3. Setup and Initial Operation
3.1 Unpacking and Inspection
Upon receiving your watch, carefully remove it from its packaging. Inspect the watch for any visible damage. Ensure all protective films are removed from the crystal and case back.
3.2 Winding the Watch
As an automatic watch, it is powered by the motion of your wrist. However, for initial setup or if the watch has stopped due to inactivity, manual winding is required:
- Locate the crown on the side of the watch case.
- Ensure the crown is in its original, pushed-in position (Position 0).
- Turn the crown clockwise approximately 20-30 times. This will provide enough power reserve to start the watch.
- The watch will continue to wind itself as you wear it. If worn daily for 8-10 hours, manual winding should not be necessary.

3.3 Setting the Time
- Pull the crown out to Position 1 (the first click).
- Turn the crown clockwise or counter-clockwise to set the main time.
- Once the desired time is set, push the crown back into Position 0.
3.4 Setting the Dual Time
The dual time sub-dial is typically set independently. Refer to the specific markings on your watch for the dual time adjustment mechanism, which is often a small pusher or a secondary crown.
- Locate the small recessed pusher on the side of the watch case, usually near the 10 o'clock position.
- Using a small, non-sharp tool (like a toothpick), gently press the pusher to advance the dual time hand.
- Continue pressing until the desired second time zone is displayed.

4. Operating Guidelines
4.1 Wearing the Watch
Wear the watch snugly but comfortably on your wrist. Consistent wear helps maintain the power reserve of the automatic movement. Avoid wearing the watch too loosely, as this can reduce winding efficiency and increase the risk of damage.
4.2 Water Resistance
Your watch has a water resistance rating of 5 ATM (50 meters). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water, such as showering or recreational swimming. It is not suitable for diving, snorkeling, or high-impact water sports. Always ensure the crown is fully pushed in before any contact with water.
Important: Do not operate the crown or pushers while the watch is wet or submerged, as this can compromise the water resistance.
4.3 Automatic Movement Operation
The automatic movement relies on kinetic energy generated by your arm's motion. If the watch is not worn for an extended period (typically 36-40 hours), the power reserve will deplete, and the watch will stop. To restart, manually wind it as described in Section 3.2.

5. Maintenance and Care
5.1 Cleaning
To clean your watch, gently wipe the case and crystal with a soft, dry, lint-free cloth. For the leather strap, avoid excessive moisture and harsh chemicals. If the strap becomes wet, allow it to air dry naturally, away from direct heat or sunlight.
5.2 Storage
When not wearing your watch, store it in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields. A watch box or a soft pouch is recommended to protect it from dust and scratches.
5.3 Service
For optimal performance, it is recommended to have your automatic watch serviced by a qualified watchmaker every 3-5 years. This includes cleaning, lubrication, and adjustment of the movement.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or is running slow. | Insufficient power reserve (not worn or wound enough). | Manually wind the watch by turning the crown clockwise 20-30 times. Wear the watch regularly. |
| Condensation under the crystal. | Sudden temperature change or compromised water resistance. | Avoid extreme temperature changes. If condensation persists, seek professional service immediately to prevent internal damage. |
| Time is inaccurate. | Magnetic interference, impact, or need for service. | Keep the watch away from strong magnetic fields. If accuracy issues persist after winding and wearing, professional service may be required. |
