1. Setting Time and Date
- Pull the crown out to position 2 (first click) to set the date. Turn the crown clockwise or counter-clockwise until the correct date is displayed.
- Pull the crown out to position 3 (second click) to set the time. Turn the crown to move the hour and minute hands to the desired time. Push the crown back to position 1 (normal position) to start the watch.
2. Adjusting the Leather Strap
The watch features an elegant leather strap with a buckle closure. Adjust the strap by inserting the pin into the appropriate hole for a comfortable and secure fit on your wrist. Ensure it is not too tight to allow for proper circulation.
Operating Instructions
1. Chronograph Function
The chronograph allows for precise time measurement.
- Start/Stop: Press the upper pusher (button A) to start the chronograph. Press it again to stop.
- Reset: With the chronograph stopped, press the lower pusher (button B) to reset all chronograph hands to zero.

The dial is treated with Super-LumiNova, providing excellent readability in the dark. Exposure to light charges the luminous material, causing it to glow blue in low-light conditions.

Maintenance
1. Leather Strap Care
To ensure the longevity of your leather strap, it is recommended to remove the watch before showering or swimming. The strap can be cleaned with a damp cloth and a special leather cleaner. Avoid prolonged exposure to direct sunlight or extreme temperatures.
2. Watch Case Cleaning
Wipe the stainless steel case and K1 mineral crystal with a soft, dry cloth to remove dust and fingerprints. For more stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive materials.
3. Battery Replacement
The watch is powered by one Lithium Metal battery. When the watch stops or the functions become erratic, it is likely time for a battery replacement. It is recommended to have the battery replaced by a qualified watchmaker to ensure proper sealing and maintain water resistance.
Troubleshooting
- Watch Not Running:
Ensure the crown is fully pushed in to position 1. If the watch still does not run, the battery may need replacement. See "Battery Replacement" in the Maintenance section.
- Incorrect Time/Date:
Refer to "Setting Time and Date" in the Setup section to correctly adjust the watch.
- Chronograph Hands Not Resetting to Zero:
If the chronograph hands do not reset to their zero position after pressing the reset pusher, a calibration may be required. Consult a professional watchmaker for adjustment.
