Pretty beat up automatic that still runs well, though a bit fast. The top right lug is bent a bit and a piece of the underside is missing. I'd imagine if someone were wearing it when it happened, they were hurt pretty bad. Having some trouble specifically identifying the model. "D" appears the closest as the other variants have different shaped lugs. (I think that is the right term.) Appears to be the original band.

Automatic is a movement with a swinging weight inside that winds a mainspring.
Hand wind is just that. A Duo-Wind is an early automatic that can also be wound by hand. Most all automatics (self winding) are Duo-wind.
Accutron, Accuquartz (an early quartz crystal /Accutron Hybrid) and quartz movements have their power supplied by a battery. The kinetic power to run the watch is from electrically stimulated vibration of a tuning fork (Accutron), quartz crystal or a combination (Accuquartz).
Subject watch is considered a self winding or automatic watch. Early automatics were referred to as Duo-wind, then self winding, and finally automatic.
Hand winding and automatics fall under the general category of "mechanical". All others are considered "electronic" for lack of a better word.
