What Is the Difference Between a Manual and an Automatic Watch?

Omega Co-Axial Caliber 9301

A manual watch, also referred to as a hand-wound mechanical watch, slowly unwinds the mainspring in an even motion releasing energy that powers the timepiece over a period of time.

An automatic mechanical, usually just called an automatic, requires no winding because of the rotor, which winds the mainspring every time you move.

The Omega Co-Axial Caliber 9301 pictured above is an example of an automatic movement.
