Setup and Initial Use
First-Time Winding:
Upon receiving your watch, it may not be running. As an automatic mechanical watch, it requires initial winding to build up power reserve. To do this:
- Ensure the crown is in its fully pushed-in position (position 0).
- Rotate the crown clockwise approximately 20 times. This will manually wind the mainspring and start the watch.
- Once started, the watch will continue to wind automatically with your daily wrist movements. If worn regularly (8-10 hours a day), manual winding should not be necessary.
Adjusting the Bracelet:
The stainless steel bracelet can be adjusted to fit your wrist size. The package includes a strap removal tool for this purpose. If you are unsure about adjusting the bracelet yourself, it is recommended to seek assistance from a professional jeweler.

Operating Instructions
Setting the Time:
- Gently pull the crown out to position 1.
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Once the time is set, push the crown back into its original position (position 0) to secure the setting and resume timekeeping.
Note: This model does not feature a date complication.
Maintenance and Care
Cleaning:
To maintain the appearance of your watch, regularly wipe the case and bracelet with the provided cleaning cloth. For more thorough cleaning, a soft, damp cloth can be used. Avoid using harsh chemicals or abrasive materials.
Water Resistance:
The watch is designed to be waterproof. However, it is important to ensure the crown is always fully pushed in before any contact with water to prevent damage. While suitable for daily wear and splashes, it is not recommended for swimming or diving unless explicitly stated otherwise in the specifications.
Storage:
When not wearing the watch for extended periods, store it in a cool, dry place away from direct sunlight and strong magnetic fields, which can affect the movement's accuracy.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Insufficient power reserve. | Manually wind the watch by rotating the crown clockwise approximately 20 times. Wear the watch regularly to ensure continuous winding. |
| Time is inaccurate. | Watch is not fully wound or exposed to magnetic fields. | Ensure the watch is fully wound. Keep the watch away from strong magnetic sources (e.g., speakers, refrigerators, smartphones). If inaccuracy persists, professional inspection may be required. |
| Condensation inside the watch. | Water ingress due to open crown or seal damage. | Immediately take the watch to a professional watchmaker for inspection and repair to prevent further damage. Ensure the crown is always fully pushed in when near water. |
