A micro rotor, also known as a miniature oscillating weight, is a balanced rotating component commonly found in automatic and self-winding watches. It rotates with the movement of the wearer's wrist, continuously winding the main spring of the watch. This allows the watch to operate without the need for manual winding or hand winding. The micro rotor can rotate in one direction or bidirectionally.

The micro rotor is typically installed in the back part of the watch and is often visible through a transparent glass. It is considered an advanced technology in watchmaking, offering a combination of elegance and mechanical performance.
