Maintenance of a hand wind watch
The Automatic Business O501 is an automatic self-wind mechanical watch, which means that it doesn't require a battery. Hand-wound watches need to be winded before use. After the first winding, the watch will keep moving and winds itself automatically from natural hand movement if used at least 8 hours during the day.
How to wind a hand-wound watch?
Pull out the crown
Screw the crown anti-clockwise to the current time
Push the crown back
Turn the crown clockwise until you feel the resistance (about 10-15 rounds)
Stop winding the watch when you feel the resistance. If you overwind the watch, the spring might break.
