A watch winder is an essential accessory for anyone who owns an automatic watch. These types of watches contain an internal weighted rotor which rotates inside the watch to keep the mainspring properly wound. When the watch is being worn the movement of your arm keeps the rotor in motion, but when the watch is taken off this system is inert, which may affect the time-keeping accuracy of the watch. Using a quality watch winder will prevent your automatic watch from losing its accuracy.
