Manual movement vs automatic movement

The substantial difference between the manual and automatic movement of a mechanical watch concerns the source that feeds the mechanism.

The movement manual requires the owner's intervention which, by winding the mainspring via the crown, ensures its functioning until the next winding.

As a rule, for a mechanical watch, the average time between one recharge and the next can vary from 12/24 hours to the 2/5 days . It all depends on the power reserve possessed.

The automatic movement , unlike the mechanical one, uses a oscillating rotor to wind the spring completely independently.

The rotor is in turn connected to a motion axis which moves back and forth each time the watch is worn. The motion then turns the rotor, which, in turn, winds the spring.
