2. Setup and Initial Winding
Your MEGIR automatic mechanical watch is powered by the motion of your wrist. Before initial use or after a period of inactivity, it requires manual winding to build up its power reserve.
- Manual Winding: With the crown in its normal, pushed-in position, turn the crown clockwise approximately 10 to 20 times. This will initiate the movement and build a sufficient power reserve.
- Automatic Winding: Once manually wound, the watch will continue to wind itself through the natural motion of your arm while worn. For optimal performance, wear the watch daily for at least 8-10 hours.
If the watch stops, repeat the manual winding process.
3. Operating Instructions
Setting the Time:
- Pull out the Crown: Gently pull the crown outwards to the second position. You will feel a slight click.
- Adjust the Time: Turn the crown in either direction to set the hour and minute hands to the correct time.
- Push in the Crown: Once the time is set, push the crown back into its original, fully pushed-in position. This will restart the watch movement.

4. Water Resistance (3ATM)
This MEGIR watch is rated for 3 ATM (Atmospheres) water resistance. This means it is designed to withstand:
- Accidental splashes
- Rain
- Hand washing
Important: 3ATM water resistance is not suitable for showering, bathing, swimming, diving, or any water sports. Avoid pressing the crown or buttons while the watch is wet, as this can compromise the water seal.
5. Maintenance and Care
Proper care will ensure the longevity and performance of your MEGIR automatic mechanical watch.
- Cleaning: Wipe the watch case and band regularly with a soft, dry cloth. For the silicone band, a damp cloth with mild soap can be used, then rinse and dry thoroughly.
- Avoid Extreme Temperatures: Do not expose the watch to extreme heat or cold, as this can affect the movement and materials.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as they can interfere with the mechanical movement's accuracy.
- Impact: Avoid dropping the watch or subjecting it to strong impacts.
- Servicing: Mechanical watches benefit from periodic servicing by a qualified watchmaker, typically every 3-5 years, to ensure optimal performance and lubrication.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently. | Insufficient power reserve. | Manually wind the watch by turning the crown clockwise 10-20 times. Wear the watch regularly for at least 8-10 hours daily. |
| Time is inaccurate. | Exposure to strong magnetic fields; watch needs regulation. | Keep away from magnetic sources. If inaccuracy persists, consult a watchmaker for regulation. |
| Condensation under the crystal. | Water ingress due to compromised seal or extreme temperature changes. | Immediately take the watch to a qualified watchmaker for inspection and repair to prevent further damage. |
