The rotor of a self-winding or automatic watch swings with the natural movements of the wearer's body, especially the arms, and winds the spring. Hence, the wearer need not wind the watch.
Are there any errors in the above sentences?

Your sentence is well-phrased. However, you have removed the word 'rotor', the moving device which, when turned by the wearer's movements, winds the watch.
How should the sentence be rephrased with the word 'rotor' retained?
Many thanks in advance.
The rotor of a self-winding or automatic watch swings with the natural movements of the wearer's arm, thus winds the mainspring. Consequently, the wearer need not wind the watch.
BTW, I am a watch collector. My hobby is watches.
Your sentence is fine.
BTW, I am a also watch collector. I have about 40 watches, from Rolex to Ebel. However, besides Rolex and Ebel, the other watches are cheaper ones.
The rotor's kinetic energy is converted to the springs potential energy.
kinetic energy ≠ mechanical energy
