning it counter-clockwise until it springs out to position 1.
- Turn the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- Push the crown back in and screw it down clockwise to ensure water resistance.
2. Setting Time and Date
- Unscrew the crown and pull it out to position 3 (farthest out). The second hand will stop.
- Turn the crown to set the time. To avoid confusion between AM/PM, advance the time until the date changes. This indicates midnight.
- Pull the crown out to position 2 (middle position). Turn the crown to set the date.
- Once the date is set, push the crown back to position 3 and set the correct time.
- Push the crown back to position 1 and screw it down clockwise firmly to maintain water resistance.
3. Adjusting the Bracelet
The stainless steel bracelet can be adjusted by adding or removing links. This procedure typically requires specialized tools and is best performed by a qualified watchmaker or jeweler to prevent damage to the bracelet or watch.

Operating Your Watch
Automatic Movement
Your Luminox watch features an automatic movement, which means it is powered by the natural motion of your wrist. When worn regularly, the watch will self-wind and maintain its power reserve. If the watch is not worn for approximately 38 hours, it will stop and require manual winding as described in the Setup section.
Luminox Light Technology (LLT)
Luminox watches are equipped with a unique self-powered illumination system, Luminox Light Technology (LLT). This technology utilizes tiny gas tubes that provide a constant glow for up to 25 years, ensuring visibility in all lighting conditions without requiring external light exposure or battery power for illumination.

Unidirectional Rotating Bezel
The watch features a unidirectional rotating bezel, which can be used for timing events or tracking elapsed time. To use, align the triangle marker on the bezel with the minute hand at the start of the event. As time passes, the minute hand will indicate the elapsed time against the bezel's scale. The bezel rotates only counter-clockwise to prevent accidental shortening of measured time, a critical safety feature for divers.
Water Resistance
This watch has a water resistance rating of 200 meters (20 ATM / 660 feet). This makes it suitable for professional marine activity and serious surface water sports, but not for saturation diving. Always ensure the crown is fully screwed down before exposing the watch to water.

Maintenance
Proper maintenance ensures the longevity and accuracy of your Luminox watch.
Cleaning
- For stainless steel cases and bracelets, use a soft cloth dampened with mild soapy water. Gently wipe the surfaces.
- After cleaning, rinse with clean water (if water resistant and crown is screwed down) and dry thoroughly with a soft, lint-free cloth.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish or seals.
Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
Service Intervals
Like any precision instrument, your automatic watch requires periodic servicing to maintain optimal performance. It is recommended to have your watch serviced by an authorized Luminox service center every 3-5 years. This service typically includes cleaning, lubrication, and adjustment of the movement, as well as replacement of seals to ensure water resistance.

Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Insufficient power reserve. | Manually wind the watch by turning the crown clockwise 20-30 times. Wear the watch regularly to keep it wound. |
| Date changes at noon instead of midnight. | Time is set incorrectly (AM/PM). | Advance the time by 12 hours. |
| Condensation under the crystal. | Temperature change or compromised water resistance. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. |
| Crown does not screw down. | Cross-threaded or debris in threads. | Gently attempt to re-thread. If resistance persists, do not force it. Seek professional assistance. |
