The age old question “what direction should I wind my watch on a watch winder?”. W&R created a helpful resource guide to assist with this very question. Why is this information important ? The rotor of an automatic movement winds the mainspring. The rotor “tightens” the mainspring creating power for the watch and the power reserve. The rotor will either wind the mainspring by rotating clockwise, counterclockwise, or in both directions. This list touches on some of the more common movements like ETA, ETA/Valjoux, Lemania, Sellita, Miyota, and a few popular individual watch brand movements. If you want to know what direction or the minimum rotations needed to keep your automatic movement wound this guide is for you.
