Antique pocket watches generally have one of two ways to be wound: 1. A winding stem, similar to a windup wrist watch; 2. A winding key, like older wind up toys.
That's entirely dependent upon your definition of "antique." The Westclox Pocket Bens were made throughout the 1950s in LaSalle-Peru, IL. Perhaps these watches would be more correctly called "vintage."
The most popular way to sell pocket watches is through EBay. But to do that you need to have some idea of its value. This can vary greatly depending on the make of the watch, the type of movement, what it is made of and its overall condition. To get some idea of the value, you can google "Antique Pocket Watches" and visit the sites that sell pocket watches and see if one similar to yours is there.
