Discover the Functioning of the Rotor in Watchmaking


The rotor is an essential component of automatic movements in watchmaking. This mechanism allows the watch to be automatically wound by the kinetic energy generated by the movements of the wrist. In this article, we will discover the functioning and role of the rotor in automatic watches.


The Functioning of the Rotor

The rotor is a wheel that is connected to a gear train, it rotates thanks to the kinetic energy generated by the movements of the wrist. When the rotor rotates, it drives the gear train which, in turn, automatically winds the watch. It is a simple and effective system that allows the watch to be automatically wound without the need for manual intervention.

The Different Types of Rotors

There are several types of rotors, each with its own characteristics. The most common rotors are the standard rotor, the micro-rotor, and the off-centered rotor. Each of these types of rotors has its advantages and disadvantages, and it is important to understand them to choose the watch that best suits your needs.
