Setup Instructions
1. Setting the Time:
- Pull the crown out to the second position (farthest out).
- Rotate the crown to set the hour and minute hands. Observe the 24-hour sub-dial to ensure the correct AM/PM (day/night) setting.
- Once the desired time is set, push the crown back into the normal position.
2. Setting the Date:
- Pull the crown out to the first position (one click out).
- Rotate the crown to adjust the date. Avoid setting the date between 9:00 PM and 3:00 AM, as this may interfere with the automatic date change mechanism.
- Once the desired date is set, push the crown back into the normal position.
3. Chronograph Reset:
If the chronograph hands are not aligned to the 12 o'clock position after resetting, refer to the troubleshooting section or consult a professional watch repair service.
Operating Instructions
Using the Chronograph:
The chronograph function allows for precise measurement of elapsed time.
- Start: Press the top pusher to start the chronograph. The second chronograph hand will begin to move.
- Stop: Press the top pusher again to stop the chronograph. The elapsed time can be read from the second and minute chronograph sub-dials.
- Reset: After stopping the chronograph, press the bottom pusher to reset all chronograph hands to their zero positions.

Understanding the 24-Hour Indicator:
The sub-dial typically located at the 6 o'clock or 9 o'clock position displays a sun and moon image, indicating whether it is day or night. This sub-dial synchronizes with the main hour hand and cannot be set independently.
Luminous Function:
The hands and hour markers are coated with a luminous material. Exposure to light will charge this material, allowing the watch to glow in the dark for a period of time.
Maintenance
Cleaning:
Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For the leather strap, avoid excessive moisture and harsh chemicals.
Water Resistance:
The watch is water-resistant to 30 meters (3ATM). This means it is suitable for everyday use and can withstand splashes or brief immersion in water. It is not recommended for swimming, showering, or diving. Ensure the crown is fully pushed in before any contact with water.

Battery Replacement:
The watch is powered by a quartz battery. When the watch stops or the second hand begins to jump erratically, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
Strap Care:
The genuine leather strap should be kept dry and away from direct sunlight or extreme temperatures to prevent damage and prolong its lifespan. Avoid contact with oils, perfumes, and solvents.
Troubleshooting
- Watch Not Running:
Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement. - Time/Date Not Changing:
Ensure the crown is pulled out to the correct position for setting. If the date does not change automatically at midnight, check the AM/PM setting of the main time. - Chronograph Hands Not Resetting to Zero:
This may indicate a need for calibration or service. Consult a professional watch repair service. - Water Inside the Watch:
If condensation or water droplets appear inside the watch, immediately take it to a professional watch repair service to prevent further damage.
