Warning regarding hand winding on SW200
Sellita recommends the use of hand winding to be limited only to start the movement to preserve the longevity of the rachet wheel.
Therefore use hand winding to start the movement, then use the automatic rotor to wind up the movement to full wind.1d. Removal and installation of stem and crown

FINAL CHECK!
Check for proper watch functions by winding and setting time. When hands are being turned, check if they come into contact with other hands or parts.
Check for dust or dirt on crystal, hands, dial or other parts. If needed, you can remove the case to clean the inside.
Check if the case back is securely fastened. If not, water resistance capability of the watch might be compromised.
