A watch winder is a tool to keep automatic watches powered so they don't stop and lose the current date and time. Most automatic watches have a power reserve of around 24-48 hours. Once you take the watch off your wrist the power reserve starts to run down and when the power is empty the watch will temporarily stop working and you will need to reset the time / date to wear it again. This is a common problem for people who don't wear their automatic watch for work or who have two plus watches and swap between them.
