2.1 Setting the Time
- Pull the crown (middle button) out to its outermost position.
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once set, push the crown back into its original position to start the watch.
2.2 Setting the Date
The watch features a complete calendar. The date window is typically located at the 3 o'clock position.
- Pull the crown (middle button) out to the first click position (halfway out).
- Turn the crown to adjust the date.
- Once the correct date is displayed, push the crown back into its original position.
- Note: Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
2.3 Adjusting the Strap
The watch comes with a leather strap with a pin buckle. Adjust the buckle to fit your wrist comfortably, ensuring it is not too tight or too loose.
3. Operating Instructions
3.1 Chronograph Function
The chronograph allows you to measure elapsed time. Refer to Image 2.1 for button identification.
- Start Timing: Press the top pusher to start the chronograph second hand.
- Stop Timing: Press the top pusher again to stop the chronograph. The elapsed time will be displayed on the sub-dials (seconds and minutes).
- Reset: After stopping the chronograph, press the bottom pusher to reset all chronograph hands to their zero positions.
3.2 Moon Phase Display
The watch features a 24-hour moon phase display, typically located in one of the sub-dials. This indicator shows the progression of day and night.

3.3 Luminous Display
The watch hands and hour markers are coated with a luminous material that absorbs light during the day and glows in the dark, allowing for readability in low-light conditions.

3.4 Water Resistance
This watch is rated for 30 meters (3 ATM) of water resistance. This means it is suitable for everyday use and can withstand splashes or brief immersion in water. However, it is NOT suitable for swimming, showering, diving, or any water sports where it might be subjected to high water pressure or prolonged immersion.

Important: Do not operate the crown or pushers when the watch is wet or submerged, as this can compromise the water resistance.
4. Maintenance
4.1 Cleaning
- Wipe the watch case and crystal regularly with a soft, dry cloth to remove dust and fingerprints.
- For the leather strap, wipe with a slightly damp cloth if necessary, then dry immediately. Avoid using harsh chemicals or abrasive materials.
4.2 Water Resistance Care
- After exposure to water (e.g., rain splashes), ensure the watch is thoroughly dried.
- Avoid exposing the watch to extreme temperature changes, as this can affect the water resistance seals.
- Have the water resistance seals checked periodically by a professional, especially if the watch is frequently exposed to moisture.
4.3 Leather Strap Care
- Avoid prolonged exposure to direct sunlight, extreme heat, or moisture, as these can cause the leather to dry out, crack, or fade.
- If the strap gets wet, allow it to air dry naturally, away from direct heat.
4.4 Battery Replacement
The watch is powered by a quartz movement, which uses a battery. When the watch stops or the second hand starts skipping, it indicates that the battery needs to be replaced. It is recommended to have the battery replaced by a qualified watch technician to ensure the watch's integrity and water resistance are maintained.
5. Troubleshooting
5.1 Watch Not Running
- Check if the crown is pushed all the way in. If it's pulled out, the watch will not run.
- The battery may be depleted. Refer to Section 4.4 for battery replacement.
5.2 Time Inaccurate
- Ensure the crown is fully pushed in after setting the time.
- Extreme temperatures or strong magnetic fields can affect quartz watch accuracy. Avoid such environments.
- If the inaccuracy persists, the movement may require servicing.
5.3 Chronograph Not Functioning Correctly
- Ensure the chronograph hands are reset to zero before starting a new measurement.
- If the hands do not reset to zero, or the chronograph does not start/stop, the mechanism may need inspection by a professional.
