What Is a Rotor?
The rotor is an integral component of automatic watches, serving as the mechanism that winds the mainspring using the wearer’s natural wrist movements. Typically crafted from metal, the rotor is a semi-circular weight mounted on a pivot, allowing it to spin freely as the watch moves.
How Does the Rotor Work?
As the rotor oscillates, it transmits kinetic energy to the mainspring through a series of gears, effectively storing energy to power the watch. This self-winding mechanism eliminates the need for manual winding, ensuring that the watch remains operational as long as it’s worn regularly.
Why Is the Rotor Important?
The efficiency of the rotor directly influences the power reserve and reliability of an automatic watch. Innovations such as bi-directional winding rotors and the use of lightweight materials like tungsten have further enhanced their functionality. The rotor is often visible through exhibition case backs, offering a glimpse into the watch's mechanical artistry.
