How does an Automatic Watch work?

An automatic watch, also known as self-winding watch, is a wristwatch with a mechanical movement that is wound up by the natural arm movement that occurs when it is worn. During this process, the rotor in the movement is moved and transmit the torque to the winding mechanism via a tension spring.

Rotors with a bidirectional mechanism winding up the spring in both directions. If there is only one direction of rotation by the rotor, the spring is drawn unidirectionally.

It is precisely these properties that are decisive when setting the Watch Winder so that the watch is wound up in the correct direction of rotation.

MODALO Watch Winder support all common automatic watches (pilot watches, submarine watches / diving watches, sports chronographs) and guarantee the best possible value retention and constant readiness for daily use of the watch.
