A watch winder is a device that rotates an automatic watch to keep it wound and running when it is not being worn. This is important because automatic watches rely on the movement of the wearer’s arm to wind the mainspring, which provides the power to run the watch. If an automatic watch is not worn for an extended period of time, it will eventually stop running.
There are many different types of watch winders on the market, so it is important to choose one that is right for your needs. Factors to consider include the number of watches you need to wind, the size of your watches, and the type of watches you have.
