This is really nothing new—Seiko and Citizen have had versions of this movement for years. However, it's a very cool design. The Ventura V-Tech Sigma MGS is "automatic" digital with all sorts of fancy, Swiss tomfoolery in it. First, you have a scratch resistant case and crystal and then you have Ventura's 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. The resulting amalgam of fanciness and high-tech will cost you about $1,750 and should be available in the U.S. soon.
