What is a watch winder?
Watch winder is a device with an electric motor and one or more rotating platforms, to automatically wind up your watch when you are not wearing it. A winder keeps an automatic watch running and ready to wear any times. It also serves to keep the lubricating oil inside the moving mechanism smoothly and evenly distributed, when you are not wearing your watch for a long period of time. A watch winder provides angular and/or circular motion that convert the motion's kinetic energy into stored micro electrical energy, so as to keep the watch movement running. Watch winders are only useful if your watch is an "automatic" or "self-winding" watch; watches like Rolex, Patek Philippe, Piaget, Tag Heuer, etc. A quartz watch does not need a watch winder.

Why use watch winder?

In short, a watch winder serves 3 functions :
1. Provide convenience and time savings to watch owners, and an ease of mind that your watch is ready to wear whenever you want, even if you do not wear the watch frequently;
2 Reduce an automatic watch's wear and tear, in particular to the crown winding mechanism;
3. Enhance the mechanical life of the watches.

An automatic watch usually has sufficient power reserve to run for only a couple to a few days, depends on the brands and the movement it uses. If you do not wear it for a few days, the watch will stop and you need to reset it and rewind it again.

For watches with complicate functions like moon phase or perpetual calendars, to reset and to rewind it could be quite a tedious task that most watch owners would like to avoid. If you have more than one watch, to wind up and to reset each will not only be time consuming and tedious, but frequently resetting and rewinding the watch could cause certain harm to the mechanism of the watches; and could also hamper the long term mechanical life and functionality of the watch.
