The automatic mechanical watch is an improvement of the manual mechanical watch. A swaying rudder is added to the watch. When worn, the oscillating weight in the watch is rotated by the wrist to achieve the effect of winding. The general automatic mechanical watch still retains the function of manually winding. 

In other words, you can still turn the crown to wind up. Only some cheaper automatic mechanical movements will omit the secondary function. Because the wrist's activity will keep the watch continuously wound, the automatic mechanical watch has a function to prevent the clockwork from being too tight so as to prevent breakage.
