Most watches need 1,000 to 1,900 revolutions per day to function properly.Our Startbox automatic watch winder performs 1,600 revolutions per day, meeting the requirements for most watches. However, if your watch has more specific needs, we recommend the Masterbox winder. Configured to perform 1,600 revolutions per day, the Masterbox has advanced features so that you can customise rotation cycles (the number of daily revolutions and direction of rotation) depending on the requirements of your automatic watch.
