Mimicking Human Motion
Automatic watches are regulated on the principal of winding themselves enabled by a weight which is not unmoving. The weight moves and keeps the automatic watch moving as well. During such times when the watches are not actually worn, the object which was moving inside the automatic watch can’t garner enough moving power and the watch runs down. The watch winder is the instrument which keeps such an issue from creeping up. It keeps the watch moving in a round pattern to simulate human movement and thus facilitates the self-winding movement of the watch to operate ceaselessly.
If you have a watch which you do not usually wear then perhaps you would not require a watch winder unless you need constant resetting of the complicated calendar feature, but in the event of wearing a watch frequently, though with small breaks, this is a device right up your necessity meter. This is because an automatic watch winder keeps such watches ready to be used at an immediate notice.
If you do not wear a part of your vintage collection, you can wind them manually and let them run down; the same option is not available for watches worn regularly.
