- To Set Date: Pull the crown out to Position 2. Rotate the crown clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement. Push the crown back to Position 1.
2. Adjusting Moon Phase

Operating Instructions
1. Chronograph Function
The chronograph measures elapsed time using the sub-dials at 9 o'clock (minute timer) and 6 o'clock (second timer).
- Start/Pause: Press the top push-button (located at 2 o'clock) to start the chronograph. Press it again to pause.
- Reset: While the chronograph is paused, press the bottom push-button (located at 4 o'clock) to reset all chronograph hands to zero.
2. Second Time Zone (Dual Time)
The second time zone is displayed on the sub-dial at the 3 o'clock position.
- Pull the crown out to Position 2.
- Press and hold the top push-button (at 2 o'clock) until the second time zone sub-dial pointer rotates to the desired time.
- Push the crown back to Position 1 to complete the setting.
3. Luminous Display
The watch hands and hour markers contain luminous material. For optimal glow in dark conditions, expose the watch dial to a bright light source (natural or artificial) for a few minutes. The absorbed light energy will allow the watch to glow in low-light environments.

4. Water Resistance
This watch is water-resistant up to 30 meters (3 ATM/3 BAR). This means it is suitable for daily use and can withstand splashes or brief immersion in water. It is not suitable for swimming, diving, showering with hot water, or any activities involving prolonged water exposure or high-pressure water jets. Always ensure the crown is fully pushed in before any contact with water.

Maintenance
- Cleaning: Wipe the watch case and band regularly with a soft, dry cloth to remove dust and dirt. For stainless steel bands, a slightly damp cloth can be used, followed by a dry cloth.
- Water Resistance Care: Avoid exposing the watch to extreme temperature changes, as this can affect the water-resistant seals. Always ensure the crown is fully pushed in after any adjustments to maintain water resistance.
- Battery Replacement: This watch uses a quartz movement, powered by a battery. When the battery runs low, the watch may stop or the second hand may jump. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and function.
- Storage: When not in use, store your watch in a cool, dry place, away from direct sunlight and strong magnetic fields.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Incorrect Time/Date: Refer to the "Setting Time and Date" section to correctly set the watch.
- Luminous Feature Not Glowing: Ensure the watch has been exposed to sufficient light to charge the luminous material.
- Water Inside Watch: If condensation or water appears inside the watch, have it inspected by a professional immediately to prevent damage to the movement.
