Convenience
The device relieves watch collectors of having to wind and reset the day/date of their self-winding automatic timepieces. Mechanical watches should be wound daily to remain in good working condition, according to Chronocentric.com.
The Machine
Watch winders feature a small motor powered by a battery or AC power outlet to rotate a pedestal that holds the watch.
Function
Watch winders function much the same way as the wrist by rotating the watch in various directions to keep it running.
Types
There are devices for a single watch or multiple watches depending on the size of a collector's inventory.
Features
Watch winders may feature a carousel or Ferris wheel configuration to move the watch in various directions.
