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.
Stop winding the watch when you feel the resistance. If you overwind the watch, the spring might break.
