I do own a watch winder but I only use it on occasion as part of a process to test if a watch is keeping time.
Automatic watch winders can be had for as little as $50 but I read the other day about a watch winder for manual wind watches which I thought was unusual.
The Orbita Sempre is, according to the company that produces it, the only such winder on the market. It is intended to wind, without ever overwinding, virtually any manually wound mechanical watch. The Orbita watch winder accomplishes this feat with a system of precision collets (basically, mechanical fingers) that grasp the watch’s crown and replicate the action of finger winding.
As it does so, an ingenious microprocessor control senses the increasing resistance as the mainspring is being wound and automatically stops winding when the watch approaches the fully wound state. The Orbita Sempre comes in a single ($2,995) or double ($4,995) model, in either burl or black leather finish and you can read more about it at the companies website – www.orbita.com
