VENTURA V-TEC SIGMA MGS WATCH

The Ventura V-Tech Sigma MGS is "automatic" digital with all sorts of fancy, you have a scratch resistant case and crystal and then you have Venturas EasySkroll knob, which allows you to set the time, date, and other functions with one scroll wheel. You power the watch through the natural movement of your arm and there is a small rotor near the face which is connected to a micro-generator and battery.
